I have a cool little simple combination square that sees lots of use around the shop in terms of everything from basic metal fabrication to hanging pictures. I inherited mine, but you can buy one pretty much just like it from dozens of manufacturers. Hell, I saw an Irwin model that was identical except for its blue finish. Then I came across the one pictured above.
My first thought is that it’s the result of too many committee meetings or focus groups. Can you even identify all the tasks for which this thing’s designed?
The documentation I saw claims “10 uses” including 90-degree inside and outside squares, 135-degree and 45-degree inside squares, horizontal and vertical levels, a T-square marking gauge, and a depth gauge. Granted, most of that is standard T-square functionality, but I’m really not sure about all the doodads on the left side.
Seriously, though, is this something you appreciate? Or more generally, do you like tools which combine many functions into one tool, or would you rather have multiple simple tools for each job?
