Washita stones are mined in the Ozark Mountains in the state of Arkansas in the United States. Washita stones consist of silica, but unlike synthetic abrasives, do not consist of individual abrasive grains of the same size. Washita quartz structure consists of fused crystal grains of different sizes.

Washita stones are universal and can be used to sharpen knives of any steel.

Washita stones can be of the following types:

  • Lily White - top-grade hard white stone without inclusions for fine sharpening
  • Rosy Red - high-grade soft or hard stone with red veins
  • #1 - hard stone for fine sharpening; stones may have little defects
  • Regular - soft stone for coarse sharpening; stones may have defects and inclusions

Washita stones should be used with any lubricants: refined olive oil, oleic aсid, Dan's mineral oil or water.
