Here is one of the new 5.11 Tactical knives I have been carrying.
The "First Responder" spearpoint model.
BLADE: 3 7/16th inches long s30v stainless and G-10 scales over full steel liners that are just under 1/8th inch thick.
(shaves hair even in the serrated part)

The blade is just under 3/16th inches THICK!

5.11 Tactical refers to it as a framelock, but some quibble with that since the lock is under the scale, but with a liner lock that thick, it comes close!

The lock is dead solid, with no trace of play and hasn't budged under testing.
On the end is a "striker plate", that I guess could be used for blunt non-lethal impact, or as a glass breaker.

This is one heavy duty folder!
