Scribble
These are steel reaming broaches that I use to enlarge the hole of a clock or watch hand so that it may fit onto an arbor or canon pinon. I use a pin vice that clamps on via an adjustable chuck to hold the broach, For small watch hands I have a special vice that has an assortment of different size holes to pick from. The hand is placed over the hole needed for sizing then I screw down the vice so the hand will not move once I start to ream with the broach.
