The glowing blade slugs are forged by a
pressure of 300 to.
After this is done the steel is tempered
(glow treatment) cooled down and hardned
with water or oil.
In this forging steps the steel receives its
shape and the destinated molecular struc-
ture. But in this stage the steel is still so
hard and brittle that you cannot use it as a
blade-steel. Through making it glowing
again, the steel looses parts of its hardness
and the destinated quality of the blade is
reached: Temper and elasticity, easy to
be resharpen but also high cut quality.
At the end the blades will be cleaned and
polished or satined by manual labour and
then in the last stage when the LAGUIOLE
is already assembled the blades will be
fine sharpend. |
