Quote from: skärparn on September 15, 2024, 07:41:39 PMHi! Been using T8 about 6 months. Often pleased with the results but I have one big problem. Some knifes, havent yet seen the exact pattern, gets a wierd shape of the blade after sharpening. Same problem both with KJ-140 and 45. Please see attached images. Can someone point out what Im doing wrong?I think it is quite common for many kitchen knives to have this shape already. Probably due to sharpening on a honing steel (or sharpening steel) like these

Unfortunately, a lot of users use these mostly in the middle and the tip of the knife and very rarely right at the heel. Over time the knives end up like the ones in your photo.
Did you notice or check that the knives with this problem were like this before you try to sharpen them on the Tormek? You can use a straight edge or just look down carefully into the light to check.
The Tormek will not get rid of this with normal style of sharpening. You either need to spend more time on the heel as others have said and/or grind the heel part down on a grinder with coarser grit first. If you do this, be careful not to let the blade get hot.
