I just received a Large Chinese Folder made by Bob. The blade is 440V and it has polished carbon fiber scales. What I've notived about Bob's knives is that the lock up on the liner lock is as perfectly solid as it is going to get. There is no play at all in the blade. I think it was mentioned before, but about the only thing that there is to complain about is that the pocket clip, which is also handmade, shows tool work from bending of the Ti. I am growing very fond of the wide leaf-shaped blade. I think Bob has developed a style all his own when it comes to the Chinese Folder.
