Cold Knives

These innovative blades have the longest-lasting edge available today. Specialized grinding and heat-treating techniques are applied to the production of these high-quality blades to ensure that they maintain a tough edge without becoming brittle. Their design was taken from the original UltraWiz® blades. Made in the USA.

The unique shape allows for the removal of glass without removing the moulding. PN1022 cuts under the molding around the back edge of the glass and underneath the glass. Its unique shape allows you to remove the glass without removing the molding. After the glass is removed there is very little pressure holding the molding into the urethane and it is easy to remove without damage. Original Thickness. Made in the USA.

Made with UltraWiz®’s dual-angle sharpening method. PN1000 is intended for use as a starter blade. The cutting area is 3/8" long and is useful when starting your first cut on urethane that is wider than a regular blade. Original Thickness. Package of ten. Made in the USA.

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.
