Can anyone explain how the Columbia River Knife and Tool K.I.S.S. (CR-5550) works? (http://premiumknives.com/ShopSite/Folding_Knives_Menu.html)<br><br> I can't quite figure it out from the picture. The "24 Karat" version has a bigger picture, but there appear to be three knives in it - one of them is the knife opened up, and I assume one of them is the same knife closed and turned over; but what is the third one? It's a different shape; is it a different version of the same knife? there's no explanation. <br>It appears that the knife, when closed, has the unshielded blade lying alongside the handle, instead of being enclosed inside. Is that right? If so, how safe can that be?<br>And what was the brilliant idea that the designer had when he designed the "Delilah's P.E.C.K." (model 5520)? It looks identical to the 5550, which is quite a bit more expensive. <br>It may be a neat site, but their marketing sux. :-(
