Ti-6-4 can be used ok for a cutting edge if you lay down some carbide on one side, and do a chisel grind. It ends up being like a beaver tooth and self sharpens. It never is as sharp as a steel edge, but perpetually maintains a good enough edge and it good for things like a utility knife, for box breakdown etc.

To DIY carbidize you need a dremel engraver or similar, a carbide mill bit (broken ones work great) and a power source that can do around 50v up to 2 amps.
This seems like a very handy little tool, and a lot more functional/better designed than a lot of One Piece Tools out there.If they ever hit production, let me know- I'd be down for one for sure.Def
Six months later: first time I use the cap lifter IRL: It works, But could have been better if I did keep the lifting part squared and "sharp angled" instead of sanding it round ....
Thanks guys (Image removed from quote.)
Pretty cool idea and execution.
Those inserts on the Sentinel are original or made by you? What is the other SAK?

"inserts" == "pinned brass rods" ? if so, then yes, it is homemade The other one is a ClassicSD, i'm on a Ti Rambler project now ...Here is the Sentry WIP (and the scalese for the next Ti Rambler were done that day) http://forum.multitool.org/index.php/topic,64155.msg1213719.html#msg1213719
Thanks! I meant the three holes. Seemed like something inserted in the scale, not drilled. I discovered the thread with all the info on the knife today...
