Yes they do after you ream a dozen or so APC props. Those props have fiberglass in it and it's very abrasive to cheap and easy to machine 4140 heat-treatable steel (non- M-2 or drill blank) which the prop reamer is most likely made of. If you know what you are doing and have good hands, you can give them a new edge a few times with a dremel /cutting wheel or a diamond hand hone.

When using a prop reamer, hold the tool stationary, turn the prop and always start from the back or engine side.
