I received two Emersons in the mail yesterday, a 2000 Commander SF and a 2000 Mach-1 BT. The first thing I do when I get a new Emerson is disassemble it, clean it, reduce the tension of the second ball detent, lube it w/ Militech-1, reassemble it with lock-tite on the pivot screw, adjust the tension and let the loc-tite cure. I noticed the difference in size of the stop pins on the Mach-1 vs. the Commander. So I broke out my digital calipers and started measuring.
This is what I found:
Commander; .123" diam (1/8")
Mach-1; .185" diam (3/16") a 50% increase.
I thought why would a knife WITHOUT the wave have a stop pin that is 50% thicker? It seems it should be the other way around. [John - what is the diam. on a 98 Commander or ES-1M?] I mean, the wave opening puts alot more stress on the stop pin. Then I stared assembling the knives simultaneously and I noticed that the Commander's blade barely clears the stop pin, so a larger diam. pin would necessitate moving the hole location, which means changing the CNC programs of the liners and the scales. Not cheap to do.
I then measured a CQC7B-Wave, it's stop pin is .185". SARK - .185". Mini-7B - .185".
So, I think the Commander's ONLY weakness would be the stop pin. It would be nice to have a thicker one, especially if the Commander's pin is subject to a higher failure rate than the others.
Any thoughts guys?
BTW, Both knives are perfect, NO stripped screws, NO rubbing liners, excellent lockup, and they even had crushed boxes!!!!
