Hello
Just a follow up on tip sharpening. I am a little confused when it comes to the correct correct technique for sharpen a curved tip. According to the videos I should pick up the knife when I approach the curved tip. But in which direction. Should it be parallell to the stone radius?
Found this video on Youtube which gives the correct solution, but I have a litte trouble with transfering this technique to the round tormek stone:
The short answer... if there isn't a lot of curve in the belly/tip area, you can just lift the handle as you approach the tip. If there is a lot of curve, then rotation is the better method. In some cases, you have to do a bit of both. There is a thread that talks about this in length... To Pivot or Not to Pivot.
The other issue though, is setting the knife in the clamp so that, when you rotate the knife, the contact area on the stone doesn't move, because (as you already figured out) that will change the angle. That is shown in this thread... The One Change You Should Make to the Tormek.
Jan has created a template for setting the knife in the (unmodified) jig that will help keep it in the correct location... Knife Point Setting Template.
So to summarizethere is no real "right" method. The easiest way is to get a few practice knives, mark the bevel with a Sharpie marker, and practice both methods (lifting and/or pivoting), to see what works best for you. One main point to remember... where you place the belly/tip area in relation to the clamp, will determine the angle that it is sharpened at. (This is what Jan's template helps with).
Thank you very much for a very good answer. I see that I have a lot to read before I really masters the Tormek. Comming from 5 years with free hand sharpening on japanese water stone I thought that Tormek should be easy to use:)
