Had a bit to drink at work tonight, took the nmfbm out to destroy stuff.
Took some hacks at a 5 gallon bucket (similar to the home depot buckets).
It ate through the bucket easily, like nothing, but the belly towards the tips, seemed to have chipped. Ugh, gotta bring out the coarse stones...

I'll add pics of the bucket later, can't get pictures of the chipped edge with my phone.
 
That is odd --- it really shouldn't have. Post pics -- lets see it when you can.
 
Just four whacks? No metal anywhere on that bucket, so how big are these chips? pls
 
I once cut paper with a MOAB --- the blade broke in half. Lol --- just messin ;)
 
Haha! ^

Sorry guys, I took over a dozen pictures but my camera phone WILL NOT macro.

I don't have any other camera either.

But it is a triangle chip, with rolling on the sides of it. It's very small, but was not expecting it to chip on hard plastic.

I did not hit concrete, it wedged in the bucket.
 
I'd wager that what damage you are seeing is a result of lateral forces caused by the wedged blade in the bucket, probably had a bit of weakened metal at the edge that needs to get ground away. Sounds like you could resharpen yourself if you'd like, no need to send it in unless you are unable
 
Nah I'm not going to send it in, I'm going to dig out my 400 1000 and 4000 grit and reprofile it.

I will sa, this thing rocks!
 
You will likely notice the edge holds up better after sharpening it up, the weakened metal was likely a product of overheating the apex just enough to soften it from grinding on power tools (belt grinder) and the heat that comes along with it. As soon as that little bit of weakened metal gets ground away, you should be good to go.

Awesome! Yeah so far I only polished the edge because it was reflecting some light.

Soon I'll put it through some coarse stones.

These things prefer to be obtuse? During polish, i had to nearly hold the blade 40 degrees to get the edge...
 
They come factory with cinder block chopping edge geometry, I'd at least advise taking that number in half to increase penetration and cutting ability for everyday use (not destruction testing).
 
Ok, tried to use a 60x scope but my camera won't focus.
In this picture, the chip occurs where it's brightest on the blade.
You can see the few chips.
 
Yea --- I would guess Red Angel Dragnet nailed it with the weakened steel --- after sharpening it should be fine. If it continues to chip -- contact Busse right away to see what they say/recommend.

I plan to thin out the edge just a little, I'm not expecting a paper slicing knife, more of a competent chopper.

I'm just jealous that you get to drink at work...

It can be fun, but sometimes too many drinks show up on my chopping board, I have to, don't hate me, throw away many drinks...
I do work with super sharp knives and like to keep my fingers!
 
I take the edges to 19.5 degrees each side with a clean mirror polish edge. I also thin the shoulders a bit to let my knives bite deeper. There's nothing that I feel my knives would be unable to do at that angle.
