I use a 3.75" drop point of pattern welded 15N20 and 1084 steels, flat ground and differentially heat treated, It's got brass guard and pommel with burl Ironwood handle. No thong hole. I use a Lansky to sharpen it as needed.

Heat treat quality is more of an issue to edge holding than alloy is. Though some alloys are a real pain in the arse to sharpen.
