I have little doubt that Goko makes those sorts of knives, but even if CKTG were to try to get some, lead time is likely to be long and the ETA uncertain.
I have and love the Goko as well but there are a number of manufactures that use similar steel, have great aesthetic character, and perform amazingly. You might post a recommendation request in the knife recommendation forum: knife-recommendations-q-a-f4.html
. I am sure there are some great, complementary options to the Goko. Unfortunately, I do not have a suji, so will refrain from proffering recommendations, but good luck with the search.
