This video is an interview with Thomas Ericcson, Head of Production at Morakniv and a descendant of one of the founders. He has a wealth of practical experience. I was especially fascinated with his thoughts on "factory bevel angles".

One of my happy memories of visiting Tormek was meeting Sebastien. I was delighted to find him again on the Morakniv youtube channel. Tormek and Morakniv make a nice combination.

Much praise has been posted about the benefits of superabrasive wheels, both diamond and CBN. The diameters do not decrease with wear and they never need truing. While these are indeed formidable advantages, the praise chorus often overlooks a notable constraint. These marvelous wheels are single grit. Standard advice given to new users is often to purchase three diamond wheels or four or more CBN wheels. We are starting to see conflicting advice given to new users who want to purchase only one wheel due to budgetary constraints. Purchasing a set of superabrasive wheels can easily double the investment in a T8. What to do?

Our late very innovative member, Wootz (Vadim of Knife Grinders), did the preliminary work on a solution. Tragically, his death cut short the development of his ideas. One of his most promising ideas was the use of diamond plates for grading the SG and SB grinding wheels. While still not universally known or accepted, we now know that the concept of using the stone grader to change the grit from 220 to 1000 (only) was an oversimplification. For years, the concept of "600 grit" has been gradually entering the conversation. "600 grit" is a grit somewhere between 220 and 1000, a medium grit somewhere between 220 and 1000, as opposed to an exact number.

Wootz also introduced the idea that using a 1000 grit diamond plate to grade the SG could produce a grit similar to 1500 grit.  Wootz also introduced using the 80 grit diamond plate to set the SB wheel to coarse without having some grains standing proud. Wootz left us some interesting ares to further develop.

I do not mean to minimize the importance of the stone grader. For the many years when the SG was the only available grinding wheel, the stone grader provided a way for the Super Grind (SG wheel) to also grind like the finer (smoother finish) discontinued natural sandstone grinding wheel.

My question for my fellow forum members is have we explored the limits of the grading potential of the SG and SB wheels? If, as Wootz said, a 1000 grit diamond plate will produce 1500 grit with the SG, will a 2000 grit plate produce an even finer grit? Or, is a 1000 grit the maximum for making the SG finer? What about varying grits with the SB or intermediate grits with either the SG or SB?

I recently ordered half a dozen diamond plates in various grits from 80 to 2000 from Amazon. At around $10 US each, they were not expensive. Three or four would provide the average Tormek home user with plenty of versatility at a fraction of the cost of a set of superabrasive wheels.

I welcome your thoughts.

I received this PM from Daniel Kraichuk, Vadim's son, this morning. Several people have inquired about purchasing KG products. Of the remaining two products, I purchased one of the 400 grit round corner CBN wheels from KG several years ago. I don't normally like to recommend third party products, however, Wootz (Vadim) was a friend and longtime faithful member who contributed much to this forum and to knife sharpening, so I will make an exception.

I purchased my 400 grit wheel as a versatile grit size for knife sharpening and for the radius corners to facilitate sharpening inside corners. The quality is impressive, which I expected from Wootz.

Anyone wishing to purchase either of these items should follow Daniel's requested order method.

Daniel is a fine, responsible young man. We wish him the very best in preparing for his engineering career. Wootz left him a fine life example to follow.

Ken

Good Afternoon Ken,
This is Daniel Kraichuk, Vadim's son from KnifeGrinders.

First of all, I highly thank you for your persistent gratitude towards my father's work on this Tormek forum as well as the condolences shared by you and other people from this community.

I am sending you a PM to hopefully have you share information to those interested in what we have left in our stock that I would like to sell the rest of quickly. This is because I am finishing high school in a couple weeks and am planning to pursue an engineering and/or product design course at university, maybe someday to continue my dad's legacy in the engineering field.

Regarding the items, all that we have left to sell are:
- #160 Dual-Fit CBN Wheels
- and a few #400 Round-Edge CBN Wheels
If needed, better to e-mail me as for many they can't be purchased through our website anymore (excluding eBooks and Softwares).

