I do a lot of drawing. I have just found a product that helps reduce the stress and pain in my wrists is caused by the back and forth movements required by a standard eraser.

Made by Kohn-i-noor, this battery-operated eraser comes with 2 AA batteries and 8 replacement erasers. While holding it like a pencil, you apply constant pressure on a button to activate the eraser. To stop the eraser, just release the button.

I bought it at Currys Art Supply store.

While it may not last forever, this tool requires a lot less pressure and twisting than an ordinary eraser. I hope others will find this battery operated eraser as useful and pain relieving as I do.
