Does anyone have any experience using both the nenox g-type and S1? If so, did you notice any big difference in performance from the steel? I have a S1 gyuto that I am very happy with and use almost everyday at work.I've never used a g-type. I'm thinking about getting a nenox sujihiki and just wanted some opinions on the s1 vs the g-type and if it is really worth the extra money. Thanks.
