That is not the Snap-on tool for Ford/Holley 94 jets, which has been out of production for a long time.
First, you can do the job with a normal screwdriver...best is a fairly large blade for tight fit in the jet slot with sides of blade ground down a tad to go through the access hole. Many smaller screwdrivers will also do the job, but with some slop in fit to the slot. Usually not a problem. Carb must have it top off, as a screwdriver can't carry the jet in and out.
The original tool is a socket whose business end is shaped like the current Holley tool (also replicated by Speedway), just better made...it is a long socket to reach from the access hole to the jet.
Actual driver is two nubbins on the shell of the socket, inner part of socket is a bullet nose that goes into the large opening in front of jet and grips it well enough (usually) that jet can be inserted and removed as well as rotated.
The current tools I mentioned do and look the same at the tip of a screwdriver, but are not as well shaped to slide into and grip an unseen jet.
Only way to get one is dumb luck at the fleamarket.
The tool shown above is just a screwdriver with a collar so top screws on a carb can be removed faster without slipping out of the slot...I doubt that it will even go through the access hole in a 94.
