Nitram 700306 Abrasive Stone for Charcoal

Nice to have but not a necessity if you can get something cheaper. The quality is good. It looks really nice. It comes with extra pads, too, which you can buy separately if you ran out. Since I hardly do charcoal drawing, this will last me a long time.

Although a bit on the expensive side it is ideally suite for sharpening graphite and carbon pencils as well as charcoal sticks. I keep it on the side and use the charcoal coal powder sparingly to tone my drawings

Works like a charm!

My husband loved it I got it for him at Christmas

This was just what I was looking for. So glad I got it. Love using it for a fine point to my drawing pencils.

They are perfect for sharpening the nitram stick when you need to. You can use cheaper but I can’t see a reason why to give up the convenience of this for a home made solution. Try the nitram sticks they are very cool to work with. To see them in use go to you tube and look it up under nitram and watch Cesar Santos. He has amazing videos to watch using these.

As with all Nitram products top quality. Love their charcoal and this sharpening block is wonderful to use with both willow and compressed charcoal as well as conte.

Decent but its not "abrasive stone" as advertised.Its sand paper stuck on wood. Just buy a pack of sand paper instead for cheaper price and a lot more. (Definitely returning)
