Description

Add grip to your measuring tools with JessEm's Precision Squares featuring patented Flex Grip technology. These squares are crafted from 301 Full Hard Stainless Steel for durability. Each marking is etched and then engraved using a laser system to withstand daily wear and tear, ensuring they never fade.

JessEm's rigorous quality control guarantees one of the most accurate measuring products on the market.

A new feature never before seen on a Square is JessEm's patented Flex Tabs which grip virtually any surface softer than steel. This means no more slipping when marking or scribing your workpiece, metal, paper, etc.

Scribing notches, spaced every 1mm, ensure perfectly accurate lines across your project. Each square features a balancing tab that easily engages, locks into place, and allows you to balance and scribe across your workpiece with ease. Unlock it when not needed.

These squares are perfect for woodworking, drafting, metalworking, art, design, and more. With a range of sizes, you'll always have the perfect ruler for every project.

Well built and a good price.

Well built and a good price. Cheaper than Woodpeckers. I have a few JessEms pieces, butI've most of Woodpeckers. JessEms needs to expand the range.

Nicely made. If you need 150mm get the 200mm version.

Nicely made and the protective board mount is both practical and a nice touch.
This is my honest review and opinion. First time buying a JessEm product.
Advertising as 150mm is misleading it's really 120mm and the line scribe ends at 100mm.
Accuracy. It's accurate enough but have to question these high end squares. For example when attempting to compare with the Benchdogs 300mm square the blades do not align (as you might expect). Clear daylight can be seen. In my case it appears that the underside tip of the blade (in both cases) touch each other and perhaps in doing so create the gap.
In woodworking terms they are accurate but disappointing at the same time.
Maybe I expect too much but still surprised given the size and price.

square SQUARE !

Very happy with my new JessEm 150mm square ordered from Woodworkers Workshop who sent my order very fast to me and was packaged very well as usual. The square was the quality that comes from JessEm products and was spot on square and very easy to read the markings. I have since ordered and recieved the 300mm square and the set of fantastic non slip rules.
Broke now but very happy ! Thanks JessEm & Woodworkers Workshop.

Nice square

It feels great in the hand and is dead square. The matt finish to both the blade and the stock makes it easy to see a sliver of light. I have the 150 and 300 mm which are a great pair.
