The Condor Nessmuk is patterned after the knife designed by the well known outdoors man George Washington Sears in the late 1800's. His book "Woodcraft and Camping" is excellent. The knife itself has a blade about 3 3/4" long, 1 1/2" wide, and .113" thick. The distinctive hump facilitates opening big game without puncturing the internal organs. Again the handle is about 4 1/2" long, and is sized for average hands. The leather sheath is well made, and holds the knife securely.
