well testors i think it is makes a silicone molding kit. you could use that as the mold and then the hard part getting the wright kind of castable rubber . could be done at home , time would be the big thing .
a person could also press the handle in to soft wax and make a plaster copy . then get some low melt hobby metal like type 160 or 280 and make a metal mold . set up your mold and make them with a castable rubber . would be like making parts for model rail road lay outs just bigger :shrug:
ya i think i read way way to much :doah:
