Excellent mini keychain/multitool knife!
I have the Boker Plus version of this knife with orange scale. I like, and use it so much I decided to get an extra one in case something happened to it. I was disappointed to discover that Boker has discontinued this model! Luckily, I came across this one by Ruike that is exactly the same model and looks to be made by the exact same manufacturer! I bought the one with the olive-drab green scales this time. The knife arrived with a very sharp main blade -- a sharpness that rivals my own sharpened and stropped knives! That was truly a surprise because I've become so accustomed to having to sharpen and strop every new knife I buy. This knife needed absolutely no touching up. The hook blade (seat-belt, strap/cord cutting, package opening blade) was perfectly sharpened too! Again, I am used to having to touch up newly purchased edges, but this one needed nothing done to it! The size and usability make this my perfect EDC knife: -The main blade is longer and thicker than a Swiss Army Classic, meaning it's also stronger and will take harder use. -The cap lifter/bottle opener works great and gets a lot of use for opening bottles. -The hook blade is probably the tool I use most. It opens plastic snack food packages (potato chips, beef jerky etc.) with a nice, clean, straight cut, freeing me from the worry of food flying all over the place by trying to pull the seal apart with my bare hands! It also works perfectly for opening those white and blue Amazon envelope packages with the perforations that never seem to want to tear open where they're supposed to. One swipe of the hook blade and you're into your goodies! -The flat-tip screwdriver gets more use as a small, light duty pry bar than an actual screwdiver and is a welcome handy tool to have on hand. I'd recommend this knife to anyone looking for a mini Swiss Army type knife that packs a lot of punch for its size and has great, functional tools in a small, elegant package. If they offered more color choices for the handle scales I'd be handing my money over to get my hands on them! If you're on the fence about getting one, consider this your final push to go ahead and get it. You won't be disappointed, and the company will hopefully continue making this model for many years to come!

Keychain EDC
I needed a small minimalist EDC utility tool to clip on my keychain, as I don't have room for a knife or multitool in my pockets with summer coming. This fits the bill. The utility 'blade' has the most useful feature- a hook for opening packaging. I'm sure the bottle opener and screwdriver head will get used at some point too. The knife blade is good steel, big enough to be actually usable and very sharp. The handle feels nice and everything appears to be good quality with good tolerances. I opted for the non scissor version of this model for lessened weight and I'm glad I did. Good alternative to the Victorinox rambler if you want a more usable blade.

Perfect for small every day carry pocket knife
High quality! Small and unobtrusive while carrying it in my front pants pocket but very useful. Excellent tools. Sharp blade! It has cut open a lot of Amazon packages plus more for me. Definitely recommend it.

Promising alternative for Swiss Army Knives that fills a gap in the smaller sized knife universe
I went through a period where folding knives and multitools couldn't be heavy and mean enough. Now, I have rediscovered the simplicity and quality of the Swiss Army Knife. I was curious about this clone because it seemed to be the perfect size, falling between the tiny "rambler" (on the left) and the larger "waiter" on the right, both of which I keep on my desk. To the right of the waiter, I have added a "Compact", which is the more common 91mm. This Ruike, however, seemed to be an ideal in-between size: a bigger and sturdier knife and scissors than the rambler, but still smaller than the relatively small waiter. I am not disappointed. It has a lot in common with Swiss Army Knives: it looks and feels well-made and sturdy, it has a satisfying "snap" when you open or close it, it doesn't wobble, and it is sharp out of the box (although not as sharp as a Victorinox). It is heavier, even than the waiter, and because its three tools open to the same side, it is also fatter; however, there is a case to be made for a little more heft in the smaller knives. We'll see how it stands up to the ruthless abuse it gets at my desk (ie, cutting paper and the occasional hangnail), but I am pleased with it so far.

Disappointed
I was very impressed with build quality of this knife. After a few weeks of using it I've become disappointed. The blade ws super sharp and impressive. The edge has dulled and pitted under light general use... cutting string, and plastic hay netting. I'll probably go back to the old standard Victoria swiss knife... last for years !

Great little blade. Overall well built.
Overall great! I have it for a year with my keys, flashlight AND whistle for a year AND cant complain. The blade Is better than a Victorinox sd. Would buy it again.

Hervorragend verarbeitet und sehr scharf, es wackelt nichts. Hat für die Größe sinnvolle Werkzeuge und ist gut am Schlüsselbund zu befestigen.

Ottimo coltellino, non vi aspettate di fare bushcraft!!!! E' un piccolo gadget ma può essere molto utile quando non si hanno delle forbici una lama un apri bottiglie o un piccolo giravite piatto, inoltre ha una lama per tagliare cavetti. Direi che in tasca te lo dimentichi ma può rivelarsi molto utile. Ottima fattura e robustezza. Lo consiglio a chi non vuole coltellini pesanti che ciondolano nelle tasche e danno fastidio.

Discret et efficace couteau de poche. Je l'utilise au quotidien depuis des années et il m'a dépanné de très nombreuses fois. Un petit nettoyage / huilage de temps en temps, c'est tout ce qu'il demande. Le tranchant résite, bien qu'il soit souvent mis à l'épreuve. Il est d'une taille idéale - peu fréquente - pour servir de porte-clé et permet des choses que bien des couteaux plus petits sont incapables de faire (notamment les petits Victorinox compacts). Le coupe-ceinture est idéal pour ouvrir des gros colis. Je recommande ce modèle (qu'on trouve en plusieurs variantes , 1, 2 ou 3 lames et couleurs ou matériaux) chez plusieurs fabricants (RUIKE et Böker notamment).
