EditBrass Scrapers
Do not order beryllium copper for use as a scraper, it is too hard. It is best to buy brass bar stock and grind it to a chisel point. Have plenty available.
When purchasing, specify "Brass" not "Beryllium Copper" putty knives for die and screw clean up work. Beryllium Copper putty knives are marked Be Cu on the handle or blade and are harder than steel and may scratch the polymer contact surface.
