SRM7228BMN2: 7228B-MN2 Large Rubik Folding Knife - Brown Micarta

SRM Knives

Named after the Cube of the same name, the 7228 Large Rubik folding knife was designed to emphasize the same fun experience while using it. This large version of the folder has the same wide blade, perfect for everyday tasks at home or at the campsite with an over 3" size. Crafted with laminated 140Cr steel, the blade boasts performance comparable to S35VN, offering an excellent balance of toughness, edge retention, and corrosion resistance. The cooled sharpening process maintains the blade’s hardness for a sharper, longer-lasting edge, while the anti-loosening pivot system ensures stability and smooth operation through rugged use. The Micarta handles give a firm and comfortable grip that looks sleek and modern. The ambi-lock and reversible pocket clip make this knife truly ambidextrous for any user. A high-quality pocket folding knife, the Rubik 7228 series, is built to enhance your outdoor life or EDC life by feeling comfortable, easy, warm, and bright.

Pros: Blade Material, Blade Sharpness, Ease of Opening, Handle Feel, Handle Material, Lock Ease of Use, Lock Type, Overall Quality, Pocket Clip, Sheath, Weight
Cons: None
Excellent Quality for Price. Especially if Advertised HRC is Correct.
Blade came very sharp with a pretty clean edge, has no lock stick, nice action that drops shut, and deploys smooth. Ergonomics are nice, no sharp corners or obtuse angles, I can get a nice four finger grip and choke up near the blade if needed. Micarta has a comfortable feel, it is a bit darker than the display picture (more of a brownish orange). Probably the BEST feature of this knife is how light it is for its size and construction. The proposed HRC is 61-63 which I'm hoping is correct, if so, those are amazing numbers for this price.The ONLY cons I can give this knife is the pocket clip. Due to the way it sits in the bottom notches, it just has a little bit of side to side play, but its quite negligible. The other con being: I wish the fuller that it has was a bit more exposed to allow a reverse flick deployment. But again its not too big of an issue.
