Hi Victory,
I'm not a commercial diver, so I can't say how well these knives do in that profession. They are certainly different from what we generally use in sport/technical/military diving. Ours generally includes a line cutter and a "hammer head" end on the handle. Wouldn't this also be needed in commercial diving? I really don't know and would like to learn.
Thanks,

Hey George,
You ask a good question, you really have me on what a hammer head is - are you referring to the steel "butt" found on most diving knives? If so, no we (i am also an offshore diver) never really have the need, although the handle of these knives is both hard enough and i my thinking large enough to give most bothersome small marine animals a good whack.

infact i have used it to clear some nasty barnacles on the legs of a rig trying to access a clamp nut.not the best tool for that job tho mate- as my knuckles will attest to.
In regard to the wire cutter, this serrated blade is awesome, you really have to see one. It cuts almost anything and my guess is it would out do any standard knife mounted wire cutter for sure.
I had to clear an 80mter supply vessel's prop of 100m of industrial marine nylon rope in the UAE 3 years ago. That is the stuff about 6-8 inches thick.
Now you might think so what it was nylon!
the stuff was wrapped around the prop and shaft 50 - 60 times!It was a tough job and when i managed to cut the outer layers i found the inner layers had melted and fused together due to the shafts frictional heat on the rope.
The job took me 100-120 mins to complete so you can imagine the amount of cutting involved. The Victory (Green River) absolutely smashed it! By the end of it, i was bloody stuffed but the knife was not.
Admittedly i retired the knife to deck work after that(still have it) and pulled out a new one for in water stuff as the blade was a little dulled.
And please dont get me wrong here, there maybe some commercial divers that dont use the green river, but i have not worked with them. I still have many parts of the globe to work in, but i have worked through Australia, New Zealand, Asia, middle east, and Nigeria. I can tell you the guys there are using the Victory (Green River offshore name) divers knife.
I hope this is of some help, and i hope it does not come across as a sell document - its not, i actually presumed the name was known across all dive areas, but i actually know little about your area of expertise - and we divers should NEVER PRESUME
cheers mate , and thanks for the welcome in
