I don't normally perform the spine whack test as I don't find it to be of very much merit for real world applications, but for the sake of arguement, I subjected my brand new Sere 2000 to this test anyway.
I dawned a double layered, military repelling, leather gloves and held the handle of the knife very firmly between my thumb and forefinger. Then I whacked the back (spine) of the blade a total of ten times on my porch railing.
NO FAILURES to report!!!
Now I know that I didn't attach the knife to a broom handle for extra leverage, but, I did whack the hell out of this knife with all of the force that I dare.
So take that for what it's worth.
Now, on the subject of the sharp thumbstud...
I'm going to have to agree that this knife comes with a fairly sharp stud. I would even go so far as to say that if you had let's say ......fair, womenish, non-working hands, then you will probably end up bleeding on your first attempt at opening this folder.
I fixed this situation on my knife using a jeweler's file to remove the sharp edge. It's perfect now.
The Sere 2000 appears, IMHO, to be a over-built workhorse of a knife that is worth the price. It certainly blows much of the competition out of the water.
So if you are still seeing smoke.......it's probably just from me putting out the fire!!!
