I have a much older and much less nice-looking version of the square pictured above hanging around my shop. I use it primarily for metal work, but as I’m sure most Toolmongers will attest, once you start using a tool for one purpose, you’ll pretty much reach for it whenever you need to do anything similar. So mine gets a little woodworking use as well. The one pictured above showed up in an Irwin press release we received last week, and though I’m not sure it’s really updated or new, I still wanted to mention it because at around $8 it’s just a great thing to have around.
The Irwin model lists a couple of basic features, including a cast zinc body, black-accented markings on the stainless-steel blade, and a nice little bubble-level. But honestly, I’d say you could pretty much pick up any model that looks and feels sturdy and solid. Let’s put it this way: I don’t know where mine came from. I found it in my dad’s stuff, and I still use it. I can’t really picture buying a replacement, unless I happened to find a need for two.
