Nitram 700306 Abrasive Stone for Charcoal

Using Nitram is lovely for portraiture as it gives a soft, less obvious 'charcoal' feel to a picture. The sharpening bloc allows you to save the charcoal dust for using as charcoal dust on images or for backgrounds.

As a tool, it's very practical. Is it worth £10? Maybe not.While I swallowed the bullet and paid £10.70 for my first one, I hesitantly thought I could buy a spare one for travel. But over night...boom!! the price nearly doubled!! So, no, thank you! I refuse to be exploited. Thanks for profiteering from Covid-19, Amazon!!So I made my own and it cost me zero money. It works as effectively and it looks nice. I even stopped using the Nitram stone now.That said, the Nitram piece is very good and I don't think you'll ever use normal sanding paper having used this one. It provides a generous surface for sanding charcoals (especially Nitram ones) and lasts for a long time. It comes with two spare sanding pieces, as well. The surface may be too rough for graphite, though.

Works well

Dry happy with the sharpening block, works a treat giving room and with a little care wow never seen charcoal with a point like this. 11/10

grate for charcoal

very good

Good quality tool

Works like a charm!

C’est un bon produit, de bonne fabrication. Il est livré avec des surfaces abrasives de rechange. Permet de récupérer et réutiliser la poudre de charbon taillé dessus. Bref, c’est le genre de produit dont il est difficile de regretter l’achat.

Worksreally well, I currenntly use nitram charcoal so. I can't state whether its as good with charcoal from other brands yet. 2 extra blacksandstone patches are included in the package.

Great tool for sharpening pastel pencils, most of which don't fit conventional and automatic sharpeners.

削りこごちが、とてもいいです。カバーの厚紙は、マジックテープがついてるので、使い回せるので、それも気に入っています。
