3 5/16 inches closed. Good fit and finish all around. Very pretty celluloid is stable, at least so far for the last 80 years or so! Joints probably a little dry; otherwise snappy. Desirable tang-stamp and match strike punch. Master clip blade has great grinds but is a little short. This knife has been cleaned. It is a nice knife at what I believe to be an attractive price. Substantially less than what I paid. $60 shipped.
