I had the pleasure of forging an ultra-lightweight carving
axe for a customer this week, coming in at about 550g.
These smaller axes are such a joy to forge – they are
condensed essence of axe.
This one has a forge welded bit and a mild steel body, the
eye was hot punched.
I started with a short piece of 20 x 40mm mild steel
This was then upset before the edge was split, and a
tapering carbon steel insert was inserted
This was edge piece inserted hot, set and then forge welded
by hand
The eye was hot punched and drifted, the edge for was
refined, and everything was straightened up.
Once forging is
completed, the piece was heated one more time and allowed to cool naturally to
relieve stress- this is called “normalising” and is the first phase of the heat
treatment. After this cycle, the edge is ground to a nearly sharp state and
then the axe is heated once again and finally quenched in oil to harden. After hardening
the axe went in to temper for an hour to remove stress and thus add resilience by
reducing the brittleness of the edge.
Great work, Master.

Hi Josh,
ReplyDeleteDo you know the story of the famous Swedish blacksmiths who were said to quench their blades in virginal premenstrual urine? It was of corse denied, but still.
