I found an older MATCO contour grip 1/4"er for $1 at a pawn shop and it's the smallest overall profile 1/4" rat I have.
Your post about about that Matco version is what prompted me to try one in the first place.
I figured I could get a deal on Ebay, but I discovered people seemed to want as much or more for a used Matco rebrand than I could get a brand new Wright for so that's what I went with.
The Thorsen 77M is smaller but it feels a bit dainty compared to the Wright contour grip, the Wright feels better in hand and will most likely fit into the same places.
I find it amusing that the ratchets head is the same diameter as 9/16 and 14mm sockets.
I wonder if the flex head will have this same grip size or larger grip size of their 1/4 flex handle which is a bit beefier and dare I say feels just a tiny bit better.
