we must be looking at different pictures or have different ideas what
that is. the only thing behind the lever is the arm that holds the
lever. That doesn't provide any clamp that I can see.
Look at this for what a clamping bar is:

and moves with the blade. It contacts the sheet being sheared before
the blade does. The spring tension holds the sheet in place as the
blade makes it cut. It makes for a very high quality and precise cut.
