I have a KCG and I’m still in the process of finding the best blades for it. I have feathers and derbys, and the feathers are too sharp for my liking but the derbys seem to be okay. I have a homemade pre shave oil (castor and olive oil and bay rum essence) and stirling bay rum soap. If I do everything right I can usually get an okay shave but haven’t really managed anything stellar because my skin is super sensitive. Anyway, to the question on hand. Out of curiosity I’ve tried barbasol for a quick shave a few times, whipped into my brush and one time watered down. But every time I try to use it it seems as if the shave is ansolutely terrible, and it leaves me horribly red throughout the neck area. My old can of gillette goo was no different. Is it something with the razor just not being able to play nice or is there another factor I’m missing?
