I have found the William Henry series to be excellent in every aspect. As stated before, they are somewhat light duty, but I bet their overall strength would supprise most people. They are put together very well, and QC is outstanding.
I have a Cocobolo, spearpoint Evolution that I carried to work everyday. It is very nice, especially for the price tag. I also have a carbon fiber Lancet model. This one is a lot more costly, but it is top notch. The Evolution series are nice, and the price does reflect that, but, if you want an outstanding William Henry, go with the American made models.
