Rotary Cutter Blades 60mm 5-pack By Cesdes Fits Universal Fabric Cutting Tools By Olfa, Fiskar, and Ergonomic Design for Crafting, Quilting, Sewing, Paper, Leather, Cardstock; Durable SKS7 Metal

SKS7 metal is a high carbon steel with Tungsten and Chromium added enabling the steel to be made thinner (for a shaper cutting edge) and stronger (for touchness so the cutting edge is retained). This is the metal most often used with hack saw blades. The tungsten increases wear resistance while chroium increases wear resistance, hardness, tensile strength and corrosion resistance. Our care for the blades: closing them between cuts, carrying them in their case with the light oil film between them to better enable smooth sliding and protection, checking the surface hidden beneath our cutting for any obstructions (pins, seam gauge, or a dirty or grooved cutting surface) can and will extend the life of the blades. These blades fit OLFA, Fiskar, and contour ergonomic designed cutter tools. SKS7 metal enables sharpness and edge stability. Create your next master piece in crafting, quilting, sewing, paper craft, rug making or leather crafting. Convenience in your studio, workroom, office or home. Thank you for considering CESDes.
