Tapered
tangs can be terrifying to grind for most new makers,
it's only practice that makes perfect - well, almost
perfect. I can clearly remember to having to resort
to filing them on my first couple of attempts. The
fact
is they look and feel so good (weight wise) on most
contemporary designs that they cannot be ignored.
We start off with a surface
ground profiled blank, drilled for the necessary rivets
and thong tube, followed by a series of larger holes
along the centre line.
You have no doubt
marked out the cutting edge at this stage - so use the
same markings at the end of the tang.

The sketch shows a center line drawn along the handle
which angles down towards the end, as the handle drops
(common to most designs).
We start our grind on
this section of the tang first.

Using a 36 grit belt with the back of the knife supported
on the rest, and held at the correct angle to grind
along this center line, grind the tang down to just
short of the scribed lines. I use a champagne cork to
supply pressure to the tang right over the area I am
grinding.
Contact wheel diameter
can be anything from 150mm to 250mm.

This little "gizmo" I like using is made from
any hardened steel with two small steel pins soldered
in place for locating into two corresponding holes drilled
into the rest on each side of the contact wheel. The
top edge should be rounded and fine sanded and the front
should extend just past the edge of the contact wheel.
This can be quickly repositioned to either side of the
contact wheel and prevents losing the knife between
the edge of the rest and the belt, and reduces the beating
that your fingers normally take.

The angled end of the tang now roughly ground on both
sides. If you are unfamiliar with tapered tangs - take
a piece of soft wood, taper it and grind out the profile
of the handle. Study it to familiarize yourself where
the thick and thin sections should be - they can be
confusing.

The handle has now been sprayed with "marking blue" to hilite the
next grind for these pics only, which comprises the main straight section of
the handle running
out at the back of the guard.