The reason that it is you particularly that I'm texting is because of your many contributions in helping people with our products and recognising Vadim's work; Also, because I am unsure of where, or to who I should share this information to.

It'd be great if you would be able to help us out on this matter, but if not, that is completely ok as we are in no serious rush.

Once again, thank you for your contributions.

If you are going to reply/respond to this PM, please do so through e-mail at daniel.kraichuk@gmail.com as it is easier for me to use.

Kindest Regards,
Daniel Vadimovich Kraichuk

I remember recently watching a video where the presenter used the lid of an EM-15 edge marker instead of his thumb nail. I tried this, and it seemed to work well. My knife slid along smoothly until it hit a rough patch. I have never been comfortable using my thumb nail.

I held off posting this because I have not been able to find the source and post a link. I would be most appreciative if anyone remembered the source and would post a link. For that matter, I would welcome good information either supporting or disproving the marker top idea.

Thanks in advance.

I do not pretend that Tormek is infallible of the only source of good information.
I do believe that the Tormek technique and ideas are solid and based on fifty years experience. With that in mind, I will suggest that new users confine their studies to the handbook and the Tormek online classes. Also, I suggest foregoing purchases from third party vendors initially.

I can foresee some resistance to this idea, and extra explanation is needed. Probably the most prevalent other source of information isthe book and videos by our friend and member the late Vadim Kriachuk of Knife Grinders Australia, known to us by his forum name of Wootz. I hold Wootz in the highest fond regards and do not disagree with his methods. However, I believe his ideas are more appropriate for more advanced users.

Nor do I have any complaints with the present third party vendors of Tormek related products. Over the years, I have purchased products from most of them and have always found the service and products satisfactory. I include CBN wheels in this comment.

For new users, I recommend only the SG grinding wheel. I am not alone in this. This is the preferred grinding wheel of the Tormek instructors on the online classes, who have ready access to any of the Tormek wheels if they desire. The SG wheel is also recommended by several experienced forum members. No diamond or CBN wheels. No SJ or SB wheels or off brand wheels. The SG is rugged and can be graded to different grits.

Stick with the Tormek leather honing wheel and PA-70 honing compound. No third party felt or MDF wheels or other honing compounds, including diamond compounds.

I do not mean this to sound narrow minded. My point is to really master the basic traditional Tormek technique. Once you have this solid foundation, you can intelligently explore other options. If you start with CBN, diamond, or the SJ wheel prematurely, you will not master the basic technique. (Sharpening three knives does not qualify as a suitable apprenticeship period.)

The handbook and online classes are valuable learning references. I have read through the handbook several times over the years and am rewatching the online  the online classes regularly. I continue learning from them.

i like the videos by isharpen. This video, about truing his SG-250, seems very well done and thorough. Here is a link:

This video is about a knife sharpening master class using a Tormek with two Morakniv experts. It is definitely must see. If you prefer, itis also available in three shorter videos on the same channel.

I have heard the KJ-45 criticized because, unlike the earlier SVM-45, the end stop is not adjustable. While this is true, it is possible to minimize this. I have also heard that there may be too much play in the support bar. My suggestion may also minimize this, also.

In one of the online classes, Wolfgang states his preference for using the microadjust to raise the support bar instead of lowering it. Raising the support bar keeps the microadjust under constant, consistent tension. This is more controllable than having to tap the support bar when lowering the support bar.

My plan is to only adjust the height of the support bar in one direction, raising it with constant tension.

Let us take the hypothetical of half a dozen to a dozen knives of different widths to be sharpened. These knives are of various sizes, the key variable being the width of the knives. Lay out the knives from the narrowest width to the widest.


Place the narrowest knife in the KJ-45 and set it up with the KS-123. Sharpen the knife. Then set up to hone, either freehand or with a separate support bar and a FVB. Hone the knife before removing it from the jig.


Place the next widest knife in the jig. raise the support bar carefully until this knife is properly set, using one directional raising only. This procedure will insure minimum setting movement and maximum accuracy. Set up the honing support bar the same way.

Some thoughts:
This method works most efficiently if all the knives are ground to the same bevel angle. However, changing the bevel angles is certainly possible, with only a bit more work.

