Whetstone Mahogany Quarry PDF Print E-mail

Whetstone Mahogany QuarrySince the Whetstone property was purchased in 1990, this quarry has been developed into our "project quarry" to meet the demands of even the largest projects.

Since switching to wire saw production its yields have increased dramatically. Of all our quarries, it shows the greatest potential for both premium gang saw blocks and smaller economy blocks perfect for project production.

Like our other Dakota Mahogany quarries, Whetstone's impressive test data make it ideal for outdoor use in any climate and for heavy foot traffic areas.
