Tips for use
For best results use a drill on a fast setting and cut through the foam very slowly. Use a 25% detergent, 75% water lubricant to provide a smoother cut and reduce friction. The large cutter can also be used by hand, but performance is reduced. The cutters come pre sharpened, so try and drill on to a soft surface such as rubber, card or foam to keep the cutter sharp - they can be re-sharpened if required. Use a bodkin or needle to gentle remove the foam without damaging it.
Cutting your own foam saves money and ensures you get the colour, size, quality of foam and cut you desire. Meaning that the proportion of foam on a given fly is matched for perfect presentation.
