About SUMTHIN
One of China's top 3 clipper blade manufacturers. Precision machining partner to leading professional grooming brands since 2004.
Two Decades of Precision
SUMTHIN (Haining Sanxin Razor & Scissors Co., Ltd.) was founded in 2004 as a precision machining workshop in Haining, Zhejiang — one of China's most established manufacturing regions. Over two decades, we have grown into a 40,000 m² facility with 360 employees, producing over 250,000 blades per day.
Our core expertise lies in precision blade manufacturing across three material platforms: hardened stainless steel, MIM powder metallurgy, and zirconia ceramic. We invested in Metal Injection Molding technology in 2012, launched in-house DLC nano coating in 2015, and introduced 19 ceramic moving blade models in 2016.
Today, we serve as an OEM machining partner to leading US professional clipper brands, supplying precision semi-finished blade components. We also manufacture SUMTHIN-branded finished blades and offer private-label packaging for distributors and Amazon sellers worldwide.
