THere's only so many ways to make a knife. We've been doing it for 1,000's of years. Look around enough and you'll find someone before you made what you're making. Only thing that changes is materials.
I've made some through trial and error in total isolation that fit and felt and worked great. Then after the fact saw very similar that were out there already.
Different alloys allow thinner blades or different grinds, but ultimately the interface with the user is unchanged.
