Like some I have limited experience with Ti knives.

I do know that they were used by my previous company Wedgwood for cutting wet clay as part of the production process*. These particular knives similar to scalpels were sharpened regularly, but less frequently than steel. They did however have to be sharpened on dedicated grinding wheels, possibly due to there hardness.

(*Typical application trimming the edge of an 12 inch dinner plate. Each knife would trim 300 plates a hour. Production running continously, 24/7, automated system. Average resharpening period once every 2 months. So for those who love the maths, how many miles of clay are cut between resharpenings?) <img src="/images/graemlins/grin.gif" alt="" />
