They save you a lot of money: Replacement blades cost under $5 for a pack of 10. Each blade lasts for about 5-9 shaves. This is the same frequency you would replace a disposable razor, but each replacement blade is a LOT less than a replacement plastic razor.

Quality: Safety razors give you a closer shave, this also means that you can shave less frequently!

Recyclable Blades: Metal razor blades are endlessly recyclable!

Metal razor blades are endlessly recyclable! Collect blades in a container, then once it is full you can recycle it. Each city had different requirements, in Saint Paul, they can get recycled at scrap metal facilities, not curbside recycling.
