I see some makers do this regularly and also round the choil area while others such as myself not so much. I've made one blade with a rounded spine and have owned another from a different maker. Aside from being an extra step in the process I didn't feel that the comfort level was far superior to just knocking of the edges of the spine and choil area, which I do regularly. My wife says it's because over the years with knife making my hands are now at 80 grit. Am I missing something? Does this feature make a knife more marketable/desirable? I would not mind doing this in the future if it makes my work more marketable. I'm interested to hear any experiences from makers and non makers.
