- May 10, 2018 -

The electric furnace replaced the old forge, and the precise pyrometer replaced the way of visual measurement of temperature.

All the tools are made of purchased steel bars. These steel bars are forged - hammering to the desired thickness and shape after heating. Forging is a slow process, and steel bars may be recycled several times during the period.

Butterfly knives, which belong to more powerful cutting tools, such as some butterfly knives in the shears, can pierce the thin steel plates.
