It
does have the teeth: "The rotating base does have an interlocking V-grooved swivel base. It can be locked in any position 360 degrees. The 2 mounting screws work as expected. It has 3 mounting holes and was easy to mount to the bench."

That IS nice. Just like a Wilton. Certainly the best vise of that style.
But wait! So this doesn't get too confusing, for my post:
swivel = horizontal (helicopter)
spin = vertical (airplane's propeller)
My main beef with this style of vise is the large main handle you tighten/loosen the jaws with ALSO tightens/loosens the vertical or spinning axis. Any locking pin (or sometimes a screw) only serves to hold the rotation angle; the workpiece is not clamped at all. Contrast this with the horizontal swivel lockdowns; they are separate from the work holding function (as they are on any normal vise), so one can clamp the work once and horizontally swivel the vise as needed without doing the unclamping/reclamping dance.
So what? Well, I grind bronze sculptures after they cool down. LOTS of grinding. In a fixed, non-swivel regular vise, like a basic Wilton or a woodworking vise, a lot of time is wasted repositioning the piece in the vise to allow access for the grinder. With a common old horizontal SWIVEL vise, sometimes I can just unlock and swivel it a bit and grind, sometimes not even locking the swivel down (if the vise has enough mass). FAST.
It sure would be sweet to also spin the jaws (and workpiece) vertically too!
But with this Yost vise, and all vises that are based on this design, as soon as one loosens the main jaw to vertically spin it, the workpiece either falls out or needs to be held while one spins the jaw. Very awkward, especially if the workpiece is heavy. And my workpieces rarely are nice square and co-planar things, and need to be carefully repositioned in the jaws EACH time you unclamp to vertically spin the vise. Otherwise the sculpture slips and is damaged or worse, it hits the floor (or your foot!).
I called Yost on this, and they confirmed their two double swivel/spin vises work this way (as do all vises that look like them). I also emailed Bison and theirs too operates in a similar manner.
The only ones that allow CLAMPED vertical spinning are the Swindon, the Parker-type vises shown earlier in this thread and some old woodworking Wiltons (have one) and Emmert-type pattern makers vises, and the last two don't swivel horizontally as they were made to be mounted under a bench.
However, I have mounted my Wilton on a German "vise-lift" by flipping it over. Now it rotates in two axis and also goes up and down. The Emmert is WAY too big and has too many levers and other dohickeys to modify in this way.
That Swindon is one frickin' sweet vise. Parker too!
