Query: Razor sharp

I've had this knife in my block for a while now, and I'm still impressed.For a cheap knife, the stamped blade performs very well. The edge is razor sharp from the factory, and stays that way with minimal effort. Treat this knife well and you will be very happy.That said, before you buy, give some thought to whether you want a straight or curved blade. Victorinox makes a similar knife with a straight blade, which may be preferable depending upon style.Don't be put off by the lack of flashy "Three Rivet" styling. This knife is all business.
