I just bought a William Henry 'Quest' with 3.25" zdp/'wave' damascus blade. I bought it for carry while running. I had an old WH ti-carbon with 154-CM blade and had thought about the 'Quest' for a while, and finally got tired of waiting for something better to come along.
Like any WH, the 'Quest' is incredible, but it weighs 2.1 oz (contrary to the web site's spec of 1.6 oz). Damn, it's big for a WH, but I kind of like that. I also like the tip-up pocket clip.
It bounces around much more than the old knife, which weighed only 1.45 oz. It is not very smooth opening, negating the advantage of tip-up carry. Maybe I will get better with it with practice. I have never been sold on the button lock. All in all I like it and am keeping it, but it seems like 2 steps forward and one backward.
