Complete Diamond Sharpening Experience

The SBS has been meticulously developed over four years and represents the most complete sharpening package available globally. Properly sharpening tools, whether a ¼” bevel edge chisel or a plane iron, involves essential elements all included within the convenient SBS canvas carry/storage case.

Set Contents:

  • A high tolerance, machined single platform with three grades of Diamond Stone: 300#, 600#, and 1200#
  • Three magnetic leather strop covers—two different leathers, firm and soft
  • Three uniquely formulated grades of Polishing Wax: 1800#, 2500#, and 5000#
  • A 30ml bottle of fully synthetic diamond lapping fluid
  • Diamond Stone Cleaning Block
  • All housed in a bespoke, tough Canvas Storage Case

Ease of Use: Sharpening Simplicity

Compared to traditional double-sided 8″ diamond stones, the SBS is ready on your bench, instantly offering three grades of diamond for sharpening. It also features three leather-topped magnetic protective covers in two grades of leather—firm and soft—enabling three-grade sharpening followed by three strop finishing without moving from your work.

Innovation in Sharpening Technology

The SBS is the first 3-grade 8″ diamond sharpening stone to include easily replaceable surfaces, built-in leather strop covers, a non-linear diamond recess pattern for superior swarf removal, and a base larger than the diamond surface for improved stability.

Stropping Versus Waterstones

While many debates exist over the best sharpening methods, our decision to include a stropping option focuses on convenience, cost, space efficiency, and cleanliness. Regular maintenance of waterstones, which requires additional equipment and messy storage, does not compare to the streamlined and tidy process offered by our strop system.

Craftsmanship and Quality Assurance

Made in our UK factory in Salisbury, Wiltshire, each SBS undergoes 11 different quality assurance tests, ensuring that every stone meets the highest standards.

Very solidly built, and easy to use. When sharpening isn’t convenient, it doesn’t always get done. This solves that problem with style.

Robert (PopPop) Walker (verified owner)

Sharpened several chisels but have not done a plane blade yet. So far, very satisfied. I have always used water stones but the diamond stones seem to be much better.
Bottom line – I’m very happy with my SBS sharpening station.
Thanks, MPower
