    Keep out of reach of children. Colour and design of the actual product may vary slightly from those shown. This product was previously called the “Retro 4 Razor”.

  • To maximise closeness, comfort and enjoyment we recommend:

    First wash your face in plenty of warm water ensuring your bristles are thoroughly soaked. Try shaving in the shower.

    Spend 60 seconds massaging your chosen shave prep thoroughly into your beard.

    Using a clean sharp blade, shave carefully with short strokes in the direction of your hair’s growth. Rinse your razor frequently.

    Afterwards, thoroughly rinse skin with clean water. Then pat your face dry with a clean towel.

    Using a moisturiser or a balm after shaving helps to soothe and protect your skin.

Rated 5 out of 5 by from Great shaves I took a chance and bought 48 cartridges and I always get a great shave I have found I can get around 7 shaves out of one cartridge so they are going to last a little while, I am saving a small fortune on these as opposed to other far dearer razors and I am getting a better shave.

Rated 5 out of 5 by from Just as good as the Azor I feel in love with King of Shaves when the Azor was available. I have very thick stubble and all other razors I tried were very uncomfortable to use. My supply of blades ran out a month or so ago so I bought the new 5 blade assuming more blades would be better and was back to square one. I then noticed another review saying the K4 was more comfortable so I took the gamble having just bought the 5 blade system and yes it is just as comfortable as the Azor was. Well it arrived and sure enough it feels great to use, just as good as the Azor and also the handle has a good texture on it to stop is slipping around in wet hands. I don't normally write reviews but this is an outstanding product worthy of the time it took me to write this!

Rated 5 out of 5 by from It works After using an Azor since they were first introduced I was concerned that the K4 would be as good. Apart from a totally different 'feel' it proved to be excellent even though it's heavier. The head is flexible and the grip comfortable. Other than that there's nothing else to say except 'very pleased'.

Rated 5 out of 5 by from Classic look, quality feel, great shave!! I bought this as a trial as I liked the classic look to the K4, couldn’t be happier, after trying loads of brands and subscriptions I’ve never found what I was looking for, til now! The K4 is an awesome razor, best shave I’ve had in a long time! Coupled with the refillable shave gel gave me a great shave!! And usually I throw blades away after each use as they are blunt, had 3 shaves now, and still seems just as sharp as the first time! Keep up the good work!!
