I only use straight razors, but I prefer the disposables. Way more economical. I use a 1940’s style safety razor most days, the style that accepts a double edged single blade razor. I can get a pack of 20 blades that can last for a couple of months for like $2.50. I think I paid $25 for the handle. They give a WAY better shave than the multi razor cartridges that cost an arm and a leg. They rinse clean easily, and end up with a closer shave with way less irritation and no ingrown hairs.
If there’s time in the morning for a longer shave, I have a Japanese style straight razor that holds half blades. Something like this:
similar quality, and 100 Parker razors for it was $9.99 when I bought it. The handle was $19.99. The blades are so sharp that just the weight of the handle can drag it across a properly lathered beard and cut the hair close enough to feel baby butt smooth. I’ve cut myself a couple of times, but never deep enough to need more than a styptic pencil.
