The Amazon Basics Men’s Single Edge Razor Blades are a great set of disposable razor blades that are sharp and perfect for using your various devices. While I don’t use razor blades for shaving purposes, I do use them in a very specific tool – a balloon cutter. The blades fit in my cutter perfectly, stay sharp despite repeated use, and they seem to last much longer than the more expensive blades I’ve purchased at my local drugstore. The blades are packaged well so you won’t accidentally cut yourself and they’re all uniformly shaped and sharpened. Overall, they’re great blades that I will purchase again once I eventually run out.
