    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 product delivered in green packaging Big fan of KoS razors. Great that they’ve cut out all plastic packaging - delivered in the smallest cardboard box and a tiny bit of paper wadding.

Rated 5 out of 5 by from Nice design good shave I’ve had my K4 Retro for a few years and really like the design, so buying some more blades was a no brainer (also really like what King of Shaves is trying to do against waste).

Rated 4 out of 5 by from Basic, old school, but good The 4 blade packs are great because I can buy in bulk and have them to hand when I need them. This has been excellent during lockdown because I have had all my KoS items to hand for the past 6 months. No Worries. I have now stocked up for the next 12 months, because I want to, and incase we have another (Winter) lockdown [Anyway, how much space do a razor blades really take!]. Whilst the blades don't have all the bells and whistles, you have to ask yourself "Do I need that?". Sometimes keeping it simple is what you need. I shave daily and what I value is a good shave, which is why I have used King of Shaves products for longer than I care to remember. No blades will never be as amazing as the KoS Azor, but as you can't get that any more, these have been my razor of choice for the last year. The delivery and price is great, not having to worry when I need to buy more is awesome and the product itself suits me and my style. The shave is what you need in a razor, clean, sharp, but safe. It's not the next iPhone or the next big thing in shaving, but as I said you don't need that, you need a dependable product that does what it says it will do. This is it.

Rated 4 out of 5 by from Good quality blades Having only recently run out of the exceptional Azor blades, I went for the K4 as previously found 4 blades smoother than 5. The razor itself takes some getting used to as it handles differently but the blades cut close and smoothly.
