OK. I solved the mystery as to why I thought the M6 blade was thicker than .25". I stored the M6 by my SR Mini Mojo. The Mini Mojo has a .25" blade thickness too. The M6 felt much more substantial in my hand. So I measured the M6 this morning and they're both the same blade thickness. Hmmmm. I put the handles of both knives side-by-side, flip them vertical, and lo and behold the Gray M6 seems to have magnum thickness handle slabs!! The slabs are definitely thicker than those on the SR Mini Mojo, which seems to have BATAC thickness handle slabs.
So there you have it. I wasn't losing my mind....well not completely anyway <img src="/ubbthreads/images/graemlins/wink.gif" alt="" /> <img src="/ubbthreads/images/graemlins/grin.gif" alt="" />