This procedure is based upon several ideas from both forum members and Tormek staff. I make no claim on originality. I also do not consider it a completed procedure. I welcome comments and suggestions. I realize that with the variety in knives that an ideal technique may vary for different kinds and sizes of knives. Included techniques may probably include different knife jigs and calculators. The volume of sharpening will also effect the choice of techniques.

We often see ACC (Tormek Anti Corrosion Concentrate) described as "expensive". Sometimes this is even listed as a con in pro and con descriptions of diamond wheels.ñ What I have not seen is "expensive" explained in actual usage costs. Nor have I seen the full benefits of ACC included in these criticisms.

Here are my questions for those of you using diamond wheels and ACC:

Every new diamond wheel includes one 150ml bottle of ACC. At the recommended dilution of 1:25, and the T8 water trough holding 125ml of water and 5ml of ACC, this included bottle should ideally provide thirty fresh sharpening sessions. This number will be influenced both by any spillage and how often the diluted solution is reused. The question is, have you used the ACC enough to require purchasing more?

Approximately how many knives or tools will one bottle of ACC last the way you sharpen? Related to this, for those who sharpen professionally, how much revenue will this number of knives or tools produce?

I hope this topic will provide a better definition of what "expensive" is.

Ken

I found this video interesting. Although the presenter uses two high speed dry grinders and both CBN and conventional grinding wheels, his thoughts could be applied to a Tormek and diamond and/or conventional grinding wheels.

He describes himself as an active hobbiest woodturner who does sell some bowls. For several years, he used his $120 eight inch dry grinder with the 80 and 120 grit supplied grinding wheels. He found this combination satisfactory for his needs. Then he upgraded to a one horsepower grinder with 80 and 600 grit CBN wheels. He basically had no complaints with the sharpening quality of his new thiusand dollar rig. It works as wel as his old one hundred twenty dollar rig. He did note that the old rig required a fifteen dollar diamond T truing and dressing tool.

His criticism of the new rig was that, for his essentially hobbiest use, he felt the much larger cost was overkill. In fairness, I must also state, that a set up with a couple diamond wheels could also be considered overkill for him.

There is nothing wrong with a fancy CBN or diamond rig, although for many years we made do with an SG-250 at most more modest cost. Since almost sharpening is restoring the existing bevel, the old combination still works for thrifty sharpeners. Here is a link:

EDIT: When I first posted this topic, I inadvertently typed "KS-123" instead of ?"KJ-45".

Now that we have had the chance to use the KJ-45 knife setting jig, I am curious to know your experiences with using it for convexing edges.

Have you used it to convex edges?

If so, did you use it once out of curiosity or has convexing become part of your regular sharpening program?

If convexing is now part of your regular sharpening program, which knives do you convex? (function and thickness)

For those of you who sharpen professionally, do your customers request convexing, and do you add a surcharge for it?

I have no hidden agenda pro or con, just curiosity to learn the wisdom and experience of the forum.

This intimate look at Swiss Army Knives reminded me very much of the warm feelings of my visit last summer to Tormek.
Enjoy, Ken

This came in from a new member and somehow,the message got confused in the pixels.
Advice from you turners wouls be appreciated.
Thanks, Ken

Sorry if this has been asked, many times, before! I have a bowl gouge with a 30 degree bevel (it's def a BG!) I will re-grind most probably very soon but for now, how do I set the jig on my T8 to sharpen this, please? Does not appear to be a setting for this. I presume I cannot treat it as a spindle gouge?

 There is an English language expression, "sea change", meaning "a profound or notable transformation" (source: Oxford Dictionary).

One comment during the online class 24 about the KS-123 was that the more jigs which were added, the slower Tormek sharpening became. While there is an element of truth in this, the complete picture is that these more advanced jigs also make the sharpening more accurate. Not many Tormek sharpeners want to refurn to just freehand sharpening and honing.
Of the present ongoing sea changes, the first seems to be the US-430, an evolution of the out of production US-400 support bar. At the request of a group of Tormek owners lead by Tormek dealer, Steve Bottorff, Tormek agreed to making a limited run of the US-400. I was proud to have been a part of that group. This limited run sold out quickly. I was also at least one of those who suggested that Tormek extend the two side legs, which created the present US-430. A useful tool was added to the Tormek system. (It should be noted that the US-430 is really for long knives only.)

