My yoshikane nashiji skd gyuto 210mm arrived recently. I didn't think chopping onion would be this fun. Before, I used the Mercer 8 in daily, so I am more used to the rocking motion. Flatter profile of Yoshikane is not really made for rocking. I been told before that rocking motion is not good for the knife anyway, so I will use this chance to better my knife skills. I don't think my wallet will appreciate this new hobby, but I think this hobby is here to stay.
