Heritage and Character

The 300mm chef's knife is the preserve of professional kitchens and confident home cooks - at this length, the knife excels at breaking down large proteins, slicing full loins, and working through oversized vegetables where a shorter blade requires multiple passes. Minamoto Masakane's carbon steel at this length is particularly impressive: maintaining consistent hardness and grind geometry across 300mm of blade requires precise heat treatment and skilled grinding. The "Minamoto" prefix is a traditional claim of the highest lineage in Japanese craftsmanship. A 300mm carbon steel chef's knife from this maker is not a shelf piece - it is a working tool that happens to be extraordinary.

• Dry immediately after use to prevent rust
