Pros: Effectiveness, Overall Quality, Ease of Use
Cons: Durability
Smaller than expected but works really well
Ok, this won't work magic but it will do a good job of cleaning up stains, stubborn gunk, light corrosion. When you own non-stainless knives you know how some just seem to rust when you turn your back or you neglected your knife a bit. Also nice to clean up with after sharpening. It's a spongy material, like a less dense pencil eraser. For the price it's worth a try on stubborn gunk and on the D2 blade I swore I cleaned before putting away but nope. Being a bit on the smaller size is a benefit for getting into smaller crevices or closer to the handle, choil, differently finished portions of the blade. I wish they made a sharpening stone size too but this is worth the $
