I actually still have my old Schick safety razer that takes injectable blades, but if I needed another, I'm not sure I could find one. I have been buying blades for it on Amazon because the local stores no longer carry them.

Links to the blades:

This would be a similar razer:

These kinds of old school razers are getting hard to find. They last forever and you just have to buy blades.

Newer plastic razers with multiple blades are complete garbage in comparison. My old Schick razer will give me multiple shaves with a single blade. It will cut through a weeks worth of stubble like it's nothing. These newer throw away razers with multiple blades will clog and become useless in one swipe if you have any stubble at all.

It's obvious that the old school razers were built to last, while newer razers are built to be thrown away and replaced.
