Professional quality for home use
I bought this for my architecture sketching kit. It handles my large charcoal pencils and regular graphite pencils with equal precision. The shavings container is easy to empty.

Worth every penny
Expensive compared to basic sharpeners, but the durability and consistency make it worth it. It has been in daily use in our classroom for three months with no issues.

Great sharpener, slightly bulky
It works exactly as advertised. The dual-hole system is convenient so you don't have to swap inserts. It is a bit larger than expected, but that adds to its stability on the desk.

Good but requires firm mounting
The sharpening action is smooth, but if you don't hold it down firmly or mount it to the wall, it tends to slide around on the table when cranking thick jumbo pencils.

Perfect for our homeschool art station
This sharpener is a game changer. We use both standard and jumbo pencils for drawing, and this handles both effortlessly. The build quality feels very sturdy, typical of Austrian engineering.

No more broken tips!
My kids used to break pencil tips constantly with our old wedge sharpener. This rotary mechanism creates a perfect point every time without breaking the lead. Highly recommend for young artists.
Q: Can left-handed people use this easily?
A: Absolutely. The crank handle can be positioned on either the left or right side of the unit, making it fully ambidextrous.
Q: Does it come with screws for wall mounting?
A: Yes, the package includes two screws and anchors suitable for mounting the unit securely to a wall or vertical surface.
Q: What is the maximum diameter for the jumbo hole?
A: The jumbo hole accommodates pencils with a diameter of up to 12mm, which covers most oversized drawing and coloring pencils.
Q: Can this sharpener handle colored pencils as well as graphite?
A: Yes, the Carbo Jumbo is designed to sharpen both graphite and colored pencils, provided they fit within the standard or jumbo diameter ranges.
Q: Is the blade replaceable if it gets dull?
A: The blade is made of high-quality hardened steel and is designed for long-term use. While technically replaceable by a professional, Cretacolor recommends contacting support for blade services rather than attempting self-replacement.
