Barber paradox

The barber paradox is a bit of mental gymnastic derived from Russel’s paradox, that shows that an apparently plausible scenario is allegedly logically impossible:

Suppose there is a town with just one barber, who is male. In this town, every man keeps himself clean-shaven, and he does so by doing exactly one of two things:

  1. shaving himself; or
  1. being shaved by the barber.

Also, “The barber is a man in town who shaves all those, and only those, men in town who do not shave themselves.”

Starting from this, one is supposed to ask the question “Who shaves the barber?”, which allegedly leads to the paradox…

In this day and age the solution ought to be simple though; the barber is logically a woman*. Simple as that!

*) At least in Norwegian that is – the term “a man” is often used (correctly or incorrectly) as a somewhat genter neutral way of saying “a person”.

Inside the weird world of disposable cartridge razors

I found an interesting piece of journalism from last year while bouncing around the internet a little while ago, and wanted to share it. It is about the 34 billion(!) world of disposable razors, and the shenanigans the large and small players gets up to in order to get a larger piece of the cake.

Some interesting nibbles:

  • Gillette’s Fusion ProGlide Power Razor consists of more than 60 parts, while several of my razors consists of just three parts.
  • The journalist point out there is an increasing market for traditional safety razors and straights, and this leaves the big players in a conundrum; “They can’t say, ‘Actually, you don’t need five blades, you just need one really sharp one.’.”.
  • The M3 Power was “proven” in court to shave closer than “any other blade on the market” (implied to be carts) – by a whooping 0.0143mm (a little over 5/10000″)…
  • Simple lack of space means seven and eight blade carts are unlikely to happen. But the manufacturers have off course tried for six and seven blades…
  • There are 20,000 patents active in the razor market, and who knows how many that has expired.
  • Shaving your body is – apparently – the latest fad and the height of fashion for guys. Who knew?

A minor niggle: The journalist claims that the safety razor is “a prosaic piece of plastic designed to be thrown in the bin as soon as its short life is over.”. My selection of metal DE’s and SE’s beg to differ – a couple of them are centenarians by now.

More advice for the Gentleman

Traditional wetshaving is a gentleman’s hobby…

… so I’ve given a bit of though as to what makes a man into a gentleman. There is many rules, guidelines and opinions to this, as well as at least one tumblr-blog devoted to the subject.

I really liked these though:

Prepwork looks okay and the razor is plenty sharp, but he really needs to work on the angle…

Or at least for the marketing effort…

Old Time Advice: Care of the face after shaving

Shaving made easy is a book from 1904 that I have mentioned before on my blog.. it’s an interesting read and it’s free (as in beer), so why not download it and give it a read? Even if it’s 111 years since the book was printed, the advice given is just as valid.

CARE OF THE FACE AFTER SHAVING.
Most men who shave themselves seem to think that when they have removed the beard, they have nothing further to do. This is a great mistake. They undervalue the importance of a proper treatment of the face. A quick and easy way of caring for the face after shaving, is to remove the lather by a thorough washing, then to apply either witch hazel, bay rum or some other good face lotion, and to follow this with a small quantity of talcum powder, evenly applied. This is probably about all that the average man will usually find time to do.
In order, however, to keep the skin in a healthful condition, a little more elaborate treatment should occasionally be given. We recommend the following: Wash the face thoroughly to free it from the lather, and then apply a steaming hot towel, as hot as can be borne. The heat and moisture draw the blood to the face, open the pores, and set up a healthful action of the skin. Next apply witch hazel, and finally give the face a thorough massage. There is no other treatment so beneficial to the skin. With many persons the flow of blood to the face and scalp is very sluggish, because of enfeebled or slow heart action; and in consequence, the many small arteries and capillaries become clogged. Massage stimulates the circulation, and brings the blood from the inner centers to the surface, filling the many minute capillaries just underneath the skin, thus producing a tonic effect, which gives the skin renewed vigor and health.

