4. Cutting oil ( I use a mix of Marvel's Mystery Oil and WD-40)
5. Finishing Tools: Metal files,Sand Paper (Your choice)

Marlinspike Sennits,Whippings.etc, for the Handle..

Step 3: Mark,Cut Sheepsfoot Blade.
Sheepsfoot blade Cut.
Here is how Wikipedia describes the Sheepsfoot :
A sheepsfoot knife has a straight edge and a straight dull back that curves towards the edge at the end. It gives the most control, because the dull back edge is made to be held by fingers. Sheepsfoot look like a sheep's hoof. They were used mostly by sailors in old times, as the shape of the tip prevented accidental penetration of the work or a person when the ship rolled suddenly.
Also Back in The Age Of Sail many Captains and Mates would order the ships Carpenter
to break the points off of Knives to prevent mortal wounds when sailors fought.
1. I chose an angle that would minimize blade loss and Scribed.
2. Place in vise at comfortable angle for cut.
Note: I used rubber to pad the jaws on the vise originally.
and used a vise that was mounted, photos are for demonstration
3. I Make a small nick, Cut.
Step 4: Finishing the Blade
I use Metal files and various grits of Sandpaper to obtain a smooth
finish. Starting with a crosscut file, Then I went from 100 grit and
progressed to 220, finishing it out with 320 wet/dry with light oil.
I resharpen the blade to a good working edge.
Step 5: Final and Misc.
I made this Mod on a Voyage from Honolulu to Kirimati
in The South Pacific in 2007. 3 Ships and several thousand
Nautical miles later it has stood up to the abuse given to it,
keeping a good edge and lightly oiled was not a problem
and most of its original finish has remained intact. Here are a few
final photos showing the knife and sheath.

Voyage, Mysterious Shipwrecks on uninhabitable Atoll there:
