Question: can the back edge of the heel section be slightly chamfered? would this help finger fatigue for people who rest their middle finger against this edge for a long time. I saw this little feature on a Kitaeji knife from Shigefusa, thought it was a good idea
I normally round the back edges but only slightly and have been thinking (at Daniel EE's advice) that I need to completely round this area for just the reason you are saying. I'll have to give it a try.
