Mill, plasma cutter or waterjet. Or 3dprint? Worth exploring patents if you want to pay for your new CNC investment. The basic idea for this device has got to be in a patent that is past it's 17 year expiration. They may have later patents on improvements that can be avoided if you know what they are. Obviously you can't sell it with a name that is naything like the "Kantwist" trademark. Personally I'd market it as a kit requirin "Pin It")

Like find whatever shape stock for the jaws you want or even blanks you can machine or shape yourself.
