Review on 🔨 Mastering Carpentry with Mr. Combination: Carpenter's Ultimate Woodworking Tool by Richard Dean

I bought the ruler because I was looking for a 12" metal T-square for drawing with graphite pencil and didn't want to pay $$ for the privilege. I don't really have any complaints about the ruler, but I will say that the adjustable square is dangerous - you really have to pay attention to where the ruler is in the slot because if it's not exactly where it's supposed to be, then the pen will not fully back it up. Other than that, it's a great bang for your buck.
