Benchmade Boost 590 – 3.70" Satin CPM-S30V Drop Point Assisted Opening Folding Knife
The Benchmade Boost 590 is a full size EDC folding knife built around a 3.70" satin finished CPM-S30V drop point blade and Benchmade's AXIS Assist mechanism with an integrated slide safety. The handle pairs a dark gray Grivory core with a black Versaflex overmold, the dual durometer construction that gave the Boost line its grippy, shock absorbing feel in hand. Benchmade has discontinued the Boost 590, and this page stays current for owners, collectors, and anyone researching the model. Going Gear is an authorized Benchmade dealer.

Frequently Asked Questions
What is the blade length of the Benchmade Boost 590?
The Benchmade Boost 590 (BCM-590) has a 3.70" satin CPM-S30V drop point blade, a full size cutting edge that still carries comfortably thanks to the knife's 4.59 oz weight.
What steel does the Benchmade Boost 590 use?
The Benchmade Boost 590 uses CPM-S30V, an American made premium stainless steel hardened to 58-60 HRC. S30V holds an edge well, resists corrosion, and sharpens back to a fine working edge without special equipment.
Is the Benchmade Boost 590 an automatic knife?
No. The Benchmade Boost 590 is an assisted opening knife, not an automatic. Its AXIS Assist mechanism finishes opening the blade after you start it with the thumb stud, and an integrated slide safety locks it closed. Assisted openers are legal in more places than automatics, but knife laws vary, so always check your local regulations.
What is a Blue Class Benchmade knife?
Blue Class was Benchmade's label for its everyday carry line, and the Benchmade Boost 590 was sold as a Blue Class model. Benchmade has since retired the color class system, but Blue Class knives like the Boost 590 were built in the same Oregon City, Oregon factory as the rest of the lineup.
What is the difference between the Benchmade Boost and the Benchmade Freek?
The Benchmade Boost 590 uses AXIS Assist with a dual durometer Versaflex and Grivory handle, while the Benchmade Freek 560 family uses the manual AXIS lock with a similar dual durometer grip. The Freek carried the concept forward after Benchmade discontinued the Boost line.
Does LifeSharp cover the Benchmade Boost 590?
Yes. Benchmade's LifeSharp service covers the Benchmade Boost 590 for the life of the knife, even though the model is discontinued. Benchmade will clean, oil, adjust, and resharpen it to a factory edge for free.
Where can I buy the Benchmade Boost 590?
Benchmade has discontinued the Boost 590, so remaining stock is limited to dealer shelves and the secondary market. Going Gear is an authorized Benchmade dealer and carries the current Benchmade lineup, including modern assisted and AXIS lock alternatives.
