Shinwa Sokutei ANGLE SCRIBING SQUARE (62081) (Japan Import)

great tool, who knew something so useful for cutting 45 degree angles existed. I used it for glass

Perfect size and accuracy.

Helpful tool but seriously when am I ever going to need 2 right angles or a parallel line 6 inches apart.

Excelente producto, infantable para aquel que trabaja en carpinteria

I wanted a Japanese square, manufactured in Japan to Japanese standards of fit and finish. I’m sure the square was generally accurate, however the product had the look, weight and feel of a cheaply made Chinese product, stamped with a rounded edge on one side and a sharp, burred edge on the other. You don’t get Japanese quality for $20. I should have known that. My fault. I gave it four stars because it costs only twenty bucks, then returned it. There is nothing special about this square; the manufacturing quality resembles what you get at the big box store.

Easy to handle. vary accurate . Well made!

The description states that it's aluminum but it's actually stainless steel, very well made and nicely finished, just the thing for fine finish and cabinet work. It might be too small for timber framing or work at that scale.

I bought this a while ago and noticed that my 90-degree angles were sometimes off, so I stopped using it. I found it recently while reorganizing my tools and decided to test it against some known straight edges and a high-quality combination square that I know for sure is square and straight. The 90-degree edge of this square is not straight. There is a high spot in the middle of that edge, so lines that I draw with it end up slightly curved. As a result, when marking on a narrow board, the scribe line might end at the high spot on the edge, making the line out of square. When marking wider boards, the line ends up square on both ends but curved in the middle. The 45-degree edge has the opposite problem -- it has a slight hollow in it. The edge with the fence is the only edge that is perfectly straight. I supposed I could try to fix these problems with a file, but they shouldn't happen in the first place. If you buy one of these, I would recommend testing it for squareness and straightness. But honestly I would not recommend this at all -- a 6-inch combination square can do anything this can do, is a similar size, and you can buy one from a brand that has better quality control.
