Review: Love this combination square! - Love that is stainless steel so it won’t corrode in humid Florida, love that the numbers are etched and won’t rub off, love how it’s a very solid hunk off metal and not some plastic Tonka Toy piece of junk, love how it has both inches and metric, and love how my table saw blade is finally square!! And all at a reasonable price. This is the one to have! Review: Really a great value. - I am not a tool snob, but I do like quality tools. I already have a really nice PEC square that is built/rated to very high specifications. I thought I would buy this just to have around when I needed something for measuring lumber (2 X 4 ) without breaking out my really nice square. When I opened the package I was really impressed with the weight of this tool. It does not feel like a cheaply made tool at all. Then I did the test where you take the square - draw a line about the length of the square, then turn it around and duplicate the line. To my surprise this square is every bit as square as my PEC! If you are new to woodworking, I would suggest picking this square up. I am going to treat this tool as if it cost me 100 bucks just because it is so well made. I wish all low cost tools were of this caliber of quality. ## Features - COMBO SQUARE: This Johnson combination square was designed with maximum accuracy in mind - its square head is CNC machined for greater accuracy. - STAINLESS BLADE: This combination square has a stainless steel blade with etched graduations in 1/8", 1/16", and 1/32"; as well as millimeter graduations that are permanently imprinted so they will never fade or degrade - ACCURATE MEASUREMENTS: Auto-Lock blade assembly ensures precise alignment for optimal tool performance - APPLICATIONS: Ideal machinist's square; straightedge; adjustable try square; miter square; marking gauge; and depth gauge - PRODUCT SPECIFICATIONS: Accurately measure 45° and 90°, mark miter cuts and find depth as well as simple distance measurements.

They were sharp and damaged all over. Compared to those this one is golden. It still seems a little rough around the edges, but is much better quality, and the machining is smooth. There is still the occasional small gouging, but it is finished over and not sharp to the touch. The locking mechanism is very cheap though. It really drives down the quality of this tool. The ruler also has edging issues where it is finished to much casuing the lines to have been worn off. ## Frequently Bought Together - Johnson Level & Tool 400EM-S Heavy Duty Professional Inch/Metric Metal Combination Square, 12", Silver, 1 Square - Johnson Level & Tool 406EM Professional Inch/Metric Combination Square, 6", Silver, 1 Square - IRWIN Tools Combination Square, Metal-Body, 6-Inch (1794468), Blue --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.in/products/16045861-400em-s](https://www.desertcart.in/products/16045861-400em-s) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-05-09*
