PROVISIONAL SPECIFICATION.
An Improved Sheath, Sailors', or Butchers' Knife.
CHARLES IBBOTSON Cutlery Manufacturer 58 Cambridge Street Sheffield do
hereby declare the nature of this invention to be as follows:-
To fix a marline-spike, saw, pen blade or other article, in the handle of a sheath
or butcher's knife, to open and shut with a spring; I first get a sheet of steel and
fly or punch out the blade and tang all in one piece the shape required, the tang
being so cut out on the front edge and head end as to form a spring at the back,
leaving room for the spike to work and shut down like the blade in a pocket knife
& leaving the tang in center broad enough to hold two revits I then take rosewood
or other scales, shape of handle, drill three holes in them for screws or revits, fix
scales onto the tang and put two revits through both scales and tang and one revit
through both scales and marline spike tang this holds marline spike tight in
position against the spring, and allows same to open and shut like the blade in a
pocket knife, the wood scales being grooved down inside edge to allow spike to
lay flush with the handle when shut.
What I claim as new is the shaping of the tang so as to form a spring solid with
the blade, and the fixing and working of the marline-spike or other article, which
enables me to make a cheap sailor or sheath knife with a marline-spike or other
article inserted at the head end of handle.
