Ninety dollars usually buys a good blade and a lock nobody remembers. Demko spent the Shark-Cub’s budget the other way around: a 2.7-inch blade in mid-tier Japanese stainless, and the Shark Lock up top, the spine-mounted mechanism that built the brand’s following on much bigger, pricier knives. That split defines the knife, and it’s deliberate.

Demko calls it the economical model, the one built to keep the brand’s quality and durability intact at a lower rung of the line. No flagship steel, no milled scales, no ceremony. Just the lock, done properly, in a knife sized for actual pockets.

Demko built the Cub to answer buyers asking for a smaller, more compact folder, and it lands at 6.8 inches open with a 4.1-inch handle. Glass-reinforced nylon scales ride over steel liners, the whole thing weighs 3 ounces, and production runs through Taiwan.

Everything else on the spec sheet serves that one decision, so start with the lock.

The lock carries the argument

A spring-loaded bar rides along the top of the spine, and its front end drops into a notch on the blade tang when the knife opens. Pull the bar back with a thumb and the blade swings free; let go and the spring drives it home again. Load from a hard cut runs into that bar and the tang behind it, not into a thin liner tab flexing sideways.

Demko’s own film shows the lock cycling and the blade shapes side by side:




Here’s why that lands at $89.99. Folders at this price usually lock with a liner, a frame, or a crossbar borrowed from somebody else’s parts bin. The Cub runs Demko’s own mechanism, the same Shark Lock fitted to the bigger AD20.5 line, and the pivot spins on caged bearings with the Demko name molded around the pin.

Expect to cycle it at your desk, too. There’s no wrist flick or button timing to learn: the thumb draws the bar, the blade moves, the spring seats it home. Mechanisms this tactile get played with, and the bearing pivot makes the playing smooth.

The steel is where the saving lives

AUS10A is a Japanese stainless that sits in the middle of the pack, and Demko’s spec sheet doesn’t pretend otherwise. It takes a fine edge quickly on basic stones, shrugs off pocket sweat and rain, and gives back edge life sooner than the harder steels rivals brag about at this price. The money went to the lock instead.

Maintenance stays cheap, too. AUS10A touches up on the same ceramic rod or basic stone that handles kitchen knives, and it won’t chip out the way harder, more brittle steels can when a staple jumps out of a shipping box.




The stonewash finish hides the scuffs a working edge picks up, which suits a knife built to be used. At 2.5mm thick, the stock stays thin and slicey, no pry-bar pretensions.

Three blade shapes, one price

Shark Foot leads the line in the photos for a reason: a straight edge and a low, angled tip make it the utility pick, happy draw-cutting through cardboard and cord. Slicer Shark brings a deep-bellied profile built for food prep and long slicing strokes. Clip Point is the classic, with the fine tip for detail work.

All three run $89.99, all three showed in stock at Demko this week, and there’s no strike-through price doing theater next to any of them. Orders go straight through the maker’s store, the same page whichever blade you pick, which keeps the choice about shape.

Built to disappear in a pocket

Deep carry is the other half of the design. The clip buries the knife low in the pocket and swaps to either side for left-handed carry, and the smooth GRN scales slide past pocket seams instead of shredding them. A 4.1-inch handle still gives four fingers somewhere to be, which plenty of small knives get wrong.

Three ounces, clipped in the morning, forgotten by nine.

GRN is how the price stays put. Scales come molded instead of machined, and the steel liners underneath keep the handle stiff, so the structure stays real where it counts and cheap where it doesn’t show.

One more detail from the maker’s photos: the oval slot cut through the Shark Foot and Slicer blades gives a thumb its purchase for opening, so there’s no stud to snag. The Clip Point adds a thumb stud anyway, because tradition.

Buy it for the lock

So here’s the call. If you’ve handled an AD20.5 in a shop and walked away over size or price, the Cub is your knife: same lock, half the footprint, $89.99 out the door. If your daily cutting is boxes, cord, straps, and the odd apple, AUS10A covers it and sharpens back up in minutes. As a first Demko it makes sense, too: the mechanism is the brand’s calling card, and the Cub deals you in without the big-knife bulk.

Steel-first buyers should step up to the AD20.5 in S35VN and pay for the harder blade. Anyone who needs a long, hard-use edge should skip the Cub entirely. For the rest of us, the lock wins the argument at this price.
