Mike!..Just saw the ad for the electric DRITZ scissors on your site. I’ve used a version of those for a few years and love 'em. (they cut like 'butta). I highly recommend 'em. You get that smooth continuous cut. In lieu of those, if you’re away from juice (electricity, that is -and don’t have rechargeable) - “incredible scissors” - like two bucks at walgreens! They’re sort of tin snips. I have used them to cut zinc photoplates for my artwork ! they actually DO cut beer cans -just like on the thin box they come in. Fiberglass cloth is a piece of cake! So, if you want to get a positive cut without the fear of wrecking an expensive pair of scissors, give these a shot. You never need to sharpen them. TWO DOLLARS !
