Fujiwara Denka Petty 120mm
The Denka series represents the most performance-focused expression of Fujiwara’s craft. Forged from Super Blue (Aogami Super) carbon steel — referred to by Fujiwara as Chigusa-kō — and hardened to a high level, the Denka delivers exceptional edge retention with a crisp, assertive cutting feel.
At 180mm, this gyuto offers compact precision with serious cutting authority. Agile and responsive on the board, it suits cooks who prefer a shorter blade without compromising performance.
Like all Fujiwara knives, it is built first and foremost for how it cuts.
Important – Please Read Before Purchase
Fujiwara Denka knives prioritise steel performance and heat treatment over cosmetic refinement.
• Tool marks and visual irregularities are normal
• Bevel polish may vary
• Spine and choil finishing may be minimal
• Each knife will differ slightly
These characteristics are part of the maker’s approach and do not affect cutting performance.
Denka knives are hardened to a high level and are less forgiving than softer steels. Proper technique and maintenance are essential.
Best suited to experienced users comfortable sharpening and caring for high-hardness carbon steel.
Steel & Heat Treatment
Aogami Super (Super Blue steel) is a high-carbon steel alloyed with tungsten and molybdenum, increasing wear resistance and edge retention compared to simpler carbon steels.
In the Denka series it is hardened to a high level, producing:
• Excellent edge retention
• Strong, aggressive bite through dense produce and proteins
• Greater wear resistance than White steels
• High performance stability for a carbon blade
The trade-off is reduced tolerance to twisting cuts, bone, frozen food, or lateral stress.
Used correctly, the Denka rewards disciplined technique with long-lasting, high-level cutting performance.
Geometry & Cutting Feel
The Denka 180mm typically features:
• Noticeable distal taper
• Thin edge geometry
• Strong engagement through vegetables and proteins
• Convex grind characteristics that assist with food release
Petty – Compact Precision
The petty knife is the Japanese equivalent of a paring or utility knife. Small, nimble, and extremely versatile, it’s perfect for tasks that require precision — from peeling fruit and trimming herbs to preparing garnishes and working with smaller cuts of meat. A petty makes the ideal partner to a larger gyuto or santoku.
