Just received the two Boker daggers I ordered: Schanz Integral (top) and Applegate-Fairbairn Desert Storm (bottom). Both knifes appear well-made and use 440C stainless steel. The A-F was made in Germany, has fiberglass reinforced handles and seems to be the better handling of the two. The Schanz is a massive piece of steel with canvas micarta handles, and gives the impression of extreme ruggedness. It was made in Taiwan.
I like both knives. My only complains concern their sheaths. The A-F has a kydex sheath with a very complex mounting system, but no instructions. Had to go online to find out how to open and mount it. The Schanz has an all-leather sheath. Its okay, but not up to the quality of the knife.
