It starts with a variety of carefully selected speciality steels, chosen for the properties given to them by their chemical makeup
Those steels are then stacked and arc welded onto a handle, alternating between at least 2 different kinds of steel, ready for the next step, where things can fail catastrophically
Forgewelding; if you go too hot the steels will melt, if you go too cold the steels won’t weld. If you strike too soft, the steels wont weld, if you strike too hard the steels won’t weld, etc, etc, etc
Now begins the difficult process of forging the blade to shape, distorting the steel layers into their final pattern
The steel at this point is too soft to cut properly, quenching it at the right temperature fixes that problem
Grinding to the final size and shape, carefully making sure that nothing overheats or the steel will go soft again. Much knuckle skin has been lost here
Finally fitting and shaping the handles from a variety of durable and elegant hardwoods
And so, after a great deal of work a knife is born
