Wow great responses in this thread so far! I can't believe somebody would stand on their Benchmade in between two bricks...I mean sure it's a great testament to the strength of the Grip but I would never be inclined to do that. So the BM is lighter, seemingly just as sturdy, and also a little easier to operate, but the Manix is quite a bit heavier in the pocket, but more robust and possibly sturdier overall, and also has the G10 handle with better jimping than the BM. Have any of you noticed spring failure in either of these models requiring replacement? Tough choices...
