It should be worth noting here that Ernie did not grind the blades on the '98 Commanders. They were factory made knives. It is accepted wisdom that he may have ground SOME of the blades, most likely a few of the true satin ones. The original knife design for these was the ES1-M, which was designed as a SERE knife for some units at Ft. Bragg. After a few modifications, the Coronado Teams ordered a total of 200 of these, which featured 4" chisel ground recurve blades, all customs carrying the SpecWar logo. This was in 1995-6. In 1998, the Commander made its debut, a ~80% sized version of that knife with a double ground recurve, and was promptly named Blade Show Knife of the Year. Later, a 4" bladed version of the Commander, called a Super Commander, made its appearance. These had the EKI logo on them. A few have been made bearing the SpecWar logo, which indicates they are custom made knives. If a EKI logo'd knife, its worth about the same as a current one; if SpecWar logo'd, its a solid $1-1,200 knife assuming excellent condition.
