A nifty little cutting tool for flute is being advertised in the States for under US$15.00 for the 4 mm version.
Alternatively, under US$50.00 for the 10mm version that includes a replaceable head.
The Coro Claw is a hand held flute knife that the makers say can score or cut a +2metre sheet in about 3 seconds, or trim a print exactly along a flute. The scoring enables you to put bends in the sheet in order to make a stand, display, box, etc.
The 10 mm version is called the Coro Claw X. It uses a new patent pending blade design that is "cutting edge" !!
