A Gillette illustration from 1905

Gillette started marketing his razors early in the last century. And while it may seem obvious to us today how a three piece safety razor works, he actually had to explain it in his advertisments.

From a 1905 Gillette advertisement

I think that impresses me most – beyond the nicely detailed drawing of a two-ring Old Typerazor – is the absolutely awesome goatee the shaver has.

Towels in Shreds…

Old advertisements can be head scratchers at times.

I mean… who in their right mind wipes their razor off on the good towels in the first place?

A Christmas Razor

Or at least a razor invented by Burton Christmas,1 that is. I’ve touched upon it lightly before, but let us have a more in depth look at it.

As I have repeated time and time again, inventions tends to be aimed at solving a problem. And the problem Mr Christmas tried to solve, was the one of razors being too expensive to make good advertisers – even if Mr Unsinger might disagree. To quote the patent:

William G Frazier’s automatically ignited and extinguished hot water shaving brush

There are times the title of a patents makes me stop and wonder if I actually read what I thought I read. The patent title of “automatically ignited and extinguished hot water shaving brush” by William G Frazier was definitely one of those times. I had to read it more than twice, if I’m to be honest.

How did the old razors shave back then?

A repost for the enjoyment of new readers.

I been thinking again, and sometimes when I do that my brain gets stuck on questions I cant answer…

Given that the original Gillette blade was – among other differences – noticeable thicker and therefore more rigid than today’s blades, and that perceived blade aggressiveness is often linked to blade exposure and angle… would an old razor (like, say, a Gillette Old Type from 1918) shave and feel any different back then compared to these days?

King Gillette’s original patent do state the following:

The blade of my razors made of’ sheet steel having preferably a uniform thickness of about six one-thousandths of an inch.

Or in measures more easy to understand; 6/1000″ = 0.1524 mm.

A fair bit of digging online seems to indicate that modern blades are about 0.10 mm thick, or about 2/3rds as thick as the old blade – assuming, off course, that the original blade was as thick as the patent calls for. It’s hard to tell exactly when blades got thinner, but over on another forum I spotted one guy claiming that

[blades] became a lot thinner after that; I have seen blades from the 50’s and 60’s that went from 0.10 to 0.08 and even 0.06mm.

For all I know the increased thinness of the blades could have started sooner, the the modern shape and perforation of the DE blades seems to have appeared around 1930. Going by the patent numbers listed on a US Gillette Blue from 1935, it’s hard to tell… several references to “thin, flexible blade”, but nothing on just HOW thin it is.

When I raised this question on my favourite shave forum, the guy making my preferred aftershave pointed out that he likes SE razors due to their thicker, stiffer blades – which like DE blades used to be even thicker and therefore even stiffer – since they flexes less. I should probably get my callipers out to measure a new and old SE blade, just to see how pronounced the difference really is.

Stiffening of a blade can also be achieved by twisting it in a slant razor, and slants are often considered to be more “aggressive”… even if I personally don’t think my slants are aggressive, just efficient – perhaps aggressive is the wrong term, even if it’s commonly used to denote the opposite of a mild razor.

Making a number of wild assumptions, desperately pulling on what I learned in structural mechanics more than two decades ago, and hoping that this website have got their code right; the old blade ought to be twice as stiff as the current blades – with the biggest caveat being that the modulus of elasticity is the same for the steels used.

These guys offers three hole blades that are a dimensional match for the pre-1929 Gillette blade… and it seems that one of the thickness’s they offer match the old blades. But the blades are made for cutting plastic film, so they will probably be rotten for shaving with.

After all that searching and math, I still have no real idea how a blade twice as stiff would affect the behaviour of an Old Style Gillette… Combining what what we know about SE razors and their stiffer blades with what we know about the torsionally stiffened blades in slants, I’m leaning towards the idea that the Old Type Gillettes using the pre-1929 blades may have been more aggressive than they are with the thinner blades of today.

I may be wrong though, with all the assumptions and guestimates underpinning that idea.

Walled gardens, and how they apply to shaving

A repost from five years ago for the enjoyment of new readers

A lot of modern shave gear can be seen as part of a walled garden; a term most often used around computers that describe a closed platform where a single entity (provider) has control over applications, content, and media, and restricts convenient access to non-approved applications or content.

The many, many razor blades of John Holtzman

In the early 30’s, the patent for the Gillette three hole blade was about to expire. This inspired Gillette, Gaisman, and others to come up with blades that could both be used in the old Old Type razors and also a new razor that would not accept the old Gillette blades. As we know now the Probak won, but for a while it was open for everyone to try. And one of the ones who tried was John Holzman.

Japanese barbers, ca 1866

Possible one of the earliest photos of Japanese barbers.

Early photo – taken on albumen silver plate and hand coloured – by Felice Beato (1832-1909), an Italian-British photographer who were one of the first to take photos in East Asia.
