I'm Norwegian too, and buy about half my knives from US online retailers. For something like what you're after, I'd probably buy it in Norway to save some hassle though. I'd do one of the following:
The XXL chain sells Master Hunters -- and their policy is to match anybody else's price. So you go to
www.skytesport.no and print out their knife page, which lists Master Hunters at 695 NOK and then you bring this printout to XXL and ask them to match the price. (If Skytesport has the knife in stock, by all means buy it from them. They're good guys and deserve your business, unlike XXL. But if they actually have it in stock, I'll be surprised.) Save 30%.
Alternative 2 is getting a Fällkniven; I'd second Redguy's "H1" suggestion. As far as I know, the best prices in the country are at Aker Lås og Nøkkel at Økernsenteret if you are a forum member at
www.sluttstykke.com. Aker has a sponsor tab on the forum, give them a call. The H1 (which in my opinion is a far superior knife to either the Master Hunter or Vanguard) costs just over 1000 NOK there, approx 140 USD.
Alternative 3 is just getting a Helle. I used to hate these things for no rational reason until I picked up a Fjording on sale -- and this cheap little laminated carbon steel blade gets sharper than anything else I own, including expensive custom blades. I called up their factory at one point and they apparently harden their edge steel to 64 Rockwell, which is pretty darned hard for a knife that costs you 2-3 hours @ minimum wage.
For allround hunting use I'd recommend something like a Eggen, Veidemann, Fjellmann. And if I remember right, they all cost less than 400 NOK at XXL. That's 60% less than a Master Hunter, and I might argue it gets you a better knife.
