It has always been a plastic vise. It was designed in plastic to keep the price down. The metal parts are the ball bearings (the race for the bearings probably are metal also but I have not taken it apart to know), Jaws, stem shaft and screws. I can not remember what kind of plastic it is. More like a phenolic than what most people think of as plastic. Quite stiff and rigid. Very stout.
Most plastic things I don't care for because they just don't stand upto hard use, abuse and age. This vise has what it takes.
The only plastic part that might be able to wear would be the cam lever mechanism. It has not worn any.
The vise jaws work off a falcrum principal. The instructions say that you can apply so much force you can break the metal jaws. I have managed to not apply that much force though.
Thanks for the link. I forgot about this third party base that you can now buy.
