The Toyama gyuto and petty combo includes two hand-forged Japanese knives crafted in Sanjo by 83-year-old blacksmith Shuji Toyama. Both knives feature Aogami #2 carbon steel cores with iron-clad Damascus construction. Toyama knives are known for their exceptional cutting performance, with blades that cut cleanly through ingredients with minimal resistance. The 244mm gyuto handles general kitchen tasks while the 153mm petty is suited for detailed work like trimming vegetables and slicing garlic. The heat treatment brings out the best qualities of Aogami #2 steel, balancing hardness for edge retention with enough toughness for daily kitchen work. The steel sharpens easily and maintains its edge through regular use. The iron cladding will develop a natural patina over time with use.
