My research has said otherwise, cheapest I have found in Canada is around $70 and I found out that the Native doesn't have liners. Imagine that! the Spyderco has a "glass reinforced nylon" handle with no liners and the knock off has full length stainless liners and G10 scales. It has to be said that the Spyderco is made in the USA, for those of you that find that important, and it is made from S30V, whereas the 628 is 440c (they claim), I finally took mine to the stones last night and I have no complaints about the steel.
The Spyderco Native is about my least favorite Knife.I find it hard to sharpen ,as the sv30 powder steel sharpens into shards and not smooth like carbon steels.Here is a place in Canada that has one for 60 dollars http://www.warriorsandwonders.com/Spyderco/Spyderco_Native_III_Plain_Edge_Folding_Knife .. Some of my Favorite Spyderco's are the Sanremnu made Byrd series..I have a Catbird in my pocket right now..I have some expensive knives but I'm not a steel snob..If it has functionality, I'll carry it.
