Review: Mr. Pen brand tools are always great and this carpenter square is surprisingly hefty - This carpenter square is for crafting projects and paper arts and I wanted something made of metal but with a nice finish so nothing could get messed up or torn during use. Many "tool-like" measuring tools are made for wood or metal and no real thought to the finish being smooth and safe for work with more delicate surfaces but this one is great. Smooth, yet hefty, accurate measurements and an excellent square will make this a go-tool tool in my papercrafting and stamping arsenal. Works well and doesn't shift around during use. Quite happy with all my Mr. Pen purchases.
Review: Solid, accurate and easy to work with - This carpenter square is durable and very accurate. It’s a bit heavy, but that actually makes it easier to work with since it stays steady in place. The markings are clear and the overall quality feels reliable. Great functionality, strong durability, and good value for money.

## Questions & Answers

**Q: How much does this weigh in ounces?**
A: The seller states its weight is 8.15 ounces.

A: according to the ruler etched on the square the narrow part is 1" wide and the wider part is 1-1/2" wide.

**Q: how deep is it? The bottom bar is less deep than the top bar; how deep is the top bar? across the bar not end to end**
A: how deep is it? Not very deep
The bottom bar is less deep than the top bar? It is the same bottom and top
 how deep is the top bar? You can run your figure across the the engraved and feel that it is raised up

**Q: Are the markings along the ruler printed or engraved?**
A: They are printed/painted on, the people who are saying "engraved" are probably feeling the thickness of the paint. The paint job is quite poor on mine, I see the same defects on the seller's photos, just fewer of them.
