Four Finger Stainless Steel Foldable Knuckle Dusters

The Four Finger Stainless Steel Foldable Knuckle Dusters is made from four solid stainless steel rings linked edge to edge by small pivot pins. Swing the row out and it opens into four round finger openings; fold it back and the rings stack into one compact cylinder that rests neatly in the palm. The surface is brushed steel with polished bevels along every edge, giving it a clean, well-finished look that catches the light without ever looking flashy.

Each ring opens to 23mm inside, with a 33mm outer diameter and a folded stack about 26mm thick, and the whole piece comes in at about 88 g. That is a genuine, reassuring weight for something this size — it settles into the hand with a solid, substantial feel rather than a hollow one. The pivots sit flush with the ring surfaces and the edges are rounded, so there is nothing to catch or bite into the fingers whether the row is open or folded away.

Closed, it is a palm-sized steel cylinder that slips into a pocket and stays out of the way; open, it swings into a row that spans all four fingers at once. The fold is the satisfying part — a smooth swing from flat row to stacked cylinder, easy to open and close whenever you like. For everyday carry, it is a solid steel piece you can fold away the second you are done, then pull out and open again when you want it back on your fingers.

Key Features

• Folds flat in one swing: the four rings pivot from an open row into a single stacked cylinder, so it pockets small and opens fast
• Solid stainless steel: about 88 g of solid steel with a brushed finish and polished bevels — weight you notice, not a light fashion ring
• Four 23mm openings: round holes sized for most adult fingers, with rounded edges that stay comfortable whether open or folded
• Palm-sized when closed: the folded cylinder measures 33mm across and about 26mm thick — small enough to ride in a pocket unnoticed
• Flush pivot pins: the hinges sit level with the ring surfaces, keeping the piece smooth in the hand in both states
• Low-maintenance finish: stainless steel takes daily handling in stride; a quick wipe keeps it clean

Frequently Asked Questions

Q: How does the folding work?

The four rings are joined edge to edge by pivot pins, so the row swings open flat and collapses back into one stacked cylinder. It becomes a quick swing from flat to stacked once you get the motion down.

Q: Will it fit my hand?

The 23mm openings take most adult fingers, and the row spreads across all four at once. If your fingers sit between sizes, the rounded edges make a snug fit more forgiving than a hard square frame.

Q: How does the weight feel in use?

At about 88 g it is a genuinely solid piece — heavier than any ring you wear, but short of feeling like a tool in the pocket. The mass sits centered in the palm whether the row is open or folded.

Q: How should I care for it?

Wipe the stainless steel with a dry or slightly damp cloth and keep it out of prolonged damp. The brushed finish hides light handling marks, and avoiding abrasive scrubbing keeps the polished bevels bright.

Q: How pocketable is it when folded?

Folded, it forms a cylinder about 33mm across and 26mm thick — roughly the footprint of a large stack of coins. It rides in a pocket or pouch without snagging, since the pivots sit flush when closed.

Four stainless steel rings on flush pivot pins — the Four Finger Stainless Steel Foldable Knuckle Dusters opens to four 23mm finger openings at a 33mm outer diameter, folds into a cylinder about 26mm thick, and weighs about 88 g, so it pockets small and opens fast whenever you want it out.
