The #84"S" was used, from time-to-time but not the norm. I, also, would have to see the front. Sometimes a handle-wrapped keeper strap was requested. The finger grips had nothing to do with it. Johnson roughbacks were the standard sheath provider even when finger grips were still being offered on 3/16" knives. The elimination of providing finger grips on smaller stock took place well after Sullivans was the sole supplier of Randall's sheaths.
