Overview
The Hatsukokoro Kokugei Blue #1 Kurouchi Santoku 165mm is a compact Japanese all-rounder built around premium Aogami #1 carbon steel. The rustic black forge finish gives each blade an unmistakably handcrafted character, while the mono ebony wa handle adds a clean, understated finish and comfortable control.
Its 45mm heel height offers useful knuckle clearance, and the 165mm edge is nimble enough for smaller boards while remaining versatile for vegetables, herbs, fruit, fish, and boneless proteins. A substantial 4.0mm spine at the heel tapers to 1.5mm at the midpoint and 0.8mm near the tip, giving the knife a confident feel with a progressively finer geometry through the blade.
Common Questions
Q: What is a santoku best used for?
A: Santoku means “three virtues” and is designed for versatile everyday prep. This 165mm model excels at slicing, dicing, and mincing vegetables and boneless proteins.
Q: Is Blue #1 steel stainless?
A: No. Blue #1 is a reactive high-carbon steel valued for its fine edge, sharpening response, and edge retention. Hand wash the knife, dry it immediately, and never place it in a dishwasher. A natural patina will develop with use; for longer storage, apply a very light coat of food-safe camellia oil.
Q: Will every knife look exactly the same?
A: No. These knives are handmade, so the kurouchi finish, measurements, weight, and natural ebony grain may vary slightly from piece to piece.
