I have a set of USA Wiss pinking shears from the 60's. I filed and stoned them trying to maintain the original 5 degree angle. The edges are clean and sharp. They cut paper and terry cloth very well, however when I try to cut polyester aircraft fabric they only chew and wad. I tried lapping them by applying lapping compound and working them open and closed. This made then feel smoother operating but did not improve the cutting action. I have adjusted the pin and applied pressure to the blades by squeezing them together but no improvement. Should I change the grind angle or give up and buy a new pair? Thanks, Danny
