Oooo, Oooo, The "Scrap Yard K-Nine ( Like the canine / dog tooth (The Killer 9").
A Scrap Yard double edged fighter about 1.4" wide, .33 thick & flat groung on both edges down to the spear point on the 9" blade. SR77 with a Res-C handle of course. Perhaps with a molded guard like the Regulator has.
