I have a couple suggestions.
Mace - 1 ingot blunt weapon with 1 hand grip (the dagger of the hammer family)
It would be great if the crates had a lid that could be closed, that way if one is picked up with items inside (i use one of mine to hold 1h grips in the store) the contents dont explode everywhere
Orders of more than 10 would be amazing, would save much back and forth work to bring quantities of grips and guards into the store
Add another torch to the right side of the bench, to make it easier to see when assembling at night (currently only a small portion stays bright enough to see metal on the blue of the bench)
