The Rockwell RK9000 Jawhorse is an amazing combination of vise and sawhorse. Rockwell describe it as the ultimate job site workshop, but what it is in reality is like having a second pair of hands. It’s impossible to list all of the things that you can use the Jawhorse for – it can replace your workbenches, sawhorses, clamps and bench vises, and allows you to do jobs single-handedly that you used to need two people to do.
