In my opinion the Bifrost pattern damasteel is the best, so good looking and what a cool name (click the link in the name).
This is a smaller neck carry version of my original Bison Bushcraft Knife made in 4mm Bifrost damasteel. I've gone to town on this one with antler bolsters, Stabilised Box Elder Burl scales, Forest Green liners and Nickel Silver pins and thong tube. Even the scabbard is made from Pigskin lined Vintage Sedgewick leather with hand made antler beads for the leather neck cord.
With all that, as per usual this is a perfectly functional blade hardened to 61 hrc and carries a 27 degree scandi grind.
