I see the 105 is loosing ground in the poll. I'll take one last crack at it... Back in 2004, Buck did a signature series with the 100 series fixed blades where they redesigned the 105 (and 119) as full tang models with checkered walnut slabs. They were limited to 1000 each and were renamed 805 and 819. They are actually lighter in weight than their phenolic and aluminum pommel counterparts. Here's a screen capture of the catalog listing for them. Sorry it's a little blurry.

I hope Dogpound77 doesn't mind that I borrowed his photo of this extra special 105/805:
