Some basic items with durability can be repaired by combining two items of the same type and adding up their durability.

This doesn't spoil the game balance, and I'm tired of 10 bug nets with 12% durability lying around in my base. If balance adjustment is necessary, It's fine that have a certain percentage of durability loss when combining. In that case, I'd like a bonus to reduce the loss for Wilson and Winona.
