The best-selling original Benchmade 3550 Mel Pardue automatic knife was slightly modified in 2016--producing the new and improved Benchmade Stimulus auto knife. With increased reliability and improved access to the enlarge firing button, this true utilitarian tool certainly doesn't sacrifice function for form. This Benchmade black class model, the 3551, features a single edged spear point style blade in a satin finish and symmetrical black anodized 6061-T6 handle scales with an integrated safety on the spine near the location of the firing button. This classic automatic knife aims to please with its American-made 154CM stainless steel and the handle offers a slim profile and ergonomic grip. The pocket clip is designed for tip up carry only. Made in the USA.

    I have to agree with the other reviewer. This is a very well made knife. Feels great in your hand, sharp right out of the box and light. Thanks Blade ops for the quick service and a great product.
