Sharpening colored pencils is best done by holding the pencil still and turning the sharpener gently to avoid snapping the softer wax core.
Unlike graphite pencils, colored pencils have a delicate wax or oil-based core that snaps, crumbles, and tears easily under pressure. The most common way people ruin their pencils isn’t the blade—it’s the technique. A light touch and the right motion keep the point sharp and the core intact.
The Two Golden Rules For A Clean Point
Most breakage happens because of how the pencil moves through the blade, not because of the pencil itself. Two simple changes eliminate most problems.
- Turn the sharpener, not the pencil. Grip the colored pencil firmly in one hand and rotate the sharpener around it. Twisting the pencil puts uneven strain on the core and increases the chance of a snap.
- Use a gentle touch. Let the blade do the cutting. Pressing hard to “hurry up” the point is the #1 cause of broken tips and shredded wood.
If you’re using a handheld sharpener, these two rules alone handle most of the work. Take the pencil out the moment you feel resistance drop—a telltale sign it’s done.
Choosing The Right Sharpener For The Job
Not all sharpeners handle colored pencils well. A standard graphite sharpener often has blades that grab and tear the softer wax core instead of slicing it cleanly.
The broader takeaway: match the sharpener’s opening size to the pencil’s barrel. A loose fit lets the pencil wobble, which strains the core. A snug fit keeps things stable.
What To Do When A Colored Pencil Won’t Sharpen
Every colored pencil user hits this wall eventually. The pencil goes in, but all you get back is dust and a broken tip.
- Check the blade. Dull blades cause tearing, rough points, and more breakage. If the sharpener is struggling, its blade is likely past its prime.
- Clean the blade. Wax from colored pencils builds up on the cutting edge over time.
- Give soft pencils more room. Softer, wax-based cores are more fragile than harder ones. If a pencil keeps breaking, try a sharpener with a larger opening or a sharper blade—the extra space reduces strain on the delicate core.
If you’re still fighting the pencil, consider sharpening by hand instead.
Sharpening With A Knife Or Sandpaper
A knife gives you total control over the point—useful for soft, fragile cores that snap in mechanical sharpeners. The tradeoff is risk. Keep the blade directed away from your body and shave in small, careful passes, rotating the pencil as you go. Work slowly; a slip with a knife is serious.
Sandpaper is a finishing tool, not a primary one. After you have a basic point from any method, a few light swipes on fine-grit sandpaper shape and smooth the tip into a precise point without the pressure that breaks cores. It’s also the go-to fix for a point that’s sharp but rough.
Whichever method you pick, the principle stays the same: steady pencil, gentle movement, and clean cutting tools.

FAQs
Why do my colored pencils keep breaking in the sharpener?
Soft, wax-based cores snap when they hit too much pressure or a dull blade. Rotating the sharpener around a still pencil instead of twisting the pencil itself, plus cleaning wax buildup off the blade, resolves most breakage.
Can I use a regular pencil sharpener for colored pencils?
Yes, but standard sharpeners often have blades that grab and tear softer cores. Sharpeners designed for colored pencils, like Prismacolor’s Premier and Scholar models, use blades tuned to slice wax cores cleanly and are worth the switch if you sharpen often.
Is knife sharpening better than a mechanical sharpener?
Knife sharpening gives you maximum control over the point and is ideal for very soft cores. It also carries a cut risk and takes practice. For most people, a good mechanical sharpener with a clean, sharp blade is safer and faster.
