I found the C plate with the KAI to be a little harsh until the third shave. After that it's been a smooth and efficient shave every time. I have the B plate. Once I change out this blade I may try another KAI with the B plate and see how I like it.Hi @MarkB. Curious about comfort and efficiency of the C plate w/ the Kai? I have both the B plate, and I've shaved with the Kai. C has positive blade per Karve website, and Kai seems slightly larger than average blade size. I love the B w/ Kai because of mildness and efficiency for me. I may be splitting hairs to think that there's much difference. Looking for qualitative reply. Just curious about your thoughts on C plate/Kai both for comfort and efficiency?? Thanks
