SHARPAL’s Credit Card Knife Sharpener Is the EDC Accessory You Didn’t Know You Were Missing

Posted on by

The most carried EDC is also, statistically, the most neglected one. Pocket knives get used daily and sharpened almost never, because the sharpening step requires a separate tool that most people don’t carry. Bench stones are too large. Pocket rods are awkward. Folding sharpeners add bulk and usually deliver mediocre results on any blade worth maintaining. The gap between “I should sharpen this” and “I have what I need to sharpen this, right now” stays wide for most knife carriers, and a dull edge is the tax they pay for it.

SHARPAL’s answer to that gap is the 113N, a sharpening stone built to credit-card dimensions so it lives wherever your cards live. The stainless steel base measures 3.5 by 2.12 inches and runs just 0.13 inches thick, making it genuinely wallet-compatible rather than merely wallet-adjacent. Industrial monocrystalline diamond abrasive is electroplated across the working face at 325 grit, a coarse cut that restores real edges rather than just polishing ones that don’t need it. A folding ring grip on the back keeps your fingers clear, and a mirror-polished reverse doubles as a signal reflector when the situation calls for it.

Using the 113N in the field is a straightforwardly satisfying experience. The ring grip deploys with a simple fold, slipping over your middle finger and holding the card firmly against your palm while you work the blade across the surface. The contact feels authoritative in a way that smaller pocket sharpeners simply cannot replicate, because the working surface is large enough to take full strokes on a 3 or 4 inch blade without having to reposition mid-pass. The dry sharpening design means no oil, no mess, no preparation ritual, which matters enormously when you’re using it at a campsite, on a trail, or standing over a cutting board somewhere inconvenient. Steel swarf wipes off with a cloth, and the surface stays flat because there’s no hollow ceramic or soft bonded matrix to wear unevenly.

The abrasive choice separates the 113N from the pile of cheap credit-card sharpeners that populate the lower end of this category. Monocrystalline diamond means each abrasive particle is a single uninterrupted crystal structure, harder and more consistent than the polycrystalline alternatives found in bargain products. SHARPAL electroplates those crystals in nickel directly onto the stainless steel substrate, which keeps the surface flat and bonded over repeated use. The 325 grit rating places this firmly in coarse territory, 45 microns per particle, suited to reestablishing a proper edge bevel on a blade that’s gone genuinely dull. For finishing work or touch-ups on a maintained edge, SHARPAL also offers the same card format in 600 grit (114N) and 1200 grit (115N), and the three-pack of all three grits is one of the better value propositions in the entire sharpening category.

That’s just one side of the 113N, on the flip side of the abrasive knife-sharpener is a mirror-finish that has a unique feature. Any polished metal surface can redirect sunlight for emergency signaling, making it incredibly useful in a pinch. Sure, it’s not the primary reason to buy the 113N, but it’s a well-considered detail that fits the ethos of a tool designed to be carried rather than stored. The tan leather pouch included with the card completes the package in a way that feels considered rather than obligatory, protecting the abrasive face and giving the card a home inside a jacket or bag pocket.

The 113N lists for around $10 on Amazon for a single card, or $27 for a 3-pack that includes all three grits. Carrying the 113N alongside a decent folder like the Civivi Elementum or the Vosteed Vombat turns a passive carry into an active one, meaning the blade you grab in a pinch is actually sharp enough to matter. The one thing I’d love to see in a future revision is a dual-grit version with 325 on one face and 600 on the other, eliminating the need to carry two cards for a complete field sharpening session. Until then, the three-pack remains the obvious answer.

Stop Ruining Your Chisels: This Sharpening Kit Locks Angles Every Time

Posted on by

Sharpening often feels like a mini exam you did not study for. Freehand on a stone, trying to hold a perfect angle while your wrists and elbows quietly betray you. Narrow rollers wobble, short blades tip, and edges never quite feel right. The hard part is not abrasion but keeping geometry consistent over dozens of passes, which is why chisels and planes end up less sharp than you want and why knives get retired prematurely.

EdgeForm is a portable precision honing guide that tries to solve the problem at its core by mechanically locking your sharpening angle and stabilizing your stroke. Instead of a one-size-fits-all gadget, it is a modular system built around an all-metal sharpening plate, a wide roller, an angle-measuring plate, and a clamp that holds blades firmly. The goal is to turn sharpening into a repeatable workflow rather than a hand-eye performance that depends on feel and experience.

The main plate has a grooved face for sandpaper strips and a large flat back for full sheets, letting you choose grits for everything from coarse shaping to fine polishing. You cut sandpaper to size, stick it down flat, and get a fresh, predictable surface every time. That means you are not locked into proprietary stones, and you can move through grits quickly without changing machines, just swapping paper and continuing the same motion.

The woodworking workflow uses a precision angle-measuring plate with engraved markings to help you find the right bevel angle for chisels and plane irons. You align the blade with the desired line, attach the clamp, and tighten it to lock the angle. Once clamped, the wide roller rides on the sandpapered plate, keeping the edge at that exact angle as you push and pull, so every pass reinforces the same geometry instead of drifting over time.

EdgeForm includes specialized sharpening boards for small carving tools, allowing both sides of a tiny blade to be sharpened simultaneously while maintaining consistent angles. For other cutting tools, including kitchen knives, you choose the right grit, apply sandpaper to the plate, and sharpen with controlled strokes. A leather strop finishes the process, removing burrs and refining the edge so it feels smooth rather than scratchy in wood, leather, or food.

The extra-wide roller gives a larger contact surface with the stone or plate, preventing side-to-side tipping and unwanted angle drift, especially on short planer blades and narrow chisels where traditional guides often fail. The body is machined from aluminum alloy, with wear- and corrosion-resistant materials and a rigid clamping mechanism that resists slipping and rotation. No electronics, no planned obsolescence, just a mechanical tool built to hold tolerances over years.

EdgeForm is compact and portable, with all components fitting into a small case. It works well on a full shop bench or a kitchen counter in a small apartment. Woodworkers, DIY makers, furniture builders, and hand-tool enthusiasts can use the same system for chisels, planes, carving gouges, and knives, without needing separate jigs or setups for each category, which makes it a realistic daily-carry sharpening kit rather than something that only comes out for special projects.

Instead of dreading a freehand session or accepting edges that never feel quite right, you clamp, set the angle with the measuring plate, roll, and know that the edge you get today will match the one you liked last month. EdgeForm treats sharpening as a workflow problem solved with mechanical precision, not just grit. By making the angles lockable and the process repeatable, it gives you one less thing to worry about and one more reason to keep your edges where they belong.
