Tormek T-1 and T-2 / Re: Starting Knife Sharpening ...
Last post by John Hancock Sr - October 12, 2024, 06:47:41 AMThe T1 is an excellent choice for sharpening your standard kitchen knife. The diamond wheel and composite hone will give you more than satisfactory knives of any hardness.
On the down side it will not handle specialty knives. You are pretty much limited to standard shape knives. You may find you loose custom to sharpeners who offer a wider range of services. You will also not be able to repair chips or breaks. These take additional equipment.
If simply sharpening your standard kitchen knife is what you are after then the T1 is ideal.
As for price google knife sharpeners in your area and see what the going rate is.

Tormek T-1 and T-2 / Starting Knife Sharpening Busi...
Last post by keo - October 12, 2024, 03:15:17 AMHello. Looking to the community for thoughts and comments on using my T1 to start a small knife sharpening table at a local farmer's market. What would you charge per knife? Do you think it worth it. Goal is to keep it small. No interest in growing big. Thank you.

General Tormek Questions / Re: KS-123 For Chisels

Even then it would not be accurate since the jig is specifically designed to use with the knife jigs which center lines are sitting a specific distance above the bar. I have not checked but if the Square Edge jig is a different distance above the bar then the geometry will be out.
Correct ! My bad.

General Tormek Questions / Re: KS-123 For Chisels
Last post by Ken S - October 10, 2024, 05:32:42 PMI believe the FVB (frontal vertical base invented by our late member Wootz) has been and will continue to be a game changer. My first experience with grinding away or into was with Steve Bottorff. Steve grinds almost all of the knives he sharpens away. The all to often overlooked factor in this is that from long experience and the time pressures of a busy farmers market schedule, Steve became very proficient in freehand sharpening. Freehand sharpening is much safer grinding away.
The FVB opens up new options by allowing vertical positioning in grinding away. I have long recommended having at least a couple 3/4" bench chisels (I recommend Irwin Blue Chip chisels. They are reasonably priced and reasonable quality.) Use them as learning/practice tools. I recommend having at least two in the same width. I actually have around a dozen, all 3/4" width.
Wootz (Vadim of Knife Grinders) was a real sharpening pioneer. He did much to advance sharpening. However, he was not the only pioneer and sharpening continues to evolve. Reasonably priced, reasonable quality learning/practice tools are essential parts of our learning kits.
Catches can be reduced by slightly rounding the two corners of the grinding wheels. ((Do not do this with diamond or CBN wheels or you will ruin them.)

Last post by tgbto - October 10, 2024, 08:14:05 AMIn addition, as a general rule, edge leading tends to avoid creating a thin, fragile burr that can get torn off when honing, messing up the apex.
The only downsides to edge leading that I can think of are :
- more aggressive at the APEX, but then also more efficient
- higher risk of "catching", but that won't happen with jigs that are fixed wrt the support bar.

General Tormek Questions / Re: KS-123 For Chisels
Last post by Ken S - October 10, 2024, 04:13:00 AMGood question. Chisels are normally sharpened edge leading. This allows greater control by observing the water flow over the blade. If you have not watched the online class on chisels and plane blades, I highly recommend it. It is available in Swedish, English, French, and German. Here is a link:

Knife Sharpening / Re: Titanium Cutting Boards
Last post by Royale - October 09, 2024, 09:23:52 AMI have a strong hunch that these "titanium cutting boards" are actually titanium nitride coated boards.
Nothing beyond hyperbole and a very stretched reality.

General Tormek Questions / Re: KS-123 For Chisels
Last post by Ken S - October 09, 2024, 07:30:26 AMA tool for setting grinding angles ideally should excel in three functions:
1) setting the Distance between the support and the grinding wheel
2) automatically compensating for different wheel diameters, especially for wheel
wear
3) setting the Projection
The TTS-100 excels in all three of these functions with woodturning tools, for which it was designed.
Used for chisels and plane irons, it excels in the first two functions and can be adapted to be quite adequate for the third function. In my opinion, it can give superior accuracy than any programs which rely on measuring with digital calipers. This is a statement which requires supporting evidence.
In the precision machine shop environment, measuring tools are chosen for their inherent accuracy. The top of the totem pole are precision gage blocks. Gage blocks are precision ground from carbide or hardened tool steel. They are made in three grades, shop floor, inspection and laboratory. Laboratory grade blocks have tolerances within millionths of an inch and are returned in regularintervals to the National Bureau of Standards for recalibration. They are kept in climate controlled rooms and reserved for the most demanding work.
Our work setting angles with the Tormek is far less demanding. In fact, even digital calipers are far more accurate than is required. The weakest link is any system which requires constant measuring. The benefit of a tool like the TTS-100 is repeatability. Whether the actual angle is plus or minus half a degree off of 25°, or whatever angle is chosen really does not matter. Even though the TTS-100 is plastic, the settings for all the chisels will be consistent, as no individual measurement is required.
The setting apps are useful tools. I just don't think they are needed for everyday chisel sharpening.
