When I moved into my current house, the prev owners left this cheap ass micro serrated fillet knife in the drawer. I almost threw it out when I found it. Well, it has become one of my fav knives of all time! Super pointy flexible blade unzips envelopes, boxes, zip ties, and those bomb proof heavy clear plastic casings that everything you buy these days is packaged in. You could have you finger lacerated off trying to open one of those heavy clear plastic things, but that knife, with the micro serrated edge unzips it like it wasn't even there. 5 years later it hasn't dulled one bit. I friggin love that knife! I bet you could saw concrete with that thing!
