Excellent

### ⭐⭐⭐⭐ Small but effective.
*by P***E on 27 April 2019*

I thought the price for this brand was roo good to be true. These are small. Just, and I mean just big enough for most chisel, but plane blades will need something larger. These do sharpen enough to cut hairs off the back of your hand. Perfect for pen knives. I'll have to save my pennies for the larger ones.
