All joking aside, I can’t wait to finish the designs and get all these things into production. It always takes so much longer than I want.
The problem has always been there is no constant radius for serrations you find. Even within a manufacturer’s line, you’ll find a variety of radii used. The “best” solution I’ve found is either a tapered rod, like DMT uses (you will find the radius you need but they will “wallow it out a bit as you go along) or a single point of contact (like the triangle edge of a Sharpmaker) where it’s easy to wear the tips.
The only “real” solution is to have a variety of different sized rods and fit them to the serrations you have (or redo all the serrations to fit the rod you have, which changes the knive’s design.)
Like many, I tend to avoid serrations, but I have a few (under a dozen 😉 )
