The problem with this arrangement is that as you pull the lever down to perform the cutting action (bringing the two curved blades toward each other), the workpiece has a tendency of pulling into the shear. The bottom line is that I can't ever seem to get a square cut with this thing.

Can any of you inventive souls come up with a jig that could help me out?
