How to Sharpen an Obsidian Knife Blades?

Obsidian Blades are made from a variety of materials such as metal, titanium, plastic, ceramic, glass and obsidian.

It is a naturally designed glass that can be crafted to a considerably sharper cutting edge than steel blades. The substance is even used in some sports knives. If your obsidian knife blade has been worn down and could use sharpening follow these easy steps:

  • Stand in front of the kitchen counter and place the sharpening stone vertically on the countertop.
  • Place the obsidian blade flat on the stone, placing the length of the knife at a 45-degree angle to the stone.
  • Take the handle of the knife, with your index finger along the blade’s backside.
  • Lift the blade’s flat side surface off of the stone at a 20-degree angle, but keep the cutting edge over the stone.
