CANOPUS Single Edge Industrial Razor Blades - 10 Pack USA-Made Safety Straight Edge Razor Blades for Box Cutting, Carton Opening, Glass Scraping & Paint Removal | Durable Replacement Blades for Industrial & Home Use

I purchased these razor blades for scraping accumulated grease, etc. from an rv's leveling jacks. Wasn't certain that a razor blade was the correct "tool" to use, but it worked great. These are quite sturdy, uniformly sharp, and could be used for many applications. They're packaged in a plastic bag, with cardboard covers for the blades; for the price I didn't expect a container; they can easily be stored in a small jar or medicine bottle. Being made in the USA is a bonus for me.
