The body and materials
The Ruike P843-W is a sturdy folding knife, with 3.1mm 12C27 steel blade treated cryogenic.
The handle is in G10 with a particular knurling that guarantees excellent grip in any situation. (The handles of RUIKE knives are built with a mixture of fiberglass and resin, which give the knives the ability to resist intense forces and prevent scratches and abrasions).







The color of the model in my possession is Military Green but the Black version is also available for purchase.





In hand, the P843-W is well balanced and comfortable to use. The sensation is of absolute robustness. The thicknesses are abundant and despite this the weight is still contained.



























The ergonomic shape guarantees a firm and at the same time comfortable and safe grip.



















Thanks to the Thumb Flip and the Flipper on the back it is possible to open the knife with the thumb or forefinger, both with the right hand and with the left hand, with extreme ease even when wearing gloves.















The P843-W is equipped with special bearings with carbon steel balls with high hardness and wear resistance that make the opening and closing operations fluid and easy.
The blade lock is guaranteed by two systems: the classic "Liner lock" and the "Thumb-UP Safety Lock". The latter is located on the back of the knife and can be easily operated with the thumb by simply moving the lever forward. When the "Thumb-UP" lock is inserted, the blade cannot be closed because the mechanism will block the action of the Liner Lock. This prevents the blade from accidentally closing on the fingers while using the knife.











The lettering is excellent: on the blade are the company logo, the model of the knife, the type of steel used and the serial number.











There is also a very rigid stainless steel belt clip. It guarantees an excellent grip on clothes. A hole in it allows you to connect small paracord and laynard carabiners to the knife. If necessary, the clip can be dismantled by unscrewing two small screws.







The blade of the Ruike P843-W comes very sharp, there is no difficulty in cutting both dry and fresh wood.













Following some cutting tests…






















Final Consideration
The Ruike P843-W satisfied me particularly. It is a quality, practical, reliable and usable knife both for EDC and for camping or hiking.

The blade is made of stainless steel, it comes really sharp, cuts very well and seems to keep the line for a long time (this, however, only time will be able to confirm it).

The G10 handle offers excellent grip in all conditions. Its particular processing makes it pleasant and rough to the touch and further improves its grip.


In the hand it is comfortable, well balanced and not tired even if used for a long time.

I really like that there is an auxiliary blade locking system that prevents the knife from accidentally closing.
The materials are of quality, everything is perfectly assembled, there are no "games" or strange movements of the blade.

In short, an interesting product, definitely recommended!
