SwordfishHigh Capacity ‘Curve’ Multiple Size Desktop Manual Pencil Sharpener with Replaceable Helical Blade and Pencil Point Options [40103] 8–12mm

I love this pencil sharpeners. I wish I bought it first off. It takes my bigger pencils like Caran Dache luminance and museum aquarelle like a champ. I still have to test it out with my pastels but I am already satisfied with this.

Lätt att använda och vässar väldigt bra.

One of the best pencil sharpeners I have purchased. Recommend it really good on all pencils.

Ho acquistato questo temperamatite perche' lavoro con matite per lavori artistici (Faber Castell Polychromos, Caran d'Ache Luminance, ecc.) che hanno un diametro piu' spesso rispetto alle matite normali. Oltre a permettere l'affilatura di matite di diversi diametri, da piu' piccoli a piu' grandi, si possono slezionare vari livelli di affilatura della matita, piu' o meno affilata, a seconda dell'uso che se ne deve fare. La lama interna dello strumento puo' essere sostituita una volta che l'affilatura viene a meno. Come tutti gli strumenti Derwent che ho ordinato fin'ora, questo accesssorio e' arrivato ben confezionato, e si presenta come solido e ben curato. Un acquisto che consiglio a chi lavora con materiale d'arte, e non solo.

LOVE THIS! use it for art pencils - charcoal, watercolor, pastel, drawing, standard girth and fat ones like Conte. yes, some pencil tips break - not the sharpener's fault. if a lead is cracked inside the pencil - from dropping it, from rough handling with shipping - ANY sharpener, from a razor blade to a handheld to a fully mechanical - will not be a able to cure a cracked lead. as an artist with arthritic hands, anything that alleviates having to grip something with great strength and dexterity (specifically like sharpening pencils by hand with any razor-based technique or tool) is no longer an option. This swordfish model easily accommodates all the pencil sizes and mediums i use. Based on a very informative youtube video, i use a full width graphite pencil (as in no wood - just a graphite stick with a lacquer coating - does not need to be artist quality - just pure graphite)) about every 10th pencil. According to the well known artist & teacher of said videos, the manufacturer uses graphite as a lubricant. Adjustable to different pencil points with the small knob on the handle - very useful with different mediums and different drawing techniques. i do not aggressively crank down on the pencils. gentle turning and patience yields exactly the results i am looking for.
