Is it possible to sharpen the round rotary cutter blades used for cutting fabric?
It is possible, with a little ingenuity. I sharpened a pizza cutter wheel by removing it from the handle and attaching it to my cordless drill with appropriately sized hardware. Used the Universal Support so I could comfortably and accurately get the right angle and control. Started up the T-7 and the gave the drill just enough speed to accomplish what I set out to do.
Hope this was helpful?
