Regular titanium is softer than hardened steel, so it doesn't hold an edge very well. There's something called titanium carbide which is harder, but I'm not sure what its other properties are -- wikipedia calls it a ceramic so I'm not sure if that'd be strong enough to use as an edge.

I looked up Batalean's marketing blurb and they claim the edges are made of "Titanal", which is a rather funny word. Presumably they've added something to the titanium in order to trade tensile strength for hardness. I couldn't find any info on Burton's site about their edges.

I guess I've been turning into a materials dork recently..

edit: beat'd by grizz. only one point of disagreement: if I have it right, titanium isn't brittle, it's just soft compared to hardened steels

edit 2: There are some pros for titanium as an edge material though: It won't rust and it's light.
