KS4020: 4020 Concierge Folding Knife

Kershaw Knives

Like its namesake, known for discreetly and efficiently taking care of tasks for hotel guests, the Kershaw Concierge will take care of all your pocketknife needs—discreetly and efficiently.

Designed by Dmitry Sinkevich, the Concierge has a clean, refined look. The modified drop point blade of 8Cr13MoV stainless steel opens with a flipper and Kershaw's manual KVT ball-bearing system, providing fast and easy one-handed opening. A custom pivot adds interest without detracting from the knife's clean lines.

Yet it's the handle that really takes this exciting knife out of the ordinary. Built of machined G10, it offers a substantial grip and fills even larger hands comfortably. Yet thanks to the crowned finish on the G10 scales, the Concierge still feels slim enough to be an easy everyday carry. For a secure grip, Kershaw added a black, glass-filled nylon backspacer with raised jimping.

Turn the knife over and you'll see Dmitry's unique inset pocket clip. The custom clip rests in a machined-out hollow in the handle—so that it's flush with the handle scale. This pocket clip treatment also contributes to the knife's slimmer feel and easy carry. The blade, liners, and hardware are titanium carbo-nitride coated for a sophisticated look—and is just one more reason why the Concierge will be at home no matter where your tasks may take you.


  • Flipper - May be used with manual or assisted opening knives. Tee "flipper" is a protrusion on the back of the blade that the user can pull back on, or flip, in order to move the blade easily out of the handle.
  • Liner Lock - Locks the blade open during use; one side of the knife’s steel “liner,” the steel plate to which the handle scales are attached, moves into position behind the blade to securely lock it open.
  • Manual - There is no mechanical assist, such as SpeedSafe, used to open the folding knife. It opens the classic, old-school way.

Pocket Clip
Pocket Clip Includes a pocket clip for easy accessibility and a more secure carry.
8CR13 Stainless Steel
8CR13 Stainless Steel Considered a value steel, 8Cr13 steel provides adequate corrosion resistance but with slightly more carbon than AUS-8, it will sharpen up and hold an edge better.
G10 Handles
G10 Handles Formed in a sheet under high pressure by combining fiberglass and an epoxy resin binder. These handles are lightweight and shaped to ensure a solid grip.

Pros: Pocket Clip, Blade Sharpness, Handle Feel, Weight, Ease of Opening, None
Cons: Lock Type
Almost 5 stars
Knife arrived promptly. Comfortable handle, clip holds knife securely, perfectly centered blade, arrived very sharp. Flipper action smooth but could be better. Lock up is poor. Liner lock only catches a very small sliver of the blade, and blade slips free with almost no pressure.

Pros: Handle Feel, None
Cons: Lock Ease of Use, Blade Material
Better than expected
Really surprised with this knife. Doesn’t flip as well as a ZT but it is unassisted and still fires reliably. Mines got a little lock stick and the edge is atrocious but there is no blade play and the fit and finish is easily as good as the American kershaws. With better steel this would be 120 dollar knife.
