I have/had a Rigid G-10 folder, the exact same model you have. I bought mine a while ago (about 4 years) from an online dealer. I got it for about $30, and it was a great deal, even then. I sold it to a guy I work with, and it has become his EDC. He loves the thinness of the package, and has had no complaints in the last two years. The ATS-34 was done very nicely, and the G-10 handles seemed quite sturdy. If I came across another one for under $30, I'd snap it up in a minute, and if the guy at work ever tired of his, I'd buy it back for the price he gave me, with no qualms. Great materials for a great price. It is actually the only G-10 folder I've owned. Sheesh, I need to get out there more!
Mine had no problem with the lock-bar coming in contact with the blade. Sounds like something you need to take back and get a replacement for.
Enjoy your knife, as it is a pretty good deal, for the money. It should last you as long as most of the higher-priced companies out there.
