DIFFERENCE BETWEEN STALEKS NIPPERS AND OTHER BRANDS

This is my experiment that lasted 2 days (48 hours). There were 4 nippers: 2 from HBT www.healthbeautytools.com.au Staleks and 2 others.


I immersed the nippers in a disinfecting solution for only 48 hours. after 2 days, I took the nippers out of the solution, dried them and checked: the Staleks nippers worked just as well, but the other 2 nippers stopped working and rust formed on their surface.

Reasons for the outcome:


High-Quality Stainless Steel (AISI 420 or 40X13): Staleks nippers are made from AISI 420 stainless steel or 40X13, a high-alloy stainless steel with a high chromium content (around 13%). Chromium forms a passive oxide layer on the steel’s surface, which protects it from corrosion and rust, even when exposed to harsh disinfecting solutions. The other nippers likely used lower-grade steel with less chromium, making them prone to rust.


2.  Advanced Surface Treatment: Staleks nippers undergo multi-stage polishing, often with GOI paste, which enhances their corrosion resistance by creating a smoother, less porous surface. This reduces the likelihood of chemical penetration from the disinfecting solution. The other nippers may lack such treatment, leaving their surfaces more vulnerable to chemical attack and rust.


3.  Thermal Treatment for Durability: Staleks nippers are thermally treated in vacuum ovens, which improves the steel’s hardness (HRC 48-51) and structural integrity. This process ensures the metal remains robust and resistant to degradation, even under prolonged exposure to disinfectants. The other nippers may not have undergone similar treatment, leading to material breakdown and rust.


4.  Design for Sterilization: Staleks nippers are specifically designed to withstand repeated disinfection and sterilization (e.g., in autoclaves or dry-heat ovens) without losing functionality. Their hinges are polished and treated with abrasive paste for smooth operation and corrosion resistance, ensuring they remain functional after immersion. The other nippers likely had less precise hinge construction or lower-quality joints, which could seize up or corrode when exposed to the solution.


5.  Disinfectant Compatibility: Staleks recommends avoiding highly corrosive agents like acids or alkalis for disinfection, but their nippers are engineered to handle standard disinfecting solutions used in nail salons. The disinfecting solution used may have been too aggressive for the lower-quality nippers, causing rust and mechanical failure, while Staleks’ superior materials and construction held up.


In summary, the combination of high-chromium stainless steel, advanced polishing, thermal treatment, and sterilization-compatible design makes Staleks nippers highly resistant to rust and damage in disinfecting solutions, unlike the other nippers, which likely used inferior materials and lacked these protective features.


Always ensure the disinfecting solution is appropriate for stainless steel tools to avoid unintended corrosion, even with high-quality instruments.
