The brittle is not an issue of the repair. people who use splinter know how often they need to repair, brittle is an issue where this item will die. It will wear down to 150 durability in a months time, and then your repairing guaranteed every battle, your forgetting, the durability gets worse, and eventually you got a 0/30 dura wep. Since you cant pof it, cant keep the dura nice and high where ya dont have to stress
