I have been watching a lot of Richard Raffan and he often uses what he refers to as shark jaws which are very versatile. I have searched most of the chuck manufacturers and can't find that type jaw. All of my chucks and jaws are Nova.I have searched their website and also Record Power as I understand will they fit Nova Chucks also. Any suggestions from the forum.

This is a link to the vicmarc shark jaws. They are tall serrated jaws with a dovetail at the top.
You might find similar jaws with other manufacturers called tower jaws. ONEWAY has a series of these


 
These are the Teknatool Nova internally "serrated" jaws I use the most. Grip squares and rounds, mostly for various spindle turnings.
They have dovetails on the outside, unlike the Nova Greenwood jaw set.

I have very similar ones to numbers two and three in your picture, very useful. They are supplied by a company over here called Charnwood and fit Record Power and Nova Chucks.

Edit: I’ve just looked at a RR YouTube video and he calls these Shark Jaws and they’re mounted on a Vicmarc 100 Chuck.

I’ve seen these called Ripple Jaws by other companies.

The Shark Jaws are manufactured by Vicmarc.
 
I don't understand the need for the profile on the outside. Do some make really deep recesses in big pieces where this would be useful? I rarely use more than a shallow recess, some are as shallow as 1/8" even for bowls and large platters.

I use someone similar Nova jaws but they are "grippy" in the inside for tenons but the outside has only a dovetail lip at the end.

Yes, I was wondering that as well John. I also have similar jaws.

John, are these jaws like what you have? I just bought a set on Amazon and looking forward to seeing how the hold my longer workpieces.

I do have those long-nosed jaws for the Nova and like them a lot. But the others I referred to are different. I'm rushing to get out the door and can't check now. Last minute tasks prepping for a demo this evening.
