Here is my own flint knife that I made about 12 years ago along with the brain-tanned deerskin sheath for it. The blade is black Arkansas Novaculite, a type of chert, with a white translucent streak runnin` through it and is a shade over 3 inches long. The blade is hafted in the antler of a buck I shot and wrapped with the back sinew from the same deer. This knife has skinned and boned out several deer and has been resharpened once. I plan on havin` the shape of it and my flintlock rifle cut in my tombstone.
