I carry an Eickhorn Recon Force combat knife on my night and day hunts. It is excellent for both two and four legged animals. It comes with an US M8A1 combat sheath. Eickhorn makes knives for the German Bundeswehr (Army). The standard Army knife is a tanto style. I like the dagger style, because I can make a clean stab to the brain if an animal I shot is still breathing.

Time and time again this unique OES blade has demonstrated distinct advantages over all other non-OES products, which shatter easily under normal stress loads and fail to meet the extreme field operations of todays soldier.
