Checking the hardness factor of the Titanium diboride it is as abrasion resistant as titanium carbide and more than 3x harder than hardenable structural steels, I would guess it may need silicone carbide or diamond to grind. Make a stub tang small knife is all I can say unless you know someone who can weld a titanium tang onto it. We had this stuff in our shop once, the machinists cussed it and hated it, ended up in the grind shop for machining. It is weldable, but only by an experienced TIG welder. Making a folder is not for a beginner. Do not let a welder with no experience with titanium touch it or most machinists. Very uncommon material. Invest in some good diamond files if you want to make a folder and carbide drill bits. As for edge retention I will say this about titanium alloys I have run across, they don't make good cutting knives, but this stuff I do not know.
