A good "Norzon" 50 grit disc should last
for flattening ±25 tangs if it's not used
for any other grinding. I use contact adhesive to
stick them down to ensure they are truly flat. Both
sides of the disc are used allowing me the option
of a sharp disc or slightly dull disc for fine adjustments
to the grind lines.

The tang now "flatter" ground than can
normally be achieved on the platen, alone which
allows a neater fit of handle material and assists
tremendously if bolsters are being used on the tapered
section. Chamfer all holes in the tang and remove
burrs around the edges.

The blade has now been rough ground on a 36 grit
belt. The ricasso is being finished on a 220 grit
200mm diameter disc at 950 r.p.m. (cork not shown).

Mark out the position of the guard, the ricasso
width and shoulder of the main blade bevel. As can
be seen the taper tang must be readjusted to line
up with the back of the guard.

Close but no cigar. You can now finish your blade
grind, the shoulder grind, round the ricasso and
cut the guard notch in the tang. Which reminds me
- you can't replace that cork either - so here's
to your next tapered tang.
