I put a two foot pipe over the adjuster-arm on 10" visegrips yesterday, to spin a stuck tie rod end yesterday. Squeezed them shut with all my might to get a bite and then leaned on the pipe. No damage to the pliers and we won the fight.
Visegrips make pretty good hammers too.
Vise grips are a great starting point for custom tooling. I've added a nut to the adjuster for repetitive tasks. It's a handy addition, but there isn't much clearance at the small-opening end of the range.
Those look like a shop-made example of these...
It's interesting that the scoop panel runs right up to the reinforced jaw (the same as the ones above). I see that the adjustable wrench you posted when starting the thread also has a screwdriver on the end of the handle.
One of the links you shared in that thread has a wrench like this one...
I've got a nice 3/4" wrench you can have, if it's worth the price of shipping.
(I'll be going to the post office to return some shoes).
The chrome is a little worn, but intact.
I recently found a partial set of SK WAYNE 12 point combination wrenches.
I had the two smallest ones already...
I stand corrected. I assumed someone lopped off a knurled handle to make a stubby.
I have yet to come across a Firestone tool, but it's not due to a lack of shopping!
That looks similar to my OTC. All the ones I have seen have four rivet holes for the emblem, but iirc, yours has two. The bottom corners are square on my OTC box. I really like the rounded ones on yours, but also appreciate the double-rounded OTC top. So many cool boxes to choose from!
