Cutting a penny in half isn't special; but it's a cool demonstration because people never think to cut a penny in half. That you are bragging about that quality indicates that they suckered you into believing their spiel. Before finishing this post, just to make sure I wasn't wrong, I walked across my classroom, grabbed a pair of School Smart brand scissors ($1.99) and cut a penny in half. edit: ironically, it just occurred to me that I could rebrand the cheap scissors, and go door to door selling them based on a demonstration of cutting them in half. "Look! They cut a penny in half just like a $100 pair of Cutco scissors!" I'll leave out "just like a cheap $1.99 pair of scissors would, that I just rebranded and am now selling for 5 times that amount (or 50 times that amount if they were Cutco.)" Hey, isn't this where you're supposed to claim, "surgical stainless steel" (a phrase which has no real world meaning)?
"Like 3 tiny razor blades" - comparing them to razor blades - implying they are sharper than they really are (after a bit of use.) You can rename "serrated" if you want, but that's what they are. That blade design is so that you don't realize that the knives are dull - after a while you're sawing through food, rather than cutting through food. Big deal that you get free sharpenings. I used to live 15 blocks from the main headquarters. THAT was too inconvenient to get my knives sharpened. I use knives just about every day - I'm not packing them up and shipping them off to get them sharpened and shipped back to me... especially when I can grab a steel & get an incredibly sharp blade on my non-serrated knives in about 5 seconds prior to use.
edit edit: I love their fisherman's friend knife though; nice filet knife. (With a non-serrated edge.) The blade isn't any better than the other 5 or 6 filet knives I own; I just like the handle more. The ability to change length is kind of gimmicky; can't recall that I've ever used that (and I filet hundreds of fish each year.) And, the Kabar knives are very nice.
