The biggest place I look for on the 'liner' vs frame lock on the JYD II and the Tyrade is the cutout on the frame lock where the metal bends into the blade channel. It seems there is more metal on these two, backed up by strong G10, then I have seen on many or even most frame locks. Looking at my two JYD IIs it does seem the titanium in the cutout is thicker though. I do wonder which would ultimately be stronger.

Is that the full sized skirmish or the mini?
