Steps for making a secateur

        In reality, the process of making a secateur takes place over a hundred steps… We are going to be more succinct, while tempting to summarize the clearest and most accurate !

The products that we offer you are the representatives of the best of traditional Japanese crafts. These tools are manufactured using specific techniques to forging, rolling and stamping, and are also finished by hand. Those are products that mass production can not make. A blade edge with such a sharp, for your convenience and work efficiency, can not be obtained in industry. Here among other things, that the subtlety of human sensitivity makes the difference.

The party at the other end and corresponding to the blades on each of the portions will be hot forged, in order to form a sort of a rough-shape.

5° Stamping of tips
Forged parts corresponding to the blades will be stamped with patterns, they will then be fired again in order to gain stability – spheroidization – then made to cool down gradually.

7° Grinding of blades
The blades are ground to obtain a similar shape to two halves of a shell, as if we look at a clam shell section.

8° Drilling and tapping
Execution of various drilling, threading, tapping for the location of the screw, the two springs…

9° Temporary screw for adjusting the cutting mechanism
The combining of the two blades, with the establishment of a temporary screw, is going to determine their size. So we are going to cut the outer edge of the cutting blade when necessary.

10° Marking
Drawing of the mark.

11° Correction of gaps
First adjustments of the cutting blade positioned on the side blade.

12° Browning
Depositing of a layer of black oxide on the handle so that it is less susceptible to rust.

13° Resistance and durability
To increase the hardness of the steel, we are going to heat it to 800° C in a special mixture and put it to cool down then in an oil bath. Then reheat it to 200° C.
