My tactical pocket knife has gone dull—what’s the quickest 4-step way to get it razor-sharp again?

1. Clean the blade with a soft cloth to remove oil, dirt, or debris. 2. Soak your double-sided whetstone and set it on a non-slip surface, coarse side up. 3. Hold the EDC knife at a steady 15° angle and push the edge evenly from heel to tip 10–20 times; flip and repeat on the other side. 4. Turn the stone to the fine side for a quick polish, using the same gentle motion to restore a hair-popping edge.

SRM EDC knife – Quick Use & Care Points

1. Use: Only for cutting tasks; no prying, twisting, or hammering. 2. Clean: Allow to dry completely after each cleaning to avoid moisture. 3. Lube: Oil your EDC knife after each use or weekly; a drop of lubricant on the pivot and blade will prevent rust. 4. Rust: Polish away spots with semi-chrome metal polish if needed. 5. Tighten: Check screws monthly with T6/T8 Torx and add a touch of removable thread-locker.

Meet the SRM Rubik: Premium tactical pocket knife.

The SRM Rubik is your go-to tactical pocket knife—slice through seatbelts in emergencies, bust open stubborn packages, or prep campfire kindling outdoors. And opening letters, trimming frayed threads off your gear, or even prepping lunch on a hike. It’s that versatile.
The Rubik features an ambidextrous lock (crossbar lock) and ambidextrous pocket clip, making it easier to switch pocket positions and use. A variety of sturdy handles (G10, Micarta, and aluminum) provide a secure grip. The standard Mono chassis liner makes the handle more sturdy and is a highlight of the Rubik. The tough, corrosion-resistant drop-point blade offers rugged, reliable protection, no matter where you're headed (or on a mission). The Rubik collection utilizes a thumb stud opening method, which facilitates faster and smoother opening of the knife.
All in all, the Rubik is not only a tactical EDC knife, but it is also an outdoor and camping knife suitable for everyday carry! Get one for yourself！
