How Steel Quality Affects Sharpness & Precision Of Manicure Tools
Date Posted:15 December 2022
Today, most manicure sets are made of stainless steel, so it's easy to believe that any stainless steel nail kit is decent quality. However, there are over 3,500 grades of steel which determine strength and durability of the cutting edge. Only stainless steel of particular quality can guarantee sharpness and precision of manicure tools so they last a lifetime. Let's learn more about types of steel used in the best nail instruments.
What Is Steel
Also, make sure you are not allergic to these elements since nickel and chrome can cause reactions on sensitive skin.
You may have come across the terms “hot forging” vs “cold forging” describing the quality of steel. Forging is a metal shaping process and depends on the temperature used to mould a metal piece into a certain shape.
With hot forging, the metal is heated almost to its melting point so it changes its molecular structure. The extreme heat increases the hardness of steel and makes it less likely to fracture. The higher the hardness, the longer the instrument will retain its sharpness of the cutting edge without the blades becoming dull.
Hot forged manicure tools are considered to be of the highest quality.
In cold forging, the process is done at (or nearly) room temperature and does not cause any structural changes of steel, thus maintaining its original characteristics. Cold forging production involves several mechanical processes, such as bending, coining and punching, which are most often performed by industrial machines. Therefore, cold-forged steel is more economical but less strong.
All That Glitters Is Not Gold
Unfortunately, manufacturers of cheap manicure sets rely on limited public awareness about stainless steel and often use low-grade materials in their steel production which results in quick loss of cutting properties. So even if their packaging claims “stainless steel”, this does not necessarily translate into decent performance. Nail clippers, manicure scissors and nippers made of poor quality steel become blunt after just a few uses, tear the nails and cuticles making them prone to dangerous infections.
