Great and necessary tool!
I donโt know how I lived without it for the past couple of years. Well worth getting it , even if itโs just to learn that my โflatโ kitchen table that is used to level my cutting boards before planing wasnโt that flat over the whole length, but now I know which parts of the table I can use for flattening.

Reasonably priced and very usefull
This is my absolute go to tool when trying to make sure something is flat. I have used it numerous times and it is beyond useful. It is straight and sturdy, surviving in my chaotic shop without issue.

High Quality 39" Aluminum Straightedge That's Lighter, Costs Less than Steel
Quality product shipped in a protective case and delivered in prestine condition. Excellent choice for interior trim carpentry tolerances without breaking the bank on steel. Aluminum is lighter while still maintaining high quality. Would recommend and buy again if needed.

Well made straight edge
It is a stout straight edge. It is flat, straight and has a bit of weight.

Pretty good for the price!
Pretty straight at a good price; note that the surface edge is flat but there seems a little bend. Handle carefully as it is not the harder material (steel) typical measuring instruments.

Perfect for testing engines
Bought this to test cylinder head straightness, ships quick and it's well built. Only gave it 4 stars cuz I wish the edges were sharper, so I can confirm if I'm sitting the ruler straight on the head and not tilting it sideways.
