I had been doing some wood carving with a Leatherman Crater and quickly discovered everything a carving knife should NOT be.
So I made a handle from meranti dowel and shaped it to be comfortable for both push and pull cuts. I took a piece of bimetal blade and ground down the teeth with a small angle grinder.
There was still some of that waviness on the edge which I tried to straighten out with a hammer and steel chisel.
I then ground a cutting edge, trying to not push the very edge back from where the tooth gullet had been. The idea was to end up with a high speed steel edge that would not require frequent sharpening.
I was unable to completely iron out all the waves which resulted in an edge bevel of varying width. It might also have resulted in areas not quite as sharp as the rest. It sharpened up to at least on par with the Crater though and retained its "carvability" for much longer. That might just be because of how thin it is rather than actual edge retention.
The blade is obviously quite flexible which has its uses for carving but it makes it tricky to keep an even pressure along the length for sharpening.
Is there any merit in my reasoning behind a durable HSS edge? Does the HSS even extend back past the tooth gullet?
If so, can anyone tell me how wide the actual piece of HSS is? If there is enough HSS meat left I can grind the edge a little further back and out of the wavy area.
It was so quick and easy I am considering doing the same with a sabre saw blade.
