Somehow I had the need to cut a thin sheet of plastic. Due to its large size, use the hacksaw was impossible, but to cut just the canvas for a long time, and breaks it in his hands. Rescued normal gear from the children’s designer “Young watchmaker.” Opav the first of its axis and sharpened needle file teeth, I got a great mini-saw. Then, holding the axle in an electric drill Chuck, I quickly and carefully sawed the plastic.
