Interchangeable Parts: Double-edge safety razors

This is the first in a series of posts about cool things with inter­change­able parts. What?

The first time I shaved, I used a cheap dis­pos­able razor that I hap­pened to find in the bath­room. I was 15.

These were dread­ful, by the way.

I did­n’t know any bet­ter at the time, and I did­n’t learn any bet­ter for a while. It was easy to just keep using pro­gres­sive­ly bladier multi-blade car­tridge mod­els. Two blades to start, then four after a cou­ple of years. I stuck with four long after the world had moved ahead, but I soon caught up with the whole five blade deal.

Clear­ly my razor was­n’t the only tool in the bathroom.

I’d hear mum­blings from oth­er men about bet­ter ways to shave, but the thought of my moth­er scold­ing me because I cut my throat open because I was using a dan­ger­ous razor still loomed large in my otherwise-independent adult brain. I was in my mid-20s by that point, but I’ll nev­er out­grow that sort of thing because she’ll nev­er out­grow not let­ting me hear the end of it if some­thing goes wrong.

It’s a good thing I did­n’t lis­ten to hypothetical-her (sor­ry, mom) because if I had, I would­n’t have picked up my first double-edge razor a cou­ple of years ago.

My what?

Double-edge razors are also known as “safe­ty razors” because they were a heck of a lot safer than those big, scary straight razors that were com­mon before them.

It may seem iron­ic today, because it’s def­i­nite­ly eas­i­er to cut your­self with a double-edge than with a car­tridge razor, but you know what else is eas­i­er to cut with a double-edge? The hair on your face. Which is what matters.

Shav­ing with one of these sharp thin­gies requires you to take it slow, but that’s alright.

Seriously though, they’re actually good

I use a double-edge razor because1 I find them to be more effec­tive, lead to less skin irri­ta­tion and few­er ingrown hairs, and over the long run, actu­al­ly be cheap­er. It’s also nice that shav­ing this way leads to a lot less waste to be thrown away.

It was only after I began shav­ing with one for the rea­sons above, that I real­ized anoth­er ben­e­fit: I’m shav­ing with an open sys­tem of inter­change­able parts.

Fuck yeah, interchangeable parts

Since safe­ty razors have been around since the very ear­ly 1900s, any patents on the sys­tem have long-since expired. That means that any­one can cre­ate han­dles or blades that are com­pat­i­ble with every­thing else avail­able for the sys­tem, which leads to a wealth of choice for both han­dles and blades… which of course means low prices.

What excites me much more than the poten­tial for sav­ing mon­ey (sor­ry again, mom) is the poten­tial for cus­tomiza­tion that such an open sys­tem allows. Basi­cal­ly, I can pair any razor designed for this stan­dard—fat han­dles, skin­ny han­dles, short han­dles, shiny onesdouchebag ones, ones from the future, uh, this one—with any blade that I want. This means I can sep­a­rate the style from the sub­stance; I can pair my favorite han­dle with my favorite blade and have what is, to me, the ulti­mate shav­ing machine.

Also, cheap

Ever heard some­one com­plain about how expen­sive it is to shave, or more specif­i­cal­ly, to buy refills for a car­tridge razor? I prob­a­bly don’t need to explain the razor and blades busi­ness mod­el that car­tridge razors fol­low. (If you like pay­ing a lot of mon­ey for the rest of for­ev­er, you’ll love it.)

If you perused those Ama­zon links above, you’re prob­a­bly won­der­ing what’s wrong with my idea of “cheap.” Well, the double-edge razor turns the razor and blades mod­el on its head; in this world, the han­dle is the more expen­sive item, with $30 US not being unusu­al for the more com­mon brands. How­ev­er, this buys a qual­i­ty met­al instru­ment that will like­ly out­live you… and you def­i­nite­ly make up for it with the blades — 10¢ or 20¢ blades are common!

The future

The double-edge shav­ing sys­tem isn’t going anywhere.

While it’s obvi­ous­ly less pop­u­lar now than it was in its hey­day (but so were fedo­ras, and cool guys still wear those), we know how the Inter­net changes things; retail­ers can use it to sell obscure prod­ucts to weirdos every­where, the kind of things mass-market brick-and-mortar loca­tions would nev­er both­er stock­ing on their shelves. I don’t mind buy­ing online and wait­ing a few days, so I can have any blade I want deliv­ered to my door.

Cheap­er, bet­ter and ulti­mate­ly, more inter­change­able. That’s why I shave like this.

An introduction to Interchangeable Parts

I have lots of things in my life. Some of these objects are for fun, some a spend most of their time just tak­ing up space, some are actu­al­ly use­ful, some are a bur­den but must be kept around anyway.

Many of the bet­ter objects in my life share a few com­mon traits. These objects tend to be:

  • less main­stream1
  • more effec­tive
  • more dif­fi­cult to use
  • def­i­nite­ly more customizable

Most impor­tant­ly these items all:

  • fea­ture inter­change­able parts

I’ve recent­ly noticed that I’ve been accept­ing more objects like these — ones that are a part of an open sys­tem — into my life. Why? This was­n’t a con­cert­ed effort but an uncon­scious desire for bet­ter expe­ri­ences… I guess. On a micro-level, each time I chose one of these items, I obvi­ous­ly believed that it would improve a facet of my life that I care about, and do its job bet­ter than its more main­stream, more avail­able, and (pos­si­bly) more con­ve­nient coun­ter­part. I also under­stand why not every­one uses these objects, even though I know their ben­e­fits and find them more effec­tive at their jobs.

So in the com­ing days (weeks, months, what­ev­er) I’m going to be high­light­ing these objects and what they mean to me, how they earned their place in my life, and why I ulti­mate­ly put up with them.

So stay tuned, or what­ev­er you do on the Internet.


  1. Yeah, I know… but it’s true. So not a hip­ster. But isn’t that some­thing a hip­ster would say?[]
