Product Information:

This coarse pocket-sized diamond sharpening card encourages keeping every edge tuned to its utmost. Using only water for a lubricant, knives can be drawn across the stone at a 20 degree angle, while router and other bits get their flat sides sharpened. The monocrystalline diamond structure of this DMT card is exceptionally strong and doesn't break away under use. One of the medium or fine cards in a shirt or apron pocket can take a lot of the tedium out of caring for edged tools. Cards are 2" x 3-1/4".

  • Monocrystalline diamond particles
  • Coarse 325 grit card 2" x 3-1/4"
  • Water used as the lubricating wash
  • Great for knives and router bits
  • Small size make carrying these in an apron pocket very efficient

    Comments about DMT Credit Card Diamond Stone, Coarse :

    I've used mine for all sorts of things, from flattening smaller sharpening stones to straightening knife edges/quickly touching up hard-use knives to flattening tool surfaces before polishing. I've even used it to flatten my King 6000 water stone. I plan on buying another to toss in my hiking equipment, just in case. Works fast, works consistently, and works well.
