further thought on viking blades.
the laminated blades they made were in the iron age.
at that time, bronze swords were superior to basic iron ones, but iron was cheaper to make and repair.
the forging process required to make laminated blades, unknown to people at the time, introduced carbon into the blades, making them more like steel, far superior to iron.
of course modern technology can put a known amount of carbon into iron to make a repeatable alloy of whatever is required for the job.
hand forging laminated steel produces a variable product, possibly inferior to factory made steel.
in the days of the Vikings, if your sword did not bend or snap and your enemy's did you were probably the survivor.
this was never a problem with knives, as they did a different job.
today, quality steel of a known alloy mix is probably a superior material to make good consistent blades from, particularly with modern controlled heat treatment.
an interesting aside regarding metal development is the battle of Agincourt.
we are led to believe that the English won due to use of the English longbow.
this is far from the truth, as the English arrow heads, knwn as bodkins, were soft iron, and mushroomed or bent when they hit French armour plate.
this is because French, german and Italian armour makers had evolved forging to introduce carbon into iron, and their plate was very tough.
the French knights actuall got stuck in the mud and were drowned by their own knd walking on them or were killed by English archers using mallets.
