About brand

Benchmade Knife Company, Inc. set-up shop in Clackamas, Oregon in 1990 (originally founded in California in 1988). The initial knives primarily consisted of the Bali-Song knives, using a combination of outside vendors and inside processing to build finished products. And like most companies, starting out meant scarce money and big plans, using second hand equipment and limited resources.

Soon, a natural born fortitude and an undying passion to make it right and make it Benchmade, prospered into significant growth. As the product line grew so did the in-house capabilities. We began to acquire new machines and technologies including the first of several lasers, making Benchmade the first knife manufacturer to have such equipment in-house. Open minds and positive attitudes would lead to several more industry firsts over the course of the next several years.

This was only the beginning of Benchmade's breaking of new ground in the manufactured knife markets by using non-traditional materials and modern manufacturing methods in not only building knives better but, inevitably building better knives. The Designer Series was first introduced in 1991 with several custom designs being manufactured. By tapping into the custom knife makers' knowledge and combining it with our manufacturing expertise we were more readily able to offer more contemporary knife designs and innovations to the knife users.

Consecutive years of aggressive growth led to the next logical step in 1996 when Benchmade moved into its own 35,000 sq. ft. facility. A contemporary styled building complete with all of the modern equipment and amenities necessary to manufacture what has become recognized as a higher standard of specialty cutlery.

Today, Benchmade Knife Company, Inc. manufactures knives for a loyal and ever growing following of knife users. As we move into the 21st century we are poised for even more exciting opportunities, innovations and ongoing total world-class quality. Here at Benchmade we employ a simple philosophy- 'Make it cool, make it solid, make it happen and definitely make it Benchmade.'
