Review on M&R Replacement Blade Sharpener - 10/Box by Kelsey Brown

UPDATE: O1-08-2018 worked well with a small aluminum sharpener and I was finally able to get the old blades out of an Alvin brass round-hole sharpener. they work very well - while new. but I don't think they stay that sharp for long. The copper sharpener was accidentally dipped into a stainless steel container that contained old stainless steel forks and spoons, some old bowls and dish soap. etc. Today after a few months of this mix all sitting together - it was accidentally hidden - this is what the blades looked like. The sharpener was fine, a little stained, but I was SO surprised at the corrosion on the blades. target, that steel corrodes? Maybe the quality isn't good enough to stay sharp. I only use colored pencils and sometimes I sharpen a graphite pencil. so I change blades more often than I would like.
