I agree with Cobalt.
Jerry has no idea if the guys who did the regrind did it slowly and carefully to make sure they didn't stuff up the temper or just went flying in like a bull in a china shop so when they decide to chop down the local street sign to show what their reground FFBM can do they snap it in half and cause Jerry to honor his warranty.
Not that I disagree with Busse's Excellent Warranty.....I happen to think it is very reasonable in regards to mods done outside the shop.
If a knife snaps in half while chopping then there is a defect in the blade. Unless ground ridiculous thin, a blade should not snap even if the temper was ruined. A blade will snap if there are hairline cracks in a defective piece of steel. It can also snap if heat treated too hard and not drawn down to a working hardness during tempering (heat treat issue).
A knife's ideal hardness is decreased if heated beyond it's max tempering temperature (approximately 900-950 degrees for INFI in this case). Anything above that 950 range and the RC will start to drop. A softer piece of steel wouldn't hold and edge or cut very well....but it may very well be tougher in terms of taking shock and impact.
