Years ago, I bought the flare nut crowsfoot wrenches off Ebay, from a seller saying their father in law passed and they were helping their mother in law sell the tools. Don't remember the price, but decent. Never bought the open end crowsfoot, which I think I have some of in the shop toolbox.
My old shop, the owner was the one that told me this is where he either took older sets of wrenches that lost some, found one off's at garage sales, etc. and cut them shorter, because in most cases he could hold one side and turn the other with a ratchet or something. (and I found that has mostly worked for me as well)
12 point ones are/have been great for sensors (and I mentioned in another post, finding Snap on 12 point ones for $1 each on Ebay years ago, all marked, and bought them all for the shop, for O2 sensors.
Since we are discussing these and sizes, what do you specifically find the 15/16" useful for? Would a 12 point flare nut work as well, worse, better then the open end? (I've had so many open end wrenches slip, here in the rust belt, I am just leary with crowsfoot ones where I don't feel it through the handle)
Thanks
