Sharpening can be a messy business. Whether you use water stones or oil stones, there’s a slurry of lubricant, stone debris and metal cuttings that gets everywhere. While your hands and tools are covered in this stuff, you still need an accurate, reliable way to check the edge to make sure it’s perpendicular. Here’s the perfect answer. Blue Spruce Toolworks new one-piece Sharpening Square. Most squares are too large to be used with the tool in a honing guide. The compact design of the new Blue Spruce Sharpening Square usually allows you to check the chisel or plane iron while it’s still in the guide, saving you time and effort. And, as one solid piece of stainless steel, water, oil and dross just wipe right off.
Unmatched machining accuracy. This corrosion resistant stainless steel square is cut in a wire EDM machine. If you’re not familiar with the term, Wire EDM is a non-contact machining process using an electrically charged tiny wire and insulating fluid to make remarkably accurate cuts. We’ve designed the profile with relief cuts in the bevels, protecting the edge while still giving you an accurate reading. And, we made the square just 3/32" thick so it’s easier to get proper alignment.
To celebrate the introduction of this new tool, we’ll be offering two versions, the standard and a limited run version with a jeweled (engine-turned) finish. The standard square has a satin, bead-blasted finish to reduce glare. The limited run version has a finish reminiscent of accents found in classic watches, fine tools and dash trim from high-end autos during the 20’s and 30’s. Jeweling is a painstaking process requiring a skilled operator and lots of patience. You can get the standard Sharpening Square anytime, but the jeweled finish version is only available through the end of the introductory promotion, which ends December 7, 2021.
Whether you choose the limited run version or the standard, you’ll get unmatched precision in a tool that’s perfectly sized for its job and made from material that stands up to abrasive residue and damp conditions. The Sharpening Square is 2-3/4" x 3-3/16" x 3/32”.
