I may have missed this, but has anyone experience with sharpening an edge of a titanium spork for use as a knife? I'd think given it is titanium, one would need to start with an angle or wheel grinder and then a file to get an edge on it. And I don;t know if a file would work on titanium. Maybe a stone instead. I like my wpork, and continue to use it in spite of having a plastic double ended spoon fork thing that likely weighs less.

If I recall correctly titanium work hardens which is why it is so difficult to machine. Grinding it should work, but I also have heard that titanium is pyrophoric so it might give off a nice shower of bright sparks that burn in the air, not the usual red specks that grinding steel gives.

I think it's worth a try; I had the thought myself but just haven't gotten around to it.

I tried sharpening a titanium knife from a GSI cutlery set once. The result, *for the alloy they had used*, was pathetic. It was a bit like sharpening soft aluminium or soft stainless steel. I can only conclude it was a soft alloy or pure titanium.

I have also tried grinding a hard 6Al-4V titanium alloy. This stuff does grind, but you need to be a little careful as it does not behave like steel. Actually, it is as tough and hard as ...

The sparks are not much of a problem in my experience.

Not as far as I know - which may be limited.
The good 6Al-4V alloy does not *need* to work harden ... but it WILL crack if you try bending it cold.

Don't you run the risk of cutting your lip if you make an effective knife edge on your spork?

I was just thinking the same thing. That would be a little too dangerous for me. Personally, I rather carry a Ti knife than run the risk of slicing my lips wide open on a trail.
