All About Pocket Knives
Price tag was $6.
Most of the Imperial/Tradesman knives are not very good, but a couple of are OK. The Apex was poor, as were the Frontier branded Imperials.
The best were the Imperial camp knives ($1.99 on closeout), and I was suprised by the lack of blade play in a white plastic-handled peanut ($1.39).
Edited to add: I'm pretty sure they're all stainless.
