If it was anything under 6 inches, it would be a no brainer 420HC with me. Anything over that, I would ask myself, is toughness or stainless more important with this knife I want...
420HC is quite tough. If you are looking for a cheap chopper, either get a Scrade SCHF55, SCHF35, or SCHF37. That is 3, 5, and 7 inch blade lengths, all at great prices. I beat the crap out of mine and it takes it like a champ.
OR an Ontario field knife or 12 inch machete.
There are lots of choices.
