personally, while thinking of whetstones I remembered something my dad once told me that could be implemented in the mod if this is added: to sharpen skates, you first use a rotating tool that I forgot the name of. That is the main part of the sharpening. However, once this is done, there is some metal left from the grinding that may affect your skating. To remove them, you pass a small whetstone or something similar on the edge of the blade, which just makes it cleaner in this case. Here is the interesting bit: if you pass the stone incorrectly, you've just scrapped the sharpening job.

so, to conclude, what if when you put a whetstone, it greatly decreases the chance of negative sharpening modifiers, but there is still a tiny chance that the sword may be scrapped by bad usage?
