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 (or at least offered) 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.
From time to time we’re hearing that the dedicated forum – be it for shaving, computers, woodworking, or any other hobby or interest you might care to mention – is dead, pushing up the daisies, kicked the bucket, shuffled off its mortal coil, run down the curtain and joined the bleeding choir invisible. Killed by groups on Facebook and Reddit, if the reports are to be believed.
It’s easy to blame “social media” for the alleged decline in the activity on dedicated forums… except that a forum is also a social media, so finger pointing in that direction don’t really work. Onion in my belt, get of my lawn etc… I can recall when Yahoo Groups was the hot place to hang out, so that kind of dates me when it comes to social media and online interactions.
Facebook, Reddit and the like have both lowered the bar and (over)filled peoples time and attention – but the fact that the dedicated shave forums are still here speaks volumes; they offer not just an interest based camaraderie but also a deep well of knowledge that’s hard to beat. In addition each board have a certain, how to put, feel to it as a venue… there is no doubt in my mind that people interact differently on places like Facebook and Reddit than they do on a traditional forum, and there is big differences between the various forums as well. To me at least it’s more participation on a forum than on what most people think about when they say “social media” – to me the later seems to be more about telling people what you do, rather than about listening to what they do.
But ignoring all that; the traditional shaving forums is still a community of friends first and foremost, and while people come and go it’s always great to have a friend come back to the forums.
So welcome back to the forums if you havn’t hung out there for a while – and if you haven’t hung out at all perhaps you should come over and see what they offer that Facebook and Reddit does not.
