I own some of the best knives available since the 1970's. I have the Randal's, Microtech Autos, Chris Reeves (just about all their fixed and folders), Benchmade, High-end Spyderco's by the dozen. I have just about everything one could imagine and love them very much. But, there is nothing that has ever come close to the Rockstead Shu folding pocket knife, in ZDP-189. This is simply the grail folder. I'm not going to spend a whole bunch of time trying to explain it because it has to be experienced. The photos are terrific and inspiring, but the actual tool in hand it the clincher. If you are a Pocket knife and blade enthusiast, take out a loan, charge it on your credit card, but hopefully pay cash for a Rockstead. I have the Shu Model, and this is the top of the line--bar none.
