I'm thinking the quality of the hafts, hilts, and shafts of weapons and tools should either imbue a bonus or a penalty, depending on how high or low the quality of craftsmanship it; nothing major, mind you, +1 and -1 or +2 and -2 at most.
When you think about it, it makes a bit of sense, seeing as a low-quality hilt wouldn't be comfortable to hold, and if it's not comfortable to hold then you're not gonna be able to use to its fullest potential.
