Manufacturing Process

1. Blade and EDM

   • 

     1-1
     Cut out the blade material by EDM(Electric discharge machining, aka: wire cutting)
     CAD designing makes cutting
     out into many shapes possible.

   • 
     

     1-2
     Shaping the scissors (cutting out in precise)
     Thinning scissors take about 1.5 hours to shape.
     (Ion exchange resin is used for wire cutting.)
     Wire cutting makes custom scissors possible.

     For example

     • Number of teeth
     • Shape of the slit
     • Narrow or Wide blades

   • 

     Wire cut parts

     

     Punched out material

     

     Forged steel

     

     Cobalt material

2. Punching out screw hole.

   • 
     

     2-1
     Punch out a hole in the center of the screw hole. The hole is less than 0.1mm in precise.

   • 
     
     

     2-2
     Screw hole. Carve out screw out in a funnel shape for the inside screw.

     Stainless steel

     2-3
     Finger blade - open slot.

     2-4
     Finger blade - pierce the hole.

     2-5
     Thumb blade open the hole to 4mm.

     2-6
     Thumb blade open the hole to 5mm.

     2-7
     Clean the whole with a reamer.

   • 

     Open bumper hole

     

      

     

     Piercing

3. Welding

   • 
     
     

     3-1
     Auto polish. Roughly sharpen the blade.

   • 

     3-2
     Welding. Weld the blade and the handle.

   • 

     3-3
     Temporary welding.
     Stainless steels goes to heating process.

4. Polish

   • 

     4-1
     Temporary polishing.

   • 
     
     

     4-2
     Polishing the blade.

     4-3
     Shaping the back side of the blade.

     4-4
     Polish any damaged part.

     4-5
     Polishing finger hole.

     4-6
     Shaping the blades.
     Shape the blade with rough sand papers.

     4-7
     Polishing the front side of the blade.
     Polish to mirror finish.

5. Buffing and adjustment

   • 

     5-1
     Buffing process.

   • 

     5-2
     Check the curve of the blade.

   • 

     5-3
     Check the curve with the gauge.

   • 

     5-4
     Adjustment complete.

6. Finishing and Laser marking

   • 
     
     

     6-1
     Finishing process.

     • Bumper installation
     • Precondition cutting
     • Screw
     • Finger ring installation
     • Engraving the logo and the serial number
     • Cutting test
     • Oiling
     • Tagging
     • In box
   •
