Product overview
Bristle pencils are retractable abrasive tools shaped like a mechanical pencil. Twist the barrel to extend or retract the bristle bundle — the shorter you set the bristles, the stiffer and more aggressive the abrading action. Extend them further for a softer, gentler touch. One tool, adjustable intensity.
AK Interactive's range covers five bristle materials, from gentle nylon to aggressive steel, so you can match the tool to the task: delicate cleaning, paint removal, rust scrubbing, surface keying, or controlled weathering effects like chipping, scratches, and wear marks.
For miniature painters and wargamers, these are a secret weapon for realistic weathering. Instead of painting on scratch effects, you physically create them — real micro-abrasions on the actual model surface that catch light and look convincing from any angle.

The softest option — ideal for beginners who want to experiment without risking detail damage. Gentle, controlled micro-abrasions for subtle surface texture and light weathering.
Best for: Light cleaning, gentle derusting, subtle scratch texture on armour and ruins, cleaning tools, texturing XPS foam and soft plastic.
The step up from standard nylon — a bridge between soft nylons and metal bristle types. Visible scratches and wear marks on plastic and resin without gouging deep grooves.
Best for: Edge weathering on vehicles and mechs, scraping back pigments for chipping, concrete/asphalt texture on 25–40 mm bases. The workhorse for wargaming weathering.
The sweet spot between abrasive power and surface safety. Cleans and abrades effectively without the risk of deep scoring that steel can produce.
Best for: Cleaning metal parts, removing oxidation and tarnish, keying surfaces before painting, medium-intensity weathering scratches on vehicles, terrain, and large bases.
Fine glass fibre filaments for controlled matting and micro-cleaning. Creates a very even, uniform scratch pattern — excellent for breaking gloss finishes and prepping photo-etch.
Best for: Derusting, removing burrs, matting glossy surfaces before washes/decals, subtle paint wear on armour panels, prepping PE for adhesion.
⚠ Fiberglass dust is a skin and lung irritant. Avoid touching the tip. Work over a wipeable surface and consider a dust mask for extended use.
The most aggressive option — hardened steel bristles for maximum cutting power. Fast, deep material removal for when you need results quickly and aren't worried about subtlety.
Best for: Aggressive cleaning of metal parts, deep battle scratches, heavy chipping and gouged-metal effects, fast rust removal, stripping stubborn dried paint.
All five pencils share the same twist-barrel design. Rotate the end cap to adjust bristle length:
👉 Short extension = stiffer, more aggressive. Less flex means more force transferred directly to the surface. For heavy cleaning, deep scratches, and fast material removal.
👉 Long extension = softer, gentler. More flex absorbs pressure, giving a lighter touch. For delicate cleaning, subtle weathering, and fragile surfaces.
👉 Combine bristle type + extension length for a wide range of effects. A steel pencil on long extension can be surprisingly gentle; a nylon on short extension can be surprisingly bitey.

👉 Start gentle, escalate if needed. Begin with nylon and work your way up. You can always add more abrasion — you can't undo deep scratches.
👉 Use directional strokes for realistic scratches. Work in the direction wear would naturally occur — along edges, around handles, across flat panels where gear would scrape.
👉 Combine with washes and pigments. Create physical scratches, then apply a dark wash over the area. The wash settles into real scratches, creating effects that painted-on weathering can't match.
👉 Brass for metal minis, nylon for plastic. Use brass or steel on metal parts for aggressive results, and nylon/hard nylon on plastic and resin for control without gouging.

⚠ Bristles are consumable. Like sandpaper, they wear down with use. Steel and brass last longest; fiberglass and nylon wear faster. The pencil body is not refillable.
⚠ Test on a hidden area first. Especially with brass, fiberglass, and steel — try on an inconspicuous part of the model before working on a visible surface.
⚠ Fiberglass safety. The AK9542 sheds micro-particles that can irritate skin and lungs. Don't touch the bristle tip with bare fingers, avoid breathing near the work area, and wipe down your desk afterwards.
Notes · Q & A
Which magnet size should I choose for miniatures?
A 2×1 mm disc suits infantry weapon swaps, while 3×1 mm is a practical step up for arms and small components. Sizes around 3×2 to 5×2 mm work well for basing and larger parts, with 5×3 mm and above better suited to vehicles, large models and army transport. Each listing includes a calculated pull figure in grams so you can compare sizes on the same basis.
What does the N42 magnet grade mean?
The grade describes the magnetic material: at identical dimensions, a higher number generally produces more pull. N52 is typically around 20–25% stronger than N42 at the same size, but increasing the magnet's diameter or thickness usually makes a larger practical difference than changing grade alone. Our range is clearly specified as N42.
How do I keep the polarity consistent?
Before separating the stack, mark one face with a permanent marker and use that mark as your polarity reference. Dry-fit every pair before applying adhesive, and glue the two halves while the magnets are still attracting each other in the intended orientation. Reversing one magnet is one of the most common magnetisation mistakes.
What size hole should I drill for a magnet?
Use a drill matching the magnet diameter; for a designed 3D-printed socket, allow roughly 0.1 mm extra diameter. Make the recess approximately the magnet thickness plus 0.2 mm for adhesive so the face can sit level with the surrounding surface. CA adhesive is suitable for fixing these magnets into plastic, resin or metal parts.
How should neodymium magnets be handled safely?
Swallowing two or more magnets can cause serious internal injury, so keep loose magnets away from children and use them only for adult hobby work. Neodymium magnets are also brittle and may chip if allowed to snap together. Bring them together slowly from the edge rather than letting their flat faces strike each other.
