Benchmade Barrage 581BK-04: Frequently Asked Questions

Answers to the most common questions about the Benchmade Barrage Redstone Richlite (581BK-04).

How does the AXIS Assist spring-assisted deployment work?＋

AXIS Assist uses an internal torsion spring that engages when you nudge the dual thumb studs outward. The spring takes over to snap the blade fully open, where the AXIS Lock bar locks it securely in place. An integrated safety switch on the handle spine prevents accidental spring deployment in your pocket.

What is Redstone Richlite material?＋

Richlite is a dense, high-performance paper composite laminate bound with resin. The Redstone finish delivers a rich, warm wood-like appearance with high durability, moisture resistance, and smooth tactile comfort in hand.

What steel is used for the 581BK-04 blade?＋

The 581BK-04 features CPM-S30V powder metallurgy stainless steel hardened to 58–60 HRC with a Cobalt Black Cerakote coating, providing an optimal balance of edge holding, toughness, and corrosion resistance for daily cutting tasks.
