From industry leaders, Konosuke Sakai, the semi-stainless GS+ core and stainless cladding make for the perfect entry into carbon steel, or Japanese knives as a whole. Thicker than their other lines, but still thin enough behind the edge for better initial cut-feel.
We have received a handful of B stock from Konosuke with the latest shipment (June 2026). All of this line does have some light scratches in the nashiji but the B's are slightly more than normal. Please select which variant :)

I have built a very strong relationship with ProTooling. Paul (the owner) has a very good attitude and that reflects in the products he stands behind. He provides only the best quality through all of the good relationships he has been able to grow throughout the years with the top craftsmen in Japan. He and his staff are amazing. Keep up the good work.
