Manufacturing process
New Technology-Chemical
etching
Conventional- Grinding
process
 ElectroEtching improves the near
surface chemistry of stainless steel.
Not only does it remove embedded
particles and inclusions, it also improves
the atomic ratios, leaving a
microscopically smooth surface &
edges.
 Grinding the blade.Leads to
scratches in surface, uneven
edges layer& reduction of steel
Hardness.
