I’m KAI too! #01

The FACT Magazine crew visited KAI Tawara Factory in Gifu prefecture to observe the manufacturing process of top quality ‘7000 series’ scissors which are used by major manufactures to cut cloth and fabric for car seats among other things. The Tawara Factory produces 500-600 scissors daily.
The "7000 series" are larger than regular scissors and they have their own production line.The production line starts with a laser cutting of a 3mm thick stainless steel board. Stainless steel cut in the shape of scissors, is heated up to around 1050 degrees Celsius for 20 minutes, cooled down, and reheated at 180 degrees Celsius to give the material strength.
The final process is the most important to insure sharpness. Factory workers check the sharpness of each of the blades individually by cutting cloth, adjusting the curve of the blade manually. This final process can only be accomplished with the help many years of experience. It is true craftsmanship.
