    Are you really sure you want vise jaws that are brittle, very difficult to machine and leave marks in anything clamped?

    I replaced the jaws on my vise with ordinary steel into which I had milled a variety of V-grooves, both horizontal and vertical. Putting vertical holes to accommodate pins allows clamping odd shapes as is done with jewelers' clamps.

    A similar prismatic jaw for the Panavise removes the need to mount and dismount jaws for different jobs...

    I agree. Serious vises have serrated jaws yes, 2 or 3 times thickness of a typical file. Unless the jaw 'beds' are dang near perfectly flat, and perfectly seated flat-head screws [not actually possible, cone section are rarely concentric with body of screw], brittleness of a file will be on verge of breaking. Not braking, lol. Thicker material and socket heads front or back are common in good vises. I'd guess hardened jaws don't need a Rc above 45 something. A lot of them are coarsely face milled with flat serrations, and satisfactory in my book.

    For some things, yes. Not for everything, of course. I have soft plastic jaws with magnets to hold them on like the prismatic jaws in your link. I have bent aluminum sheet jaws, and wood jaws. Hard jaws can be good for hard and very hard materials. Which I sometimes have had to deal with. And I have material here for various other kinds and types of jaws. I also have multiple vises, in sizes from 1" to 6", and also made of several materials. Variety requires and includes versatility.

    Best thing about this entire discussion, and typical throughout our site;
    a] truths are evident,
    b] each of us have different parameters,
    c] a few mere sentences usually dilute the features we try to expound.

    YMMV
