Woodpeckers’ diminutive DelVe square packs a big punch. It has well-thought-out features, and its small size makes it the perfect choice for many tasks.

The blade of the square is not centered on its base, resulting in a 3⁄8-in. offset to one edge and 1⁄4 in. to the other. This allows for simple and precise layout of 1⁄4-in. mortise and tenons on 3⁄4-in. stock. Holes are drilled at 1⁄8-in. intervals along the blade’s 90° edge, useful for scribing parallel lines. The various dimensions of the square make it perfect for accurately adjusting a router depth stop to either 1⁄8 in., 1⁄4 in., or 3⁄4 in. Similar to what you’d find on a speed square, the hypotenuse is marked at 5° increments for scribing angles. The 90° edge is perfect for ensuring sawblades and fences are perfectly square, and the 45° edge can be used to dial in mitered cuts on the tablesaw or miter saw.

The DelVe Square is machined to very high tolerances. Its anodized aluminum body is laser-etched, making it robust and accurate. The square was originally offered as a one-time tool opportunity from Woodpeckers, who retired it in 2015. However, popular demand has led the company to add it to its catalog as a regular offering. It would be a fine addition to any workshop.

Veritas Micro-Adjust Wheel Marking Gauge

The adjuster runs through the beam from a small knob at the back end right to the cutting wheel, which moves in and out as you turn the knob. This arrangement works well but makes adjustments a two-handed operation, requiring a little more effort.
