Well, my large Sebenza has been a normal rotational carry for quite awhile now, and it's been used regularly (mail, boxes, branches, etc.), and some would say abused now and again.
For those who may doubt, the lock is ROCK solid, and the edge isn't fragile at all.
Lock and edge testament:
As some of you may remember (and got a chuckle out of), around Christmastime, rather than going to fetch the saw to cut off the bottom 1" or so of the tree, I figured I'd ventilate the bottom of the tree trunk with a few well-placed holes...from the Sebenza. As it turns out, the first two full-strength stabs were about 1" deep into the tree, no problem. Lock 100% secure. Then arose an interesting "occurrence." The netting that was on the tree then slipped a little, just as the right hand was plunging earthward with the knife. Did I mention I was holding the netting-encased trunk with my left hand? Anyhow, you can probably see where this was going, but for those lacking the vision, I managed to impale my left hand (dare I say stab?) right between the thumb and forefinger. And the lock held 100%. And the edge was unscathed. My hand... well, that's another story. It went in about 1.25" and almost came out the palm-side. No pain at all. Just made a different sound as it went in. "thunk, thunk, squish...hmmmm... honeeeeeeyyyy- get the keys."
Cost: 1) 11 external, 2 internal stitches (to tack down the muscle, which was sticking up over 1"); 2) 5 hours in the ER; 3) 2 weeks bandaged and lots of worry about nerve damage (none, no ligaments, nada- missed all the "good" stuff).
Benefits: 1)I didn't have to put up the tree ;-) ; 2)I now KNOW that the Sebenza lock is about as strong as a folder can get; 3) tree sap isn't usually a good wound sealer; and 4) use a saw
As an aside, the Sebenza has now been placed on short hours (as has everything else (except the mini-Dyad in left pocket and miniUDT, MUDT or WWPocket Pro in watch pocket) as I evaluate my recently arrived Darrel Ralph Apogee. Look for a review in the coming days. And, no, it DOES NOT involve flesh impaling (well not mine!).
