Starting with the standard Stanley utility knife blade we have used minimalist design principles to come up with the smallest and lightest utility knife possible.   Choosing a ceramic (ZrO2) blademakes this tool lighter and rust proof for life.The ceramic blade is harder than steel and retains its sharpness far longer than existing steel blades.

I have a Kickstarter Campaign where you can purchase this innovative small ceramic knife.

Who is this made for?

The trapezoidal utility blade is one of the most commonly used blades in the world. In North America it is estimated that 40% of all homes have one or more blades and over 60% of businesses use them. Obviously a micro ceramic knife cannot serve in all general purpose tasks due to size and the brittleness of the super hard blade. The long lasting sharpness of a ceramic blade and 100% corrosion resistance does make this a better tool for small tasks. The size and lightness makes it possible to have and available where a full sized utility knife would not. If you carry a wallet/purse, backpack, keys, or have a pocket in clothing this microknife can be safely carried and ready for use.


A minimalist design for a truly functional micro knife using existing ceramic blades. Every day carry size to be available when needed.


Details

Size:

Total length 2.5” with ceramic blade inside.

Material:

Zirconium Dioxide, Ceramic

Thickness:

3.5 mm. under ¼”

Weight:

6.5 gms or .23 oz (= 3 pennies)

The ceramic 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). Testing has shown that in cutting abrasive materials such as cardboard the ceramic blade will retain it’s edge about 20 times longer. The Zirconium Dioxide ceramic 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.

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.)
