i heard its just a 1 year warranty. what if its after the year warranty is up and the motor pukes? do you end up with an $80. paperweight?
I can see your point there. Though again, I find that the tradeoffs(more forgiving convex grinds, more range of sharpening grits, smaller size, portability) is worth it, at least for me.
I did indeed buy another one, not because my last one burned out, but because it's making horribly loud screeching sounds. I suspect it was because I ran it a hell of a lot longer than 20 minutes in an hour when I was grinding the massive chips(think M&M size) out of my coworker's machete, which was slowed down because the belt was loaded with metal and I didn't have a belt cleaning block then. I haven't seen any other reports of the motor burning out on one of these yet, so I doubt it's a common issue. I do have a Craftsman angle grinder that burned out as well, though I used to use that for sometimes up to an hour nonstop. I suspect motors last a hell of a lot longer if you follow the instructions and don't keep it on continuously for too long. Admittedly the runtime is a bit pathetic at 20 minutes per hour, but that's often long enough for my needs(maybe 1-2 knives per day at the most).
It's not perfect, and I would definitely have to yield to paper wheels if I was ever in the business of sharpening knives en masse like you. But it's, how would you put it, more
flexible?
Could you use paper wheels to sharpen something like a machete and axe or hatchet, too? That would be a nice plus.
If it's not too dull I'd say it's possible. The wheels are only 180 grit IIRC, which may not be coarse enough. Though if you thin the wax layer it might move along faster.
Still, I suppose I should mention that the Worksharp works with larger blades quite well, and I think it would work especially well with an axe or hatchet as you could put a beautiful convex edge on those. Here's one I did on my ESEE Junglas Machete:
