    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 Perfect Shave I have been using kingofshaves products for a number of years but the K4 four blade razor is the smoothest I've ever used. Perfect!!

Rated 3 out of 5 by from Bring back the Azor Razor I have been using KOS products for a number of years, including the Azor Razor, K4 and K5 systems. The K5 has the greatest tilt range and the smoothest tilting action, but the blade gives a very uncomfortable shave under the chin, even with my very light beard. The K4 gives a more comfortable shave, but the spring loaded plunger in the handle soon jams, making the tilt action erratic. The solution is to replace the handle frequently, which makes the K4 system more expensive than the K5. The discontinued Azor Razor system relied on a flexible joint in the handle for the tilt facility, which limited the range of tilt, but gave a very smooth action, with a resultant comfortable shave, especially with the the more expensive optional metal handle. My current solution is to use the K4 for my face and the K5 for my head.

Rated 5 out of 5 by from THE...KING of Shaves. I have the unfortunate combination of sensitive skin and a heavy beard growth. Over a number of years the K4 blades have given me consistently close shaves without the discomfort of razor rash. With competitive pricing and fast delivery all round a superior product.
