Shhh! Calling a cheap knife good is a heresy. But with modern metallurgy and production methods it's easy to make a cheap, serviceable knife. Even stainless is so much better - what they use in production facilities where you work with a knife 8 hours a day. And those guys would buy knives more expensive than Victronics/Forchners if it made life better.
Just keep it sharp and you'll make it through any game animal. Dad once field dressed a deer with his cheap pipe knife and it was far from razor sharp.
