Ruby Bench Stone 4" x 1" x 3/8" Boxed

Ruby bench stones are crafted from sintered crystals of synthetic ruby, making them exceptionally hard and highly resistant to wear. Their superior hardness allows them to sharpen and finish extremely hard metals — including carbide gravers — as well as non-metal materials such as glass, porcelain, and quartz. These stones maintain their shape reliably over extended use, making them a dependable choice for professional jewelers, metalsmiths, and engravers who demand consistent performance from their sharpening tools.

Available in two grits, this 4" x 1" x 3/8" bench stone comes boxed for convenient storage and protection.
