Johnson Level & Tool 406EM 6-Inch English/Metric Metal Combination Square

Nice quality tool, no problems here, great solid quality.
-A nice extra bonus was a little metal scriber with a threaded brass knob…
The tool I most often use in my woodshop is the Combination Square and it seems there are never enough at hand. As is sometimes the case it’s necessary to pad an order to get free shipping from Amazon so I threw in a few of these. This is a GREAT Combination Square. I own other hand tools sold by Johnson that were made in various countries. This one I believe is made in China and is of better quality than the versions bought years ago that were made in Taiwan. I also have some levels made by Johnson that are light, straight, and maintain their look even after years of use.
Once I got the “Big Johnson” tape measure from a local hardware store a few years ago, I was impressed. Since, I’ve purchased about 7 of their tools through Amazon and have been happy for the value and quality of the tools. Through, “buy both and save now” you can get great deals and I picked up this handy little square. It’s small enough that it fits in my tote, which was my concern and it even has a special coating on the ruler portion which makes it resilient to rust and corrosion. Great value for the 7.99 I paid.
Needed a square to replace a couple that were broken. Impressed by the solid metal construction.
This square is now made in the USA, and, like our automobiles, is just not world class. Sorry, I’d love to say the “Made in the USA” still meant that it is among the very best, but certainly not in this case. It is a tenth of the cost of the Starrett, which is still world class. My “square” came considerably out of square and the blade had been dipped in some sort of protective coating which had dripped down along the edge of the blade so it was uneven. After taking the coating off by 600 grit paper on plate glass I was able to square up the tool with some diamond needle files used in the slot of the body. The product comes with a “Satisfaction Guaranteed” label saying that the company will replace it….with what? Another with the same problems? Also the scribe is not sharp, not very hard steel and requires many turns to remove it from the tool, which is not very convenient.
