I just binned a BIC CP after about 3 shaves. The first one was pretty nice, then it continued to drop from shave-to-shave. I'll be trying their Astor Stainless blades next, I'm curious to see how they'll compare head-to-head, I haven't tried more than one from the same brand yet!I’m excited to try Kai as well. My next 3 will be Kai, Wizamet SI, and BIC CP though I’m unsure of what order yet.
