I have a few folder designs that I will be prototyping soon. The liner lock will be titanium and so I experimented anodizing with a couple of spoons. I recently picked up an aluminum pen from Kara's Kustoms. I R & R'ed the stock clip with a titanium clip I made and anodized. I'm pleased with the results and it's always fun to try something new.
The other nice thing about anodizing is that parts will be easy to make with our laser. This should work nicely with a titanium key chain bottle opener that I designed. The opener will be titanium with an exotic hardwood attached.
