A modern design provides the smallest and lightest utility knife using ceramic blades. Ideal for everyday carry on keychain, wallet, zipper pull, or as part of emergency kit. 100% rust proof in salt water makes this ideal for boating or fishing activities.
A ceramic edge will not curl as a steel edge will when cutting tough material such as kevlar or the new ultra high density polyethylene ropes and lines now in use. The overall size and lightness makes it possible to have the micro knife available where a full sized utility knife would not.
While the standard white Zirconium Dioxide (ZiO2) blades offer great improvements over steel blades we have found that the more expensive “carbonized” ceramic is worth the extra production costs due to increase hardness, strength and sharpness!
1) The ceramic utility blade is the same size as the universally used Stanley blades with the exception that it is slightly thicker. (.8mm compared with .6mm for steel blades) Yes a steel utility blade will fit. The black ceramic blade is made by carbonizing the white blade in a second sintering operation. 50% higher production cost BUT results in a harder and sharper blade.
2) Testing has shown that in cutting abrasive materials such as cardboard the ceramic utility blade will retain it’s edge about 20 times longer.
3) The Zirconium Dioxide ceramic utility blade will cut Kevlar, and other tough materials such as the new “super ropes” and fishing lines better than steel as the edge does not curl and create burrs like steel blades.
4) The ceramic micro knife body is injection molded in two parts. These are electrosonic welded to create the proper tension to hold blade in place during carry but permits in and out movement through thumb pressure. (We tried but were unsuccessful in creating a holder of bronze or titanium materials as the correct tension and sliding resistance could not be controlled.)
Weight of tool with ceramic blade is 6.5 gms or .23 oz (= 3 pennies)
Thickness is 3.5 mm. under ¼”
Total length 2.5” with ceramic blade inside.
