Okay, after bitching in this very thread about Emerson quality I decided to put my money where my mouth is, I dusted of my 2000 CQC7 (I haven't carried it in at least 3 years) and touched up the edge and took it apart. I made a slight adjustment to the liner lock to make the lockup more secure, firmed up the detent and took it outside.
I made 35 hard cuts to some cardboard (tough 4layer stuff) and the blade would still shave. Whittled a stick of seasoned maple and got good 1 inch curls of wood, you can't expect a chisel ground blade to really shine in this department IMO but it did well. I then took it in icepick grip and stabbed it hard into an anchored 2 x 6 (pine) HARD about 8 - 10 times. No play in the lock or the pivot I spine whacked it a couple of times and I discovered something interesting, the liner flexes alittle but the lock doesn't move. What does this mean? Well, it may mean that the liner is actually more secure than if it didn't flex. I icepicked it hard again into the pine and worked the handle back and forth while the tip was embedded 1/2 inch into the wood and sure enough, with enough effort the liner bends slightly and springs back without moving from it's location on the tang. So the final verdict in my case is that the Emerson CQC7 is more secure under hard use than I gave it credit for and I admit some wrongfully wrongful wrongness in my original post in this thread. BTW I tested the Benchmade 710 side by side with the Emerson this morning and it did not fare as well. Save that for a different thread. Hmmmmm, I always liked the look of those Commanders
