Don't take this the wrong way.
- Consider what you paid for it.
- Consider the intended uses.
I'd dare say, for most people, a $10 knife will do 90% of what they need for it to do.
Knives are like a lot of things (sunglasses, vehicles, carpet, steaks), in that, you can be perfectly happy with a low-cost version. The problem comes up when you get to experience the higher quality versions, and you never want to go back
It's like driving a Kia. You'll probably still get where you're going, but you'll get some funny looks, and you aren't getting there in style, if you know what I mean.
As long as you are happy with it, and aren't planning on going after any MutantNinjaRoboticGrizzlyBears, enjoy it.
