This
tutorial will teach you how to fit the guards on your
custom knife.

Once the heat treatment of your knife is complete, your
first step in finishing it should be to sand the flats
up to 1200 grit on your disc sander (at 1000 r.p.m.
max) in preparation for the final blade finish.
NOTE: The ricasso is now
ready to make the guard. The tapered tang should be
lightly ground on a 50 grit disc to ensure it is warpage
free and that the run-out is in line with the back of
the guard.

On the rear side of the guard mark out the centre line
and width and depth of the slot to be machined. Bandsaw
out the slot as shown, ensuring you remain within the
scribed lines.

Set up the guard in your mill with the cutter centred
on the scribed centre line, and the table to stop at
the end of the cut. Use an end mill ± 0.5mm smaller
than the required width, run at ±1800 r.p.m.
and set to cut .75mm deep with each pass.
When complete, start from
the top again and adjust to cut equal amounts from both
sides of the slot (for the required width) to fit the
ricasso. Stop cutting the moment your cutter reaches
the bottom (i.e. the front face), as the cutter diameter
wears at the tip it actually aids in creating a tight
fit on the front face, hence you work from the rear.

Clean up the front face on a 220 grit disc, fit and
correctly position the guard for drilling the rivet
hole, obviously already drilled in the tang prior to
hardening.

If you don't have a mill don't despair - two 10mm square
lathe cutting tools, a few hand files and a tube of
super glue can do an equally, if not better, job.
On your disc grinder,
round one of the edges on each lathe tool to serve as
the leading edge of your file guide. Glue the first
tool to the guard on the scribed line with the leading
edge facing you.
