My first and second both have the sharpened back.
For chopping, I seem to remember.
The upper blade grind is to allow rough cutting or hacking, saving the finer main edge below.
The wooden handle version has been sold as the Auto Messer (car knife) and was included in some survival kits sold by Puma.
I have a White Hunter, but can't say I use it much. The Puma models I like better are the Outdoor, the Model 3589, and the little Hunter's Pal. And they make good lockblade folders, too.
Puma advertise that their knives are as sharp as a razor and as strong as an axe. I was astonished by Iggy's post about one
"shattering" as he dressed an elk with it. I'd like full details on that and think that if the knife was a genuine White Hunter, and was not being really abused, that Puma will replace it.
Was the knife being pounded through the pelvis, or what? People abuse knives that way, for duties properly assigned to an axe or saw.
I have seen a couple of Buck blades with half nickel- like gaps where the blade broke out when hammering the blade against bone. That's a major no-no, and I think would break other brands, too.
I've had no problems with either Puma or with Buck, but I don't treat knives badly.
I've never heard of ANY knife "shattering." Maybe we don't understand that word in the same way. ??
If a Puma knife failed, that batch of blades probably got faulty heat treatment and Puma will make good on it. They 're a reputable firm, with roots back to 1769!