For years, we grumbled about the SVM jigs not being automatically self centering. Tormek corrected this with the introduction of the KJ knife jigs. This seems an ongoing change, as a number of us are still not content with the reduced adjustability of the KJ. However, the KJ jigs do provide self centering at very reasonable cost.

The new KS-123 is a major step forward. In my opinion, the Tormek Design Committee really nailed the issue of using the Amglemaster with knives. We can now reserve the Anglemaster, a fine tool, for its intended purpose, flat chisels and plane irons.

Related to the KS-123 change is an even bigger sea change. Tormek has tradionally recommended freehand honing. Withlonger knives, jig honing did not work because of clearance problems with the jig and the plastic locking knobs. Pioneered by late forum member, Wootz, of Knife Grinders, many of us purchased third party Frontal Vertical Bases, which solved the clearance problem. This clever solution, just adding two holes to the MB-100, offered two functions for about the same cost as either of the two jigs. I do not believe Tormek has or will completely abandon freehand honing, although their recent comments seem to have warmed considerably to it.
When I first started using my T7 in 2009, I felt that certain areas of sharpening had advanced more with Tormek. I felt that knife sharpening was not the most area. With recent changes, I no longer feel that way. "Sharpening Innovations" is a good description of Tormek.

One of my very few disagreements with the online classes is about replacement "transport spacers" This little spacer keeps the shaft aligned when the grinding wheel is removed. Unfortunately, it is frequently lost or discarded. When viewers question how to get a replacement, they are told to make one out of wood or similar materials. I think this is poor advice. Yes, I have made several out of plastic water pipe; however, I have a drill press. Complaints to Tormek and a prominent parts dealer went nowhere.

Last August, during my visit to Tormek, I had the good fortune to meet John and Darren Of Sharpening Supplies. I shared my complaint with them. They told me they would look into it. To my surprise, the spacer was listed on their website, along with several other hard to find parts. I immediately ordered one. Darren emailed me to let me know that my order would be complimentary, a nice touch.

Two bits of advice:

First, for those who still have their spacer, mark it "SAVE" with a Sharpie.

Second, make a note to include a couple with your next Sharpening Supplies order.

The spacers themselves are very inexpensive; it's shipping which drives up the cost. Combining them with other products softens the shipping cost.

I have been working with Dutchman's Grinding Angle tables for more than ten years. Even without an extensive math background, "Projection", Distance", "Bevel Angle", and "Changes in wheel diameter" have become comfortable old friends. I have Dutchman's tables downloaded on my ipad and printed copies scattered throughout my house.

I will readily admit that my kenjig has been completely outgunned by the KS-123 and that it will soon become mostly a relic. Both operate on the same theory; however, the KS-123 is far more sophisticated.

I had the rare opportunity of being in a discussion group with both Per and Håkan, independent designers of very similar jigs. Håkan kindly presented with a prototype jig.

Without the benefit of instructions or an online class, I had some initial difficulties understanding the KS-123; however these were soon surpassed. The online class greatly shortens the learning curve.

One concept which has been mentioned in several classes, but never fully explained is the concept of loading. Woodworkers encounter this all the time with hand plane depth adjustment screws. The same is true with adjusting wheels in machine shops. For precise adjustment, one should always  try to move the screw  ( with the Tormek that means moving the microadjust upward. This eliminates the "slop" . Either direction will get the job done; eliminating the slop just is a little better.

I will not be discarding my Anglemaster. I will move it from my knife jig to my square edge tools, where it was originally designed to be used. It functions very well with chisels and plane blades, especially with good light.

Ken

PS The most pleasant surprise with the KS-123 was the price. Having worked with a prototype, I honestly expected the price to be double the $50 US. And, instead of my present nine knife jigs, I could do the job with only one KJ-45 (possibly adding a KJ-140 if I ever purchase a long , thin filleting knife, which is doubtful).

An interesting way of precisely sharpening spokeshave blades:
