The Cold Steel Double Sided Knife Sharpener – Black Folding Diamond Sharpener, Coarse/Fine (Model CSKSDSDW, UPC 888151038215) is a rugged, pocket-friendly sharpening tool designed for anyone who wants fast, reliable edge maintenance in the field, the shop, or at home. With coarse and fine diamond plates built into a folding “pocket knife style” handle, this sharpener gives you a complete two-stage sharpening system that fits easily in your pocket, range bag, tackle box, or tool kit.
Dual Grit: Coarse & Fine Diamond in One Compact Tool
The CSKSDSDW features two diamond-coated sharpening surfaces so you can repair and refine edges with a single tool:
Diamond abrasives cut aggressively and stay flat, making them excellent for modern steels and hard-use blades that can overwhelm traditional stones.
Folding “Pocket Knife” Style for Safe, Easy Carry
The Cold Steel Double Sided Sharpener is built like a folding knife:
Sharpening plates fold into the handle, protecting the diamond surface and your gear
Compact, slip-in-pocket design that’s easy to carry in jeans, packs, or tool bags
Keeps grit and debris off your other gear while preventing accidental scraping or scratching
When folded open, the plates lock into a straight, comfortable configuration that feels natural in the hand for controlled sharpening passes.
Black Handle with Secure Grip
The black handle is designed for both durability and control:
Textured or contoured grip area for better hold, even with wet or gloved hands
Rugged construction to withstand drops, field use, and shop environments
Low-profile black finish that pairs well with other knives and EDC gear
You get a sharpener that’s tough enough for outdoor use, but refined enough for a workbench or kitchen drawer.
Versatile for Knives, Tools, and Outdoor Gear
This folding diamond sharpener is not just for pocket knives:
Great for EDC folders and fixed blades
Sharpens hunting and fishing knives, including gut hooks (using the corner/edge of the plate)
Useful on multi-tool blades, small axes, hatchets, and some serrations (very carefully, on the edges)
Handy for shop utility knives, box cutters, and craft blades
If it has an edge and you can safely hold it, this double-sided diamond plate can probably bring it back to life.
Ideal for Field, Range, Shop, or Kitchen Use
Because it’s portable and tough, the CSKSDSDW fits naturally into many setups:
Hunters & outdoorsmen – Keep it in your pack for quick touch-ups while dressing game or processing wood.
Fishermen – Keep hooks and fillet knives sharp on the water.
Range & tactical shooters – Maintain field knives and utility blades in range bags.
Home & shop users – Toss it in a drawer or toolbox for fast edge work on everyday cutters.
Instead of waiting to sharpen at home with bulky stones, you can maintain your edge on-site, minimizing downtime and keeping blades safer and more effective.
Simple, Effective Sharpening in a Few Strokes
Using the Cold Steel Double Sided Knife Sharpener is straightforward:
Open the sharpener fully so the plates form a straight line.
Start with the coarse side for dull or damaged edges, maintaining your preferred angle (commonly 15°–20° per side for many knives).
Draw the blade along the plate, alternating sides, until a consistent edge is formed.
Flip to the fine side and repeat with lighter strokes to polish and refine.
Wipe the blade clean and you’re ready to go.
Diamond plates work best with light pressure—let the abrasive do the work for smoother, more controlled results.
Low-Maintenance Diamond Abrasive
Unlike traditional water stones or oil stones, diamond plates are easy to care for:
No soaking or oil required—use dry or with a little water if desired
A quick wipe or rinse removes metal swarf and debris
Long-lasting abrasive surface that stays flat over time
That means less hassle and more time with a sharp, ready-to-work blade.
