"There is some difference in more full blade thickness of the Yard Guard, but most of the difference is probably the thickness of the blades."

No argument here.

The only $.02 i can add is that i love the shape of the Chopweiler handle, with its formidable palm-swell. It's well... Swell. - i can let my grip hang waaay back for really hard swings, and find it almost impossible to drop, or choke up and i seem to be able to hold it with a looser grip, and experience less fatigue than just about any full-tang-with-scales handle i've tried. Awesome ergodynamics (at least for me).
But -- it sure is hard to beat the comfort of that Res-c. I spoze a Res-c handle shaped like the Chopweiler handle would be ideal for me, though that's hardly worth mentioning... <img src="/ubbthreads/images/graemlins/blush.gif" alt="" /> Oh - almost forgot -- the recurve and thickness of the blade is what makes me turn to my YardHook for chopping tasks over just about any knife in its size-range -- wow what a chopper! The Chopwieler almost brings me over the line between compromising the diversity of a straight edge or one with a slight belly. It's hard to slice potatoes with the YardHook, for instance... Great thread and interesting comparison!!!!
