Within days of getting my Basic 5, it had been used as a baton to split kindling (no big deal), pried apart a log that was partially rotted, stabbed repeatedly into a 2x4 torquing it out sideways, and limbed a small tree. You can tell I'd been reading Cliff's reviews.
Since then, the knife has endured more of the same, along with breaking bricks with the spine, digging up a few big rocks in the back yard, being used as a prybar to break banding material, open crates, and of course, dismantle pallets.
For ~15 months it has been my "go to" knife when I shouldn't be using a knife for the task at hand, my beater, and improvised prybar.
Before it's last sharpening, I was playing with it, and using it as a thrower (it actually throws pretty good) to see if it would damage the edge, which was now v-ground and much thinner than the factory bevel. It bit the dirt, and a few rocks several times (I said "pretty good"), along with being thrown forcfully into an oak tree-target was a big knot. The rolled places straightened out with a steel.
I have never seen it chip. It has had several dents and rolls, where the metal was displaced, but still there. The only time I've seen a section of edge broken off was the same night I broke the blade. It had been prying up boards, and sometimes the edge was against nails while I was prying. I think I mentioned in the other thread, that sometimes I would wedge the knives between the boards, and stomp on the handle to split them apart. Can't think of any other knives I could even imagine doing that to.
It survived far more abuse than I've given any knife, and I intentionally used it hard.
So it broke. I've broken wrenches, shovel, axe, and sledgehammer handles in use, bent prybars, and all kinds of other stuff. The Busse held up far beyond what I would have ever expected a knife to handle.
Other than a Rinaldi TTKK that I want, I have no desire to buy any more fixed blades except Busses-because hard use blades are the only niche that is not filled in my knife "accumulation", and I hope noone will hurt me for saying they're the #1 hard-use knives in the world
