  • High Quality 39" Aluminum Straightedge That's Lighter, Costs Less than Steel
Set name: 38 Inch Straight Edge
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.

  • Reasonably priced and very usefull
Set name: 50 Inch Straight Edge
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.

  • Its the right weight and perfectly straight for wood working.
Set name: 38 Inch Straight Edge
The "POWERTEC 38 Inch Straight Edge" is a tool that is, according to the test I use for woodworking tools, perfectly straight. It has a nice silky-smooth finish, isn't going to rust and is easy to handle. Not only that, but it is stable sitting on its bottom edge and within my rather limited budget. I should have got one of these for my shop decades ago. ... show more

  • A great straight edge
Set name: 38 Inch Straight Edge
This is a great straight edge and for a great price. It's dead flat and solid. My only complaint is that the solid silver design is hard to see where it meets the surface of whatever you are using it against. A bit of paint to add some contrast would fix that.

  • Great and necessary tool!
Set name: 38 Inch Straight Edge
I don’t know how I lived without it for the past couple of years. Well worth getting it , even if it’s just to learn that my “flat” kitchen table that is used to level my cutting boards before planing wasn’t that flat over the whole length, but now I know which parts of the table I can use for flattening. ... show more

  • Well made and fair price.
Set name: 50 Inch Straight Edge
This is a very nice straight edge. Has metric and standard rules on it that was important, unfortunately I needed this to cut material with and it does not have a machined edge that works well for a razor blade and cutting (they do not promote it for this application) and I needed to return it. For the price and quality this is a well made straight edge. ... show more

  • Straight, reasonable price, and stand up
Set name: 50 Inch Straight Edge
You can use a ruler for a straight edge, but it doesn’t work as well because this power tech straight edge will stand on edge. So I realize my workbench is not perfectly flat. This thing is beautiful. It has inches in centimeters. And it’s long enough to be useful.
