What is a post vise?
A post vise, sometimes called a leg vise, is a vice that is shaped a little different than most vices. A post vise is designed to be mounted on a post instead of a table. There is a leg that extends down to the ground. The vice can be used for hammering on metal and the shock of the hammer blows goes through the leg to the ground. This is a very useful piece of equipment and if you can find one, I recommend you get one. Here is a picture of a 6 post vise that belongs to me.
