A Siebe Gorman Non Magnetic steel diving knife with ingenious braised modifications to either end.
Brass sheath with canvas frog and stamped to both sides 'NON MAGNETIC A.P. 6261'. The end of the sheath has an eye braised on to hold the rope attached to the knife handle end. The great condition steel blade is serrated on one edge and marked to both sides with 'AP 6260 NON-MAGNETIC', brass collar and bakelite handle with brass end adapted for the rope to attach to the sheath end. A nice piece.
