Yes sir, Mancini has them. You clamp in onto the torsion bar with the tang facing down. Tighten it up on the bar and then strike the tang with a hammer. I have one somewhat similar. I always put a block of wood in front of the tang, because I don't like hitting the tool directly. You sound like I am. When I need a tool, I buy the thing. I don't care if I only use it one time. If I ever need it again, I have it. Here's the link to the Mancini version. Very reasonable, too.
