I'm a cold water shaver. I've recently been adding ice cubes to my preshave soak of my razor and brush and my shaves have been better than ever. After rinsing each stroke, I dip the razor back in the ice water and proceed to the next stroke. Idk what motivated me to try it, maybe just curiosity to how the shave would be with water as cold you could get. If you are a cold water shaver, give it a shot! I've been adding ice cubes for a week now and love it.
