Men do a lot of shaving and have relatively coarse facial hair so they need good shaving products. The choice of razor and lubricant is a personal one but it is often what a man was shown to do as a young man rather than making a conscious choice. The most popular razors today are disposables.
They have either a fixed or replaceable head and may have one to five blades on the cutting head. Fixed head razors mean that you throw out the whole thing when the blades become blunt. A replaceable head razor allows you to change the head when the blades become blunt. These replaceable head razors are more expensive initially but are cheaper in the long run as the replacement blades are quite cheap.
Disposable razors were introduced after World War One and were literally single use and throw away. They were intended to be used to ensure a good fit for gas masks so although they were only good for one shave; they were doing an important job. In 1960 stainless steel blades were introduced in disposable razors making them more economical as they could be used on multiple occasions. Wilkinson, the ceremonial sword makers were responsible for this innovation and the disposable razor has not looked back since. They now dominate the shaver market but I was intrigued to learn that the best shave possible is not from a disposable (despite those terrific hair cutting simulations on the ads).
A straight razor or a double edged safety razor gives the best shave provided that the blade has been properly sharpened. The correct term for this is stropping. Shaving razors are very thin and need to be stropped before each shaving to straighten and polish the blade. A strop is a flexible strip of canvas or leather. Shaving razors are the thinnest blades used in a household everyday and they are very sharp which is the quality that gives the very good shave, being sharper than even a brand new disposable razor as well as wider.
A straight razor has two parts, the blade and the handle and these may be hinged so that the blade folds up into the handle. They do come is different sizes so that you can choose what suits you or the other option is a double edged safety razor which is a bit safer to use than a straight razor but can still be sharpened in the same way.
The third type of razor is the electric shaver, which have the option of being used on dry skin. This makes them suitable for use away from home. For example some men grow a heavy beard may need to shave more than once a day; an electric shaver makes this convenient to do in the office or car.
