 My favorite measuring device, Ola Woodworkers, Paul Carlson here, a small workshop guy. I'm a junkie for measuring devices. I've got my expensive Incras, I got the 6 inch here, I got the 3 inch here, I've got the combination squares, I got the calipers, of course I use those all the time. I've got larger combination squares, I've got all sorts of things. My favorite is this really little, very thin 3 inch by 4 inch little L square. This one is made by Zona, model number 37-434. Put that into Amazon and it'll come up. First thing I load up into my shirt before I start my work day, I don't have a work day, this is a fun day for me. Why? Well, number one, because it's an L square, I can hook it over the edge of a workpiece and have confidence that I've got it lined up. I'm not trying to feel and see if I got it on the very edge and then I'm off by a little bit. I can lap it over the edge and then I'm nice and secure. The other thing I like about it is if I got the right shirt on, it's easy to put away. If you've got a Samurai carpenter workvist who has all those pockets and certainly he's got a prized place for his, he's the one where I saw it the first time. I worked pretty hard to find one. I really did, it took me a long time, maybe I just did my search poorly. Anyway, this is my puppy, I love it. The others are certainly useful in given situations. Obviously the combination square, all the time. So I recommend this. I hope you find it helpful. Small workshop guy signing off.
