These 45- and 90-degree squares are so precise that they come with a certificate of accuracy that guarantees each one has an angular maximum deviation from nominal of less than 0.001 inches at any point along the full length of the blade. Set cutting tools to the perfect angle, while a support lip holds the tool on the edge of the work piece for marking and layout. Combine this with modern, functional styling and you've got a tool that is worthy of the most prominent location in your display cabinet.

Also, I tested their claim of squareness and found that it is dead on.
A perfect tool
Did the reviewers not look at the picture and realize the handle grips, with obligatory screws, are obviously attached separately to that single monolithic blade/body? With conventional two-piece designs, the often separate grips are attached to a separate handle attached to a separate blade.
For truly precision results with this tool, only the blade surface (not the handle grips) should contact the work material (same with the Starrett 20-6 and similar precision designs). This requires a minor adjustment to the average work flow (the blade tilted slightly with the inside of that blade used for marking). If extreme precision is not needed at any given moment, the tool can be used normally (blade flat with handle grips against the work material). This latter use will often still provide above average results with these precision-oriented tools.
I have compared this square to the much more expensive Starrett 20-6 owned by an associate (a fanboy unwilling to accept anything without the Starrett name stamped on it) and found no difference in either accuracy or workmanship. The Starrett 20-6 uses the same single blade design, with only the blade (not handle grips) used for ultimate precision.Read more ›
I know that this is one of the best squares I've ever own and will own. My next purchase will the one with the 45 degree angle.
So far, here's some of what I've squared, in addition to just 90's on wood:
-Table saw blades after angle cuts
-Initial table saw arbor adjustment (parallel to miter slot), subsequent fence adjustment for same.
-Radial arm saw table to blade after new top installed
-Drill press arbor to table
-Mortising attachment for drill press (2 planes there)
-Bandsaw blade to table (check for tire alignment AND table alignment to blade) VERY necessary for Resaw or veneer.
So why do I use this square? Easy. The less error in my machinery, the less cumulative error is transferred into my substrate. The accuracy marked on wood is a nice aside and it's great to have a square that's fit for "double duty".
The only draw back to this tool is the price. In the end, its just a piece of aluminum, anodized and all shiny, and it probably cost 8 bucks to make. I feel a lower price would be more appropriate, but in this case you certainly get what you pay for.

I got this square because I wanted something a little shorter than my 12" Starrett square, but also one that had a ledge so it could sit on the edge of a board. Read morePublished 3 months ago by Matt
Absolutely confident when using this very hefty square. It is without a doubt, very well machined. Would have been even better with an integrated measure.Published 3 months ago by 1strail
A true square. If I need to get my fence true to 90 degrees, I use the Incra. If I need to verify a square cut, I use my Incra. Read morePublished 10 months ago by Tunero
