Review: Best Price and Quality - I needed this set for a small art project I had. I mainly got it because it had the best price. I am impressed with the quality of the set. It comes with large right triangles (set squares) and a triangular scale. All 3 pieces are of high quality. The set squares are thick, and hard to break. They are 30-60 and 45 degree triangles. The 30-60 one is graduated 11"x6" and the 45-90 one is graduated 8"x8". There is a protractor in the middle of 45-90 triangle which is pretty cool. The scale is also very sturdy. It will not break. It seems like the prints on it are permanent. It's an architectural scale and it's in imperial units. Over all I am very happy with this product and I recommend it to others also.
Review: Here’s Why I Gave This Product 5 Stars - I like this product very much because of the unusual, and very handy, innovative features “built in.” I admit that my training in mechanical drawing was many years ago. I’ve retained the T-square and angles that I used at what’s referred to in the U.S. as a “technical high school,” But doggone, I’ve misplaced them. I bought the product under discussion because I’m drawing a plan for a product I hope to manufacture. The innovative features I mentioned include “rulers” with imperial measures on the edges of both the 30-degree and 45-degree angles. Other clever features include a simple “French curve” cut into the middle of one angle and a protractor cut into the middle of the other angle. A separate triangular, scale ruler also goes with the set. None of the above features are to be found in my old antique set, nor in any other set I’ve looked at. I consider them unique in my limited drawing experience. Very clever, too! You get four drafting tools for the price of two. From a practical standpoint, the “extra” features save motion and time. One does not need to reach for either a separate French curve or protractor. They are already on the drawing board! As far as durability is concerned, I think they are adequate for my purposes. Time will tell. I’m inclined to think that any really detailed mechanical drawings required by anyone are going to be done on a so-called “Computer Assisted Drawing (CAD)" program these days. While hand-done drawings still fill a niche, they do, after all, represent a pretty ancient artistic skill set. Who cares! They’re fun to do! You can easily see the French Curve/Protractor/Rule features mentioned above in the manufacturer's illustrations on desertcart.
