I bought one of these a while back from Amazon to learn how to hone with, and couldn't even do that. Now it sits on my desk at work to open mail with.
I think the best way to describe them would be "thick, oversized, heavy folding knives", certainly not something you would want on your face.
I noticed on Ebay that expedited shipping is an option, my only question is, "why"?
Just my humble opinion, but I have a feeling the mileage won't vary much.
