Grade of Titanium on the Albatros?

[gytheran]

I just picked up a couple of the Albatros knives that were on woot today and was wondering what grade of titanium is used for the handle?

Thanks

The ti seemed decent, but those bad boys are lock rock kings. I have tried several, older and newer. All solid when new but with LIGHT use developed horrible lock rock. But what you paid for them, they would make cool christmas gifts.
