I think titanium only get to about 44-46 on the Rockwell C scale. Not to good for knives. However George Lambert of Titan Knife Technologies makes some titanium fillet knives with the edge treated with the Rocklin Roclizer that perform out of this world. It impregnates tungsten carbide into the titanium on one side of the edge.
I had him treat a $4 dollar cheap knife and a cheap Gerber knife for me. The $4 knife with about 3 1/2" blade got 200 cuts on 3/4 hemp rope. This is a different type edge than most folks are used to. It will not shave arm hair, but will cut anything very well that you would expect a pocketknife to cut. I do not know how many cuts the Gerber will get because it is a paraframe handle and my hand started hurting before it went dull. Resharpening is also very easy. You only sharpen the untreated side, and you are back in business.
