cheap OTF knife

Recently I ve bought this OTF (out the front) knife. It is a double action knife which means that it opens with the slide button and closes with the same button. The knife is made in Italy and has a metal handle. The seller told me it's from Herbertz, but I m not quite sure since the mark on the handle states concord. I decided to go for this knife since the mechanism shall be very solid at a reasonable price. Unfortunately, Microtech and H&K as well as Benchmade OTF knives are too expensive for me.
