Made with UltraWiz®’s dual-angle sharpening method. PN1004 has a cutting area that is 1-1/2" long. We do not recommend using this blade for initial cuts. Use a shorter blade to make your first cut, then go back with this blade to make your final cut. Especially useful where urethane is very wide, such as corners and along the bottom. Original Thickness. Package of ten. Made in the USA.
