Jim i have ordered a DVD of the Evolution of Tlingit daggers. My Jun 19th post has a link well worth looking over regarding the Athabaskan version of forged copper daggers. Ward the swirls are volutes they appear in older European weapons and may be a link to Migration to Alaska. The copper bolsters are separate and swedged on.
I put up some shots of the volute daggers. first from the top is all copper Athabaskan/ Dene in origins the third is all copper both of these are flat on one side but, not the rounded profile of the third and fourth daggers. Copper Tlingit daggers have a stepped central ridge due in part its thought to cold forming. I haven't figured out where these other dagger came from.
I found a forum thread that mentions, about the Slave killer never having actually killed, that being left up to a double bladed dagger called goox du een. if the slave wasn't released??

I included closeups of the blades textures in hopes some of our knowledgeable metal experts may see something of interest in them.
Oh, the eyes question Story goes they emulate rams horns.
