Upgraded worker hamers

my idea is pretty simple, like the upgraded clothing that the harthlings can ware i think of an upgraded axe and/or pick and/or hammer made by the blacksmith that will give the harthling wielding it a speed bonus in the job that the tool is for for example if set harthling is wielding an upgraded hammer he/she will build faster (pick for mining and axe for harvesting) :tools: :hammer_pick:
thanks for reading my idea
