The 590BK carries a black coated CPM-S30V drop point blade on the same black and gray dual durometer handle as the satin blade Boost 590.\u003c\/p\u003e\u003ch3\u003eWhat is the blade length of the Benchmade Boost 590BK?\u003c\/h3\u003e\u003cp\u003eThe Benchmade Boost 590BK (BCM-590BK) has a 3.70\" black coated CPM-S30V drop point blade with a plain edge, matched to an 8.52\" overall length and a 4.59 oz carry weight.\u003c\/p\u003e\u003ch3\u003eWhat steel does the Benchmade Boost 590BK use?\u003c\/h3\u003e\u003cp\u003eThe Benchmade Boost 590BK uses CPM-S30V premium stainless steel at 58-60 HRC. The black coating adds glare reduction and extra corrosion protection on top of S30V's already strong stainless properties.\u003c\/p\u003e\u003ch3\u003eIs the Benchmade Boost 590BK an automatic knife?\u003c\/h3\u003e\u003cp\u003eNo. The Benchmade Boost 590BK is an assisted opening knife. The AXIS Assist mechanism completes the opening after a push on the thumb stud, and a slide safety keeps the blade locked closed. Assisted openers are treated differently from automatics under most knife laws, but always confirm your local rules.\u003c\/p\u003e\u003ch3\u003eWhat is a Blue Class Benchmade knife?\u003c\/h3\u003e\u003cp\u003eBlue Class was Benchmade's name for its everyday carry tier, and the Benchmade Boost 590BK was a Blue Class model. The label has been retired, but these knives came from the same Oregon City, Oregon production line as Benchmade's current knives.\u003c\/p\u003e\u003ch3\u003eDoes LifeSharp cover the Benchmade Boost 590BK?\u003c\/h3\u003e\u003cp\u003eYes.
