A surprisingly well made pocket knife! I love it
As a multitool aficionado, I came across this beauty by just typing "pocket knife with scissors". It didn't have many reviews at a time but looked very nice and the price point was great, so I decided to pick it up.The tool came smaller than I expected but not too small to fit in my hands and not too big to be on a keychain. Tool selection is well thought out and more than enough for everyday carry in your pocket.Blade is made of better steel than what you usually see on the Swiss/SAK. Obviously thicker and more durable.I really like the Scissors here because it's way easier to deploy and also personally they cut better than the SAK's (probably on par with the 91mm SAK scissors but definitely way better than the Swisstool Spirit's, you'll know what I'm talking about if you have a Spirit yourself).Lastly, one of my all time favorite tool combos, the flathead screwdriver - belt cutter - bottle opener. I have a Victorinox SAK Manager that has almost the same tool integration like this one, but Ruike does a better job here. Bottle opener works great and the flathead is meant to use on medium sized screws. I never had a chance to test the belt cutter, but it works wonderful on ropes.In the photos you can see other tools laying next to each other for size comparison (from left to right: Gerber Dime, Ruike S31, Victorinox Fieldmaster, and Leatherman Wave+). I love them all and they are good for different purposes but man, the Ruike does stand out compared to other well known brands. What it has to offer, it does very well in every category.I swear I can talk about this beauty all day. Overall, such a well made little gadget to have. I can't believe how underrated this company is because they're not that well known in the EDC community. Such a big surprise from a Chinese company because there are so many trash ones out there that I don't trust lol. Now I'm inclined to buy more of these to gift my family and friends.

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.

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.

All the knife I need to carry around and shie
Does what I need. No frills & no gadgets just a good knife. Nice blade, good scissors and a way to open hard-to-open pistachios…

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

Piccolino ma potente
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.

Excellent raport qualité -prix-taille polyvalence
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).
