Catalog Description (from when I bought it in the early 1980’s) :
Model 76 THROWING DIRK was designed by Harry McEvoy in honor of America’s Bicentennial. Like all Tru-Bal knives it is handmade of super-tough, specially tempered spring steel for a lifetime of rugged use. Thrown equally well by handle OR blade, it comes with heavy, handcrafted leather sheath and complete instructions for throwing. This is a true professional throwing knife — a real collector’s item you will be proud to own and throw! It is 13 1/2″ overall in length, 2″ wide, 3/16″ thick and it weighs 15 ounes — same weight as the Bowie-Axe throwing knife.
