Preciva Woodworking Rule, Combination Square, Steel Right Angle Ruler, Engineers Set Square, DIY Measuring Tool 45/90 Degree,Carpentry Tools with 12inch/300mm Woodworking Rule (Woodworking Rule)

First, let me say that I worked a long time as a tool & die maker, so I know a little about precision. That being said - out of the box, I wanted to know if the block would tighten on the rule and hold it solid because so many seem to have had problems there. It does. Next, I checked the accuracy of the etchings from the start of the rule. The etchings almost have to be accurate, but they can easily be offset from the front edge. They were dead on. Next check was the accuracy of the 90⁰ and 45⁰ angles. I found a tiny, tiny inaccuracy, so I went looking for it - found that the rule had about a 1/32" of side play in the slot, which could generate an error of a few minutes of the degree. As a tool maker, this could be devastating. But this isn't intended to use in a machine shop making parts for aircraft, it's for woodworking. I doubt if the fence on my table saw is this close. Honestly, if you think you can control a saw through wood this accurately, get over yourself. This tool is great for a diy hobbyist, or a cabinet maker. I recommend it without hesitation.

Das Produkt ist eine billige und schlechte Ware aus China. Das Lineal lässt sich überhaupt nich feststellen. Man kann dieses Werkzeug nur in den Müll werdfen. Das Rückporto nach England muss ich auch noch selbst bezahlen. Eine riesengroße Frechheit aus China und England

This little ruler square is perfect for my woodworking needs. hangs on my pegboard and is fully adjustable with a quick turn. I also find myself releasing the ruler from the square block quite often and not picking up my other metal ruler as I like the tick marks and edge on this one better. Excellent quality for value. Ordered one that slipped a little and their customer service quickly ok'ed the replacement. I will be buying more products from these folks.

This feels well made. I read reviews that said the wood part was too lose. If anything it is too sung and a bit hard to move.

The construction of this is surprisingly solid. The metal part is VERY sturdy (seriously, I was able to use it to unscrew a giant flathead screw when I couldn't find my giant flathead screwdriver) and wooden block is solid, ans the knob is too.The block slides easily when unlocked, and locks solidly when locked in place. The angles are true and won't change.All in all, this is perfect for drawing and woodworking. And giant flathead screws I guess.