What to do for a Cut.
If a man cuts himself while shaving, it is usually due to certain causes that are easily avoidable. The principal causes are six in number:
First—Attempting to shave with a dull razor.
Second—Using a sharp pointed razor.
Third—Shaving with a razor that is too hollow ground, so that the edge springs and bends on the face.
Fourth—Holding the razor improperly.
Fifth—Shaving upward against the growth of the beard.
Sixth—Shaving in too great a hurry.
If you will avoid these mistakes and exercise proper care, you will seldom cut yourself. But when you do, it will be well to know how to treat the wound. If it be slight, the bleeding may sometimes be checked by using pressure. Covering the fingers with a towel, simply press the cut together. If this does not stop the flow, use an astringent. The styptis pencils, made especially for this purpose, are the best, and may be obtained at any store where barbers’ supplies are kept. In case you should not have the pencils, alum may be used. In any event do not be discouraged, for such accidents sometimes happen to the best barbers.

Bronze age razors

From Vere Gordon Childe’s book “The Bronze Age” (1930):

It is quite possible to shave with a flint blade, and some predynastic flints were undeniably utilised in this way. The early Egyptian metal razors exactly copy these flint forms. One type, confined to the Early Dynastic period, was rectangular with four bevelled edges. Another form, going back to Late Predynastic times, looks like a broad double-edged knife with a short tang. Probably most were sharpened along one edge only, as is certainly the case with the specimens from Queen Hetep-heres’ tomb. A very similar little implement has recently been found in early Sumerian tombs. The Mesopotamian razors, always unfortunately in bad preservation, are regularly found in pairs; it is uncertain whether both edges were sharp. In the Aegean area the earliest certain razors date from the LM III period. The majority are one-edged (Fig. 81) but there are double-edged specimens in which the handle was riveted directly on to the blade without a tang.
The majority of European razors belong to the same family. In the earlier graves of the so-called Siculan II period, containing Mycenaean vases imported from Greece, we find a long blade with slightly concave sides and an indentation at the lower end (Fig. 83). The purpose of the indent was perhaps to allow the forefinger to feel the skin while shaving. In any case it is a prominent feature in nearly all European double-edged razors. In contemporary North Italian implements the indent is much more pronounced, and, above, a wide slit separates the two blades. An openwork handle, generally terminating in a loop and cast in one piece with the blade, was attached to these Italian razors (Fig. 85). They belong to the Middle Bronze Age. Rather later a small group of razors appears in Franconia and Western Bohemia with a very broad double-edged blade, sometimes at least divided by a slit near the end, and an openwork handle cast in one piece with it (Fig. 86). Crude razors of this pattern are found at a relatively later date in Holland and Eastern France (Nievre and Rhone). But the contemporary Central European razors of phase E have already grown into developed horseshoe-shaped blades (Fig. 87).
In Upper Italy, on the other hand, during the Late Bronze Age and first phase of the Early Iron Age (Villanova culture), the razor assumes a rectangular outline, preserving the indent in the lower end as an almost circular aperture and provided with a loop of twisted wire riveted on to the blade as handle (Fig. 88). The same type is found in South Italy and Sicily, but in that island a type, derived from the earlier native form, but with wider blade, more pronounced slit between he edges and a flat tang for handle, is also encountered in the later tombs of the Siculan II period. Similar forms occur in Southern France (Arige and Charente) and probably give a clue to the ancestry of our British razors.
The latter resemble a maple leaf in form. A tang to take the handle projects from the base of the blade and is often continued downwards by a wide midrib along its face. In the opposite end is a deep V-shaped indent and just behind it a circular eyelet. Though generally Late Bronze Age in date, one such blade, though without the round eyelet, was found with rapiers and palstaves in Scotland.[38] It is generally believed that these razors belong to the group of foreign forms introduced into Britain by invaders arriving at the beginning of the Late Bronze Age. The affinities of our razors in any case seem to lie rather with Sicily and the Western Mediterranean than with the countries east of the Rhine.
While the standard European razors of the Bronze Age were double-edged, there is a series in Scandinavia with only one blade. Such are doubtless in the last resort derived from the normal Mycenaean implement (Fig. 91).
