This should be educational. Is there a rookie category? So far, I have only used my 8k as a finisher on the handful of razors I've honed, to mostly good reviews. I have a nice comparison, with 2 TI Le Canadien 6/8s, one done by Maxi and finished on the Escher,.one done by me and finished on the 8k. I've been curious to try the one-stone 4k/8k method.
