I once bought a used 80 ton hydraulic press from Levi's. It was used to cut blue jeans, cotton fabric dust everywhere in it. It used maple plywood and die rule cutting dies that could produce 1000's of jeans pieces a day, (polyester/cotton fabrics are a bitch to cut). The dies could be swapped in a few minutes and rebuilt in about an hour with simple tools. The cost of the dies were about $1000 US and could last up to a year.

Those hand operated cutters are fine for simple items made in small lots, but you want to make millions? They are useless.

*I rebuilt it to cut sandpaper discs and sheets using similar die rule dies that could cut 3000 to 4000 pieces per rebuild.
