I find a knife I own in 1085(bark river bowie)holding an edge and performing better than all other knives I own in same and other steels.Toughness and ease of sharpening make it my favorite steel, and it gets hair splitting very easily and cuts forever! Could it be a heat treatment that is a big factor in its performance because i have knives in 1095,154cm,vg10,1075,that do not perform nearly as well as 1085 regarding edge holding and toughness!
