The SRM Rubik 7228B-ME2 is a tough, full-size everyday carry knife built for hard use, emergency tasks, and outdoor reliability. Designed as a practical tactical folder, the Rubik delivers strength, smooth action, and ambidextrous control in a durable Micarta platform.
Its 3.43-inch drop point blade is crafted from laminated 140Cr steel, combining a hard core with stainless outer layers for improved toughness, corrosion resistance, and edge stability—performance comparable to premium EDC steels. The bead blast finish reduces glare and hides wear while keeping the knife work-ready.
The Micarta handle provides excellent grip in wet or dry conditions and offers a warm, natural feel in hand. Inside, the mono-chassis liner reinforces strength and lock stability without adding unnecessary bulk.
Deployment is fast and smooth thanks to the thumb stud and ceramic ball bearing pivot. The Ambi Lock (crossbar lock) delivers secure lockup and easy one-hand closing, fully usable for both right- and left-handed users. A reversible ambidextrous pocket clip ensures flexible carry options.
From cutting cordage and prepping camp to daily package duty or emergency use, the Rubik is built to handle real-world tasks with confidence.
