About Products

Our company, SHUNGWEI, has been manufacturing scissors since 1972. The first version of scissors we produced was SW-6101 stationary scissor series, it became a big hit around the world; we sold 1 million pieces of it each year. SHUNGWEI has also produced the prototypes of various kinds of scissors, including but not limited to tailor scissors, barber scissors,fishing line scissors, and multi-function kitchen scissors, the further developed version of all three remained popular till today. At about 2004, low-priced scissors from China swept across the market, causing the high-quality products of our company to undergo a sale decline. Since price cutting competitions were not, and will never be our aim, SHUNGWEI discarded price wars and focused on producing Electrician scissors(Cable scissors,ケーブルシザース), a kind of sophisticated scissors which require professional knowledge and techniques to produce. After succeeding in developing the first version, SW-834, we continued to strive for perfection. Our efforts gain approval around the world; the annual sale of the advanced version of Electrician scissors is around 400 thousand pcs each year.

Product Material

Blade

The material of our scissors' blade is SUS 420J2 stainless steel, purchased from one of the world's leading producers of integrated steel - Japan JFE steel company(JFEスチール). After careful comparisons of varied brands of stainless steel in the market, we decide that the products of Japan JFE possess the steadiest quality, and are therefore the most reliable. Since we set “Providing The Best Quality” as our main goal, the stainless steel of the company becomes our choice for customers.
