One piece key tool vs folding multitool

Updated: October 2026

You are stood between a flat plate on the keyring and a folding set that promises more bits. The useful split is weight and whether anything locks. This page puts the twelve amazon.co.uk listings in our [multi tool key ring comparison](/hub/lawn-and-garden-equipment/multi-tool-key-ring) on one side or the other. Shard versus DoohicKey is the wrong versus for this URL, because both are plates. That pair is on the [best keychain multitool](/hub/lawn-and-garden-equipment/multi-tool-key-ring/sub/multi-tool-key-ring-best) page. Peter F. wrote this on 22 October 2026 from saved listing fields.

Which listings are which shape

One-piece means no pivot. The Gerber Shard is 16.8 g at about £10.00, with flat and cross drivers, a pry, and a lanyard hole. The Nite Ize DoohicKey is about 9 g at about £6.00, with a flat driver, a box cutter, imperial hexes, and a spring clip. The Orbitkey V2, about 13.6 g, is an organiser insert. The Clip KT, 21.2 g at about £17.95, unclips and is still a plate. Folding means parts that swing out. The GOWEILE is about 105 g at about £8.69, with flat and Phillips drivers, a star, and a hex. The Uadme is about 100 g, with 4.5 from seven reviews. The Moineefo is 15 g, with a stated fold-out blade, locking positions, and no reviews.

Pocket, clip, and grip

A plate disappears into a bunch of keys until you need the notch, and it snags when the silhouette is wrong. FLRMINGE reviews say the key shape is longer than a short latch key, so it catches pocket cloth. Three colours are one shape. The DoohicKey's spring keeps it on the keys. UK review notes include a spring gone after about eight months. The Clip KT unclips for grip, which is what about £17.95 is buying. About 105 g beside a 9 g DoohicKey is the whole argument.

Bits versus openings

The folders earn their weight when the screw is the job. GOWEILE and Uadme name more than one driver size, including cross or Phillips, slot, star, and hex. The Shard is the plate that names a cross driver. The DoohicKey gives you three imperial openings and a flat driver, and it will not become a Phillips. GOWEILE reviews say some bits needed a file before they worked. The Moineefo is the listing that states a fold-out blade. The buying guide puts that check before the tally.

The condition, then one recommendation

The Moineefo's 15 g would beat the GOWEILE on the scales, and the listing then states locking positions. GOV.UK's exception is a non-locking cutting edge of no more than 3 inches, so a stated lock sits outside it. Why this is not advice is on the UK carry rules page. The 7 cm figure is the whole tool, and there are no reviews. Choose the Shard for a cross driver on a plate, or the DoohicKey at about £6.00 for the clip and imperial hexes. Choose the GOWEILE when you want several driver bits and will carry about 100 g. Do not choose the Uadme on seven reviews, or the Moineefo, until you have read the lock line.

Common questions

When is the one-piece plate the better pocket object?
When the tool has to live on the keys you already carry, and the jobs are a bottle, a parcel nick, a pry on a staple, or one driver. The DoohicKey is about 9 g and the Shard is 16.8 g. There is no pivot to loosen and, on those two listings, no lock stated. You give up the extra driver sizes the folders print. For a plain ring, that trade is the one this set supports with thousands of reviews.
When is a folding set worth about 100 g?
When you need large and small flat and cross drivers, or a star bit, and you will carry the weight on a bag clip rather than pretend it is another house key. The GOWEILE at about 105 g and about £8.69 is the folder with 53 reviews. Expect fiddly bits. If 100 g already feels like too much beside your keys, the plate was the answer.
Why do reviews say a key-shaped plate catches cloth?
Because the FLRMINGE shape is longer than a short latch key, and the shared reviews say so, along with sharp edges. It looks like a key, which is why people buy it as a gift, and it does not disappear like a 9 g clip-on plate. Gold, black, and silver are the same shape with one 237-review pool. The catch is the shape, not the colour.
Does every folder include a knife?
No. The GOWEILE and Uadme listings lead with drivers. A knife or a blunt blade shows up in reviews, not as a measured edge in the bullets. The Moineefo does state a fold-out blade and a lock. If a blade is something you are trying to avoid, stay with a plate that does not list one, and still read the DoohicKey's box-cutter line before you assume no blade means no edge at all.
Where does a 15 g folder with a stated lock sit?
On the folding side of the weight chart, and outside the non-locking exception as GOV.UK describes it. The 15 g figure is the item-weight field, unchecked by reviews. The 7 cm highlight is the tool, not the cutting edge. It is not the same decision as a 105 g driver folder. Read the carry page before you treat the low weight as the winning feature.
Are the three FLRMINGE colours three shapes?
No. They are one key-shaped plate in three finishes, one shared 4.4 from 237, and a record of colour mix-ups. Count the shape once. Pick the ASIN that matches the colour you want, and do not add the review counts.
