What material to make molds

Phil Joines Krum, Tx
>I want to cast some poly resin tools to show the various grinds.

Whats a good material for the molds? Id like to make them in one piece. Id also like to be able to reuse the molds. Plaster of Paris would hold its shape but I dont know how difficult removing the casts would be. It would be easy to remove them from RTV but how well does it keep its shape? Any other suggestions?
