Dan's Whetstone Arkansas sharpening stones are used for sharpening knives on Hapstone and KME knife sharpeners. Arkansas stones are made of novaculite, a naturally abrasive material of high density.
Arkansas stones are mined in the Ouachita Mountains in the state of Arkansas in the United States. Arkansas stones consist of silica, but unlike synthetic abrasives, do not consist of individual abrasive grains of the same size. Arkansas quartz structure consists of fused crystal grains of different sizes.
Dan's Whetstone offers Arkansas stones of the following types:
Arkansas stones should be used with one of these lubricants:
Arkansas stones usually have moderate variations of shade and color. This is normal for natural stones and not treated as a defect.
Arkansas stones do not require any preparations. However, Black and Translucent Arkansas stones may be extra lapped by customer.
Possible preparations for Black and Translucent:
Translucent and black Arkansas stones have the same density. They are of equal value as ultra fine finishing stones.
We are sorry to note that Dan's Whetstone does not sell black translucent stones. The true hard Arkansas from Dan's combines features of hard, translucent and black Arkansas. True hard is overpriced so buying black Arkansas makes more sense.
Grit terminology is not applicable to natural sharpening stones, including those composed of novaculite. The behavior of a natural stone depends on its density and how good it was lapped. You can find Soft and Hard Arkansas stones in a Grit Chart, but they are there for reference only.
