Sentan built this petty around SLD, a semi-stainless tool steel that sits in a genuinely useful performance range - tougher than most carbon steels, more wear-resistant than common stainless options, and responsive on the stone in a way that harder alloys rarely are. The san mai construction wraps that SLD core in stainless cladding finished in nashiji (pear skin) texture, a fine matte surface that reduces drag and gives the blade road a refined, purposeful look. The polished SLD edge bevel stands out cleanly against the cladding, making it easy to see exactly where the work happens.
The 180mm petty is one of the most versatile formats you can have at the board. Long enough to handle most slicing and prep tasks, narrow enough to stay nimble on detail work - breaking down a chicken, slicing proteins thin, or working through aromatics with precision. At 61 HRC the edge holds well through real use without becoming fragile or difficult to restore. The olive wood handle sits comfortably across grip styles, and the blue acrylic ferrule is as durable as it is distinctive. Spine and choil are polished for a smooth feel during extended cutting sessions.
Care Instructions: SLD is semi-stainless and may develop a light patina over time - this is normal and does not affect performance. Hand wash and dry immediately after use. Do not store wet or leave the knife in a saya while damp. Avoid hard or frozen foods. Use a wood or soft synthetic cutting board only.
