Sandblast, Ti, and sharpeners

[Shorttime]

I've been thinking about beads, lanyards, and other gear accessories lately. I'm not really into this stuff, but a post in another thread got me thinking about ways that accessories could be made to serve other purposes.

I've seen sandblasted titanium rings, and the finish looks rough enough to serve as a sharpener. I guess the question is whether or not Ti is hard enough to actually abrade steel.

Would a sandblasted titanium ring work as a sharpener? What do you guys think?
