Ruike P831-SF Folding Knife

This is the second Ruike knife I've bought, having previously got a larger one from a camping/survival store whilst in the far-east a couple of years ago which has been really good. The first thing that struck me was that this knife was smaller than expected, but that's not a bad thing. It feels very solid and is beautifully machined. The lock mechanism is solid and works well and the blade of mine was certainly pretty sharp right out of the box. The only niggle, as others have said, is the placement of the thumb peg which needed to be about 10mm further along the blade to give enough leverage for one handed opening but, that's a relatively minor niggle. Will definitely be getting more Ruike knives in the future I think.

Great service from Heinnie Haynes as always. The knife in question is a pretty thing. The Art Deco lines are very pleasing. It’s a seriously slicer and the ‘almost’ wharnecliffe blade is really rather effective at detailed work. But sadly it does have the flaws many have pointed out. Slightly awkward deployment. But this is due to the liner lock real estate being difficult to avoid more so than the svelte thumb stud. Once mastered its smooth and consistent however. But one shouldn’t have to ‘master’ said process- it should be intuitive. A revision of this knife would be welcome. I’d buy it again gladly with a few improvements as it’s such an attractive piece. The blade was stained in some way as-well. I’ve heard others mention this. I assume it’s a batch issue. The sandvik steel is as ever; perfectly serviceable and hard wearing given this price point.

... if they had skipped the pointless "safety catch" on the lock bar, and put the time and materials into not just (a) proper thumb stud, but (b) a thumb stud on both sides. South-paws beware, you will not be able to open this knife left-hand-only, no matter what

As always HH delivery second to none, had knife in my grubby paws in less than 24 hours from ordering. I know this sounds naff but loved the Packaging, looked like I had just purchased some expensive aftershave. As for the knife itself, yes it is difficult to deploy, yes it wasn't ultra sharp but any knife owner worth his salt would with a little bit of patience sort these issues out, if your looking for perfection you need to buy a Cold Steel Code 4 at over double the price of the Ruike.

What a beautiful and excellent knife to have such a terrible deployment issue. Could not give it 5 stars because of it. I ended up unscrewing the thumb stud about a third of the way and then super gluing it in that position. It raises up the thumbstud so you can open the knife one handed...

Turned up promptly as per usual! Thanks HH. When opening the box and getting the knife in my hand i was expecting to have issues deploying the blade with the problematic thumb stud everyone is going on about in reviews. However i have no issues in fl*~@king the blade out with minimal effort, i found it easier than some of my other folders to deploy. I find you have to f@*%k with your thumb upwards and to the left (10-11 O' Clock). Easy! Great knife and well worth the money for what you get. Sharp out the box (may give it a strop with some compound) and nice in the hand. Glad i ordered it.

Had this knife for a few weeks and liked it but had difficulty opening it after reading the reviews I contacted Mike at MPCustomBlades and had him mod it for me and it's a different story now it fly's open and is much sharper after him mirror Polishing the edge It's so good I may buy another

As the previous review says it is slightly difficult to open up with your thumb. but as a knife maker I have the tools to make it work I opened up the cut out on the show side scale and shaped it to guide your thumb into the stud allowing you to f*k it open with ease

Firstly the bad things about the knife..... 1. the blade had some kind of staining spots on both sides of the blade straight from the box. As though something had splashed on it and not been cleaned off. Like drops of water left on a carbon steel blade. Within half an hour of receiving it this morning I had used ultra fine paper and sanded the blade down. I would rather have a satin finish than horrid spotting. ( I have to say this may only be a problem on my knife and its fine on any others). 2. The knife is not easy to open. For the first ten minutes I actually rubbed the skin off my thumb trying to get it open one handed. Its not that the blade is tight....its actually very smooth. The problem is the positioning of the thumbstud. I found in the end that you have to push the stud along the knife itself....maybe 20 degrees off the centreline. 3. The lanyard hole is very close to the edge of the handle....looks about 1.5mm. This for me is just an aesthetic thing. You may find it fine. Now the good things. 1. Its under £40 2. Its good looking 3. Its well built ( apart from the misplaced lanyard hole ) 4. Lockup is solid. No play up or down and no side to side movement. 5. Blade is well centered 6. Came paper cutting sharp out of the box. So is it worth buying? well....I would say yes. the only thing that may freak you out is the awkward (imho) opening. Me......I'm quite happy to open my knives two handed. I don't need to open them lightning fast anyway. Ruukuu
