This Gerber Paraframe mini knife is great because it's only $8. This makes it a great candidate for your everyday carry, along with the fact that it only weighs 1.4 ounces.
It's got a smooth, 2" locking blade that's made iwth high carbon stainless steel. It's got a sleek look, and did I mention it's only 8 clams? Just go get one already!
