Used extensively throughout Physics, and it was quite handy for the constant re-do's of problems. I hate pencil, pretty much do all my work in pen, but this eraser actually completely removes any trace of the pencil. The knock design can recede every so often, but it wasn't excessive or annoying.

I use this all the time for school and it's a really good eraser, but it leaves a lot more eraser dust than other dust gathering erasers I've used before.

Excellent knock eraser. Wide enough for larger erasing, and narrow enough for some detail work. I use this while completing my engineering homework which can be detailed and long and I hate recopying it. Works well with heavier marks and I tried it with success on a grade H lead. Does have dust gathering properties.

I have a lot of erasers, and if I am erasing less than half a page this is my go to choice.

Best and most practical eraser I've ever used. Excellent for musical composition or proof-writing for math. Erases very cleanly.

Downside is that it produces a lot of dust (although they do clump together), so I burn through this eraser much faster than any other. Still totally worth it, would get again.
