Kershaw Collateral – 3.4" D2 Assisted Flipper Knife, Carbon Fiber

The Kershaw Collateral combines sleek, modern styling with innovative assisted-opening technology. Its most distinctive feature is the hidden flipper, which disappears into the handle when the blade is fully open, creating a clean, uninterrupted profile.

The 3.40-inch D2 tool steel blade features a drop-point profile with a two-tone satin finish and sanded flats. D2 offers excellent wear resistance, toughness, and edge retention, making it a capable choice for everyday cutting tasks.

Kershaw combines SpeedSafe® assisted opening with KVT ball-bearing washers to provide exceptionally smooth blade deployment. A sturdy frame lock keeps the blade securely locked during use, while the titanium carbo-nitride stainless steel handle features a carbon fiber front insert for added contrast and a premium appearance.

A custom backspacer and reversible tip-up pocket clip complete the design, allowing right- or left-handed carry.

Knife Depot Take

Our Take: The Collateral is one of those knives where the details really make the difference. The hidden flipper gives it an unusually clean profile when open, while the combination of SpeedSafe assisted opening and KVT ball bearings makes deployment remarkably smooth. Add a D2 blade, carbon fiber accent, and frame lock, and you get a modern EDC that looks as good as it performs.
