Blue Spruce Mini Square

The Blue Spruce Mini Square is designed specifically for woodworkers who need a precise, easy-to-use tool to check the edges of chisels and other cutting tools. Traditional squares are often too long to clear handles or too narrow to align easily, which is why the Mini Square was developed with inside dimensions of 1-1/8” x 2”, making it perfectly sized for tool inspection.

Machined from durable aluminum, the Mini Square is lightweight and safe to use on your tools—it won’t chip or damage cutting edges. The green anodized finish ensures any gaps are clearly visible, giving you accurate readings every time. Its compact design allows it to fit in your pocket or its custom fitted MDF case, keeping it ready at your workbench or on the go.

Every Blue Spruce Mini Square is milled and inspected to tolerances of ±0.001” per foot (±0.0085°), guaranteeing precision and reliability. If your Mini Square ever falls outside these tolerances, return it for immediate repair or replacement. Perfect for professional woodworkers and hobbyists alike, the Mini Square combines accuracy, durability, and convenience in a tool you’ll reach for again and again.
