Spyderco bench stones are perfectly flat and are wide enough for effective honing of large knives, chisels, and wood working tools. This ultra fine grit model comes in a rigid black polymer storage case with rubber feet for table top use. These stone like other Spyderco ceramic stones should be used dry without lubricants or oils. Over time the stones will become clogged with metal particles and effectiveness will be reduced. To clean, just scrub metal particles from stones with plastic scouring pad and abrasive powdered cleanser. Brand new directly from Spyderco, Inc.
