Myself says: “From the ‘Why didn’t I think of that?’ files: Two socket drive sizes on one ratchet handle! It really needs no further explanation. I’ve seen these wtih all sorts of brands on the handle, and most of them have been well made with a 72-tooth mechanism, minimal reverse torque, and positive action from the direction switch. One I played with in the store needed obnoxiously high reverse torque to freewheel, so this might be one you want to shop for in person rather than online. On many models the head comes apart with Torx screws, too, so you don’t even need snap-ring pliers to clean and lube the mechanism. (If you get the Astro Pneumatic Version, don’t get attached to the yellow grip — it won’t be yellow for long!)”
The version pictured above is made by Titan and available at Northern Tool, though as Myself said, there are lots of brands available. Prices vary wildly, with the Titan clocking in at around $10 and the disassembleable versions discussed above running $100 or more.
