The easiest and most efficient way to round out the corners on a stack of paper is with a corner rounding machine.There are several different kinds of these tools, from small handheld punch-style meant for individual sheets or tiny stacks, to desktop models for thicker stacks, and even floor-standing corner cutters for high volume and thick stacks of paper (as well as other materials).

    • You can usually find the handheld corner rounding punches at local craft supply stores.

    • Desktop corner cutters start at about $120 and can cut through a stack of about 1/2" thick worth of materials. The more heavy duty tabletop corner rounders can handle stacks up to 1" thick.

    • The floor-standing corner rounders start at about $700 and can cut between 1/2" and 4" thick stacks.
