Yeah, but you can buy a box of 100 DE blades for, like, $15. (Seriously: see https://www.westcoastshaving.com/collections/bulk-de-safety-...) So even if you change the blade every other shave, it still comes out cheaper.

This is a benefit of standardization: DE blades all have a common form factor, so any handle can use any blade. That means every DE blade maker is competing with all the others, which drives prices down. Cartridges on the other hand are all proprietary to the vendor that made the handle they fit with, so there's much less downward pressure on the pricing.

> if that isn't a strong indictment of saving pennies, I don't know what is.

The thing about a DE blade versus a cartridge is that with a DE the range of possible outcomes is much wider than it is with a cartridge. A DE blade can produce shaves ranging from "ow, I cut myself!" to "smooth as a baby's bottom", depending on the technique you apply to it. A cartridge won't ever cut you, but it'll also never give you as close a shave as you can get with a well-wielded DE blade; it provides a consistently mediocre shave every time.

To put this in terms HN readers will appreciate, arguments about DE versus cartridge tend to be kind of like arguments about vim/emacs versus IDEs. Vim and emacs users love to talk about all the crazy things they can do with their editor that no IDE can match, but they rarely talk about the learning curve they had to climb to reach that level of technique. Whereas IDEs tend to be less elegant, but by hewing more closely to modern desktop interface standards they let their users reach an acceptable level of productivity faster. Those IDE users will never reach the heights of wizardry that are possible with vim or emacs, but since very few programmers are true wizards anyway that doesn't really matter much to everyone else. Like the cartridge razor, the IDE is "good enough."

I don't for a minute believe that cartridge razors are incapable of giving me equally good shaves.

99% of the benefits of DE and straights is the incredible care you have to take with your technique, the awareness you need of your face's contours, and the grain of your beard over in multiple passes.

People who stick with wet-shaving care a lot about getting all of that right, and do a lot of work to get there. Similar attention to those things while using a cartridge will get you similar results. At least in my experience.

I wet-shave because it is more environmentally friendly, and I love the ritual. Also, it is cheaper.

I've been surprised in this thread about people talking about taking incredible care. It came very naturally to me. I was put off using DEs for decades because I thought they were hard to use and dreaded cutting myself. Now I'm sad I never used them before.

I would do a very poor job compared to all the knowledge there.

I feel like that some people (myself included at times) just like to develop skills with a steep learning curve regardless of how much benefit it actually incurs.

No, it's not. If anything there is a belief that DE blades actually stay sharp and last longer than cartridge blades. I don't know if there's any evidence to that, but the effect is that many DE shavers keep their blades for a number of shaves. I suspect that some are more inclined to swap blades frequently because the blades are so (comparatively) cheap.

I’m not sure how much you could reuse a single blade. Of course I think it was like $25 for 100.

For comparison, I’ve also used a Mach 3 blade for a month, so the Mach 3 blades lasted longer than a single blade but cost much more $40 for 10.

I find this hard to believe. I can use a single Gillette Fusion 5 cartridge for a month or more.

For me, the most noticeable difference is my daughter would never use my DE safety razor on her legs. The cartridge style.. well.. they dulled out way faster than they should have from my usage.

A $30 Wahl Peanut with a few guides, and 5-10 less minutes wasted in the morning per trim... and you get a beard!

Not everyone can grow a full beard.

I’ve had it since 2016. I mostly use it for shaving my head.

I develop dandruff under facial hair, just like the top of my head.

1. Regular hot water on your hair and beard dries out your skin terribly. Especially during winter. You need to use luke warm showers and probably avoid washing your head every time you shower. Use cold water on your face afterwards and gently dry it off. Which leads into the other point.

2. Stop touching your face so much. Routinely or obsessively touching your face or beard irritates it a lot. That can inflame the skin, causing it to over produce skin, oil, etc.

Also using too much beard oil as well can cause irritation. Your skin doesn't need too much oil. Only what it produces naturally (when you don't wash it away with soap or hot water).

For me, after learning with a shavette straight razor, the DE is easy mode for when I have no time.

The majority of that comes from the handle, not the blades. You can buy 100/500 pack of blades for dirt cheap
