Hello. I am trying to sharpen a knife for a buddy and the blade has a diamond cross section.. I have tried to use the KJ-45 but I am having trouble securing the blade in the jig. The blade wobbles along the long axis and screws up my angle. Any suggestions on sharpening diamond shaped blades? Thanks.
What I've been doing with odd shaped blades, is to add equal layers of adhesive tape on both sides to increase thickness/adjust its shape.(I typically increase the thickness for extremely thin blades to raise my jig away from the grindstone)
It really doesn't matter to me if the KJ-45 is not closely clamped to the blade. As long as the blade doesn't wobble during sharpening, I was never affected by a wide clamp holding a thin/odd shaped blade.
