- 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 saw, drill press, circular saw, router table, etc.). While they are expensive I learned in an engineering class that you have to pay more for better tolerances and the expense here is well worth it over a cheap square. Yet there are more expensive squares out there and the Incras are "guaranteed" so if they are not perfect they will make it perfect. If you purchase these I don't see how you will be disappointed as they are one of the best asset you can buy for quality work.

- Excellent tool
- You do indeed get what you paid for. It seems to be dead-on as my wood joints come out tight. The lip works great for marking boards, and its perfect for tuning tools. Incra offers a lifetime accuracy guarantee on their website, and even claims ordinary drops can't affect the angle. And I drop alot of tools.

- Great Tool- decent price
- I have owned this square for almost a year now, and I find myself using it more and more with each passing project. It, along with most other Taylor Design Group products, is well thought out and has superb machining. I took this tool to work and put it on a surface plate, and it is indeed accurate inside and outside to within .002 along the length of the blade. The part I truly appreciate is that it is as accurate using the inside 90 degree as it is using the outside 90 degree ( or 270 degree, however you look at it :). I routinely use this square to set up all my stationary equipment. To me a square is all about trust. I use this square to set up a tool, then put it away and let the tool do it's job. I own a Delta Beisemeyer for exactly the same reason.
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.

- A square is not always square!
- I once thought that when you bought a square and took it home, it was square. I just got this square today, and I am surprised with its quality and accuracy. I used it to check carpenter's squares, tri-squares, carpenter's speed squares and a precision Starrett branded machinest's square. Each was off up to .010" except the Starrett, which came in a close second this one. Not bad for the Starrett, since it is over 30 years old and has been dropped many times on a concrete floor. The INCRA is better than the Starrett, since the Starrett is rusted and pitted from years of sitting around in the garage shop.
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.
