I just bought a brand new Benchmade 154CM Mel Pardue, and it doesn't seem to be very sharp at all. This is my first quality knife, and I expected it to be more "razor sharp. Is this normal? I asked the guy at the store about how to shapen it (before I noticed it wasn't all that sharp to begin with) and he said to just send it Benchmade and they'd sharpen it. Should I do this, or would it just come back the same way?
