“Eyes On” report from Alexander Crown on the Benchmade Boost 590.

Us our coupon code for fuck’s sake. You don’t know what we had to do to get it — some things won’t wash off.

I was lucky enough to be sent one of Benchmade’s Boost folders for an initial look. Stay tuned for a long-term review in the coming months.

Benchmade is no stranger to folding knives. I carried a Griptilian many, many years ago while on active duty and it’s nice to see that their quality hasn’t declined. The Boost family of knives comes in several lengths and finishes; here we’ll examine the 590.

The Boost is an everyday carry folder featuring Benchmade’s assisted opening, AXIS® Assist. The handle of the knife is made of Versaflex and has a rubberized texture for added “grippyness” to help maintain control when you flick the knife open. The blade locks with the familiar Benchmade slide mechanism and also has a “lock out” feature that won’t allow the knife to deploy when engaged, or if engaged on an open knife won’t let the blade close. This is a nice touch for some of the more clumsy wielders. The handle has also incorporated an ambidextrous mount for the deep concealment pocket clip, and a lanyard hole.

The Boost’s blade is CPM-S30V, widely regarded as some of the best blade steel available. CPM-S30V is 58-60 HRC, making it an excellent choice for the daily grind (see what we did there?). Benchmade fitted the 590 with a drop point and a 3.7” long cutting surface. The blade’s thickness is .12”, and it has an ambidextrous thumb assist.

4.6 ounces

Out of the box the Boost is razor sharp, as expected. The contours of the grip make it feel comfortable in the hand, and the tackiness of the grip is welcomed. At 4.6 ounces the Boost is a little heavier than I prefer for an everyday carry knife, but the assisted opening and lock are a fair trade-off. I look forward to keeping this one in my pocket for the next couple months.

Benchmade Boost 590 features are as follows, per the manufacturer.

Benchmade Boost 590 Description and Specs:

The Benchmade website description is lackluster and anemic at best, though the specs are spelled out clearly.

[The Boost 590] Dual Durometer handles greatly increase grip performance while maintaining strength on this fast-action assist. Made in USA.

The description on Amazon (where it has 4.5 stars out of 5, with 20-some reviews as of this writing) is much better.

HIGH-QUALITY: The CPM-S30V stainless steel blade is extremely well-balanced, offering superb edge qualities and rust resistance. The Grivory and Versaflex dual durometer handle greatly increases grip while maintaining strength.

WELL-DESIGNED: The Boost 590 is a fast-action assisted-opening knife. It can be opened and closed quickly with either hand.

ALWAYS READY: The 590’s quick, one-handed opening makes it easy to hold and use. The reversible pocket clip offers ultimate accessibility.

VERSATILE: The Boost 590’s drop-point, utility blade style and all-around functionality make it ideal for everyday carry.

GUARANTEED FOR LIFE: Benchmade’s Limited Lifetime Warranty and LifeSharp Service keep your knife in the best condition. If your knife needs repair or sharpening, Benchmade will take care of it. Available for knives purchased from an authorized dealer.
