King of Shaves have recently introduced two new cartridge razors. The KOS Five blade and the KOS Retro 4. The KOS Five blade handle has been sourced from a Chinese manufacturer, and was the first KOS handle not to be developed internally. The actual handle and carts are available from MERS marketed as the T- Series/Taranis Futur5. The Retro 4 features Bic Flex 4 carts. Neither of this two products have any involvement of their former partner Kai.
What has happened to innovation at King of Shaves?
I think Kos razors are in a bit of a crowded market lately, they certainly pricey in some cases, selling some Chinese stuff maybe just a survival mechanism I suppose.
