One problem with buying from a store front retailer is that you sometimes get the "Demo knife" from a less than totally scrupulous sales person. This knife may have been picked up a hundered times and had rope, or paper or hair, or all the above, Thus the great factory edge is long gone, and the knife goes back in the box and a new one is pulled out for the "demo blade."
One advantage of buying over the internet is that you don't run into this problem.
My advise? Next time, check sharpness before you hand over the cash, if it doesn't make a nice neat bald spot, ask for another one.
As far as this one goes, maybe you can take it back to the retailer and ask for an exchange?
I LOVE the AFCK! Got one of the very first production models and would never part with it. It's my daily carry blade!
I cut it, and I cut it, and it's STILL too short!
