for me the kai is far superior to any feather-seems a bit less thick -so more flexible?? but super smooth shaves each and every time and seems to stay sharp for a long time as well-so more durable than any feather -as an added bonus-
Best blade out there in my opinion the Kai Pro Touch MG, next would be the Feather Guard, then Schick P’s. Worst was the Feather Soft. Trouble with the Kai’s is they are hard to get. This just got me searching and I managed to nab A pack for £17.99 inc postage. Need a good supplier, Connaught would be the go to but they have been out of stock for a while now.
