This is the new clamp from Axminster, supposedly a superior design. It looks almost as if the remit was to put the adjuster/tensioner call it what you will where it has least effect. What possible gain can there be?

I suppose there are cases where it would be useful, I see it putting an awful lot of strain on the threads and back piece of the top jaw though. I wonder how long it would last?
 
designed to stop bits moving(just) long enough to ram in a nail or screw. Mind you with the amount of pressure you can apply from that design, glue clean up will be a thing of the past
 
Old design but pared back to be just functional.
Forgotten original (patented from Warwick) and can't get to the box with it in to see who.
The Carver style of this design are superior.

Can't seem to find a link but there's an oriental chap on utube whom I watch occasionally who uses them quite a bit.
Edit...found the dude,here he is making a fancy version of a shooting jig for an electric plane

Reminds me of the old 'Jet' clamps - beautifully made but they still failed to sell. Remember them ?!"

Yes still have a pair of Jet clamps they are really good to use for metalwork nowadays but would not be without them.

In the vid, you see him using the clamp and at 5:00 you see the board he has clamped move. But very interesting video - not seen this dchap before so may watch more
 
I can’t see a fundamental problem with the design. I find with my other bar clamps (Bessey admittedly) that it’s very easy to dent the work despite the large plastic clamp pieces. Depends what you are doing with it really. Plenty of welding clamps work this way

The load on the screw is quite high. With a jaw depth of 95mm there must be about 80mm between the pivot points, and the screw maybe 30mm below the bar pivot. 200kg clamping force loads one jaw at 100kg, so the load on the screw is 80/30 x 100 kg, presumably threaded in about 15mm of ali.

Welding clamps surely are just used to hold things in place, surely? You're not trying to squeeze steel tenons into steel mortices.
