A great asset to my shop.: I have no way to test this tool except to use it to calibrate my tools and if the woodworking job comes out perfect then I know this tool was dead on for what I use it for. I have 4 Incra guaranteed squares(5" square, 5" 45 degree, 7" square, and 7" 45 degree) and absolutely use them religiously to calibrate all my tools (table saw, jointer, planer, miter saw, band… More reviews

Avoid this one unless you want scintific accurary , which is 'Over exacerated' when it comes… More reviews

Great, just great!: Look at where the red part meets the gold, there's a lip there. This lip lets you rest the red part over the edge of a board and it won't tip over or move; it's a great feature. Because this tool is so accurate; I don't keep it in my apron, which means I don't use it a lot. However, I mainly bought it to keep my tools aligned, which… More reviews
