READ IMPORTANT DELIVERY OPTION INFORMATION

Made by Hiro in Seki Japan with stainless clad aogami 2 western handled blades with quince, mosaic pin and black and copper spacers. 

We were able to get decent information on these, it seems these were dead stock  somewhat recently handled with older stock blades. 

Blades are hand ground thin with a convex face, there is a smoothed spine and semi smoothed heel, handles have nice fit ups. Some blades need a little straightening but none are badly off. 

This is a stainless clad reactive carbon steel. It should be mentioned that extra care is required, as only the cladding of the blade is stainless and should be dried immediately after use. The core will develop a dark patina with usage, but any orange rust should be removed with a light abrasive.



About This Knife

General Purpose

Good for veggies and boneless protein

Avoid Bones & Dense Foods

If you can't bite it, don't cut it.

Stainless Clad Carbon

Reactive core steel between two non-reactive layers.

Convex Grind

Super smooth cutting feel.

Santoku

Santoku means "three virtues," referring to its versatility with meat, fish, and vegetables. It has a shorter, wider blade than a gyuto with a flat edge and slight curve that excels at chopping and low mincing. Ideal for home cooks due to it's smaller size range for general prep across a range of ingredients.

  • This is a stainless clad carbon steel knife made from thin, hard steel
  • Hand wash and towel dry after use. Do not air dry or place in the dishwasher.
  • Expect oxidation (color change, staining, spotting) with use.
  • Prolonged exposure to moisture or food debris will cause rust; remove any rust with a light abrasive.
  • The carbon steel edge will oxidize with use and may rust if left wet. The stainless clad outer layers resist corrosion but can still stain with prolonged moisture exposure.
  • Avoid twisting, scraping, or use on dense or hard foods and surfaces to avoid early dulling and edge damage. If you wouldn't bite into it, don't cut it with this knife.
  • Use on wooden cutting boards only. Do not use bamboo, plastic, stone or metal cutting surfaces.

Dive Deeper

Medium-fine finish

We recommend sharpening by hand using whetstones starting around 1000 grit progressing to at least 4000 for this steel type and edge geometry. Finish with a monodiachrome strop for a smooth cut with a substantial bite. Finer finishes are possible, but the knife may slide on smooth foods and overall edge retention may suffer. During repair, use a super coarse stone to pass chips quickly to help keep flat bevels.

  • Avoid pull-through sharpeners and non-water-cooled mechanized systems.
  • Strops and ceramic honing rods are preferred for as-needed edge maintenance. If you have to use a honing rod to be able to use the knife comfortably, it's time to sharpen the knife.

Aogami 2 (Blue Paper #2)

Carbon (C): 1.1–1.2% | Tungsten (W): 1.1–1.5% | Chromium (Cr): 0.3%

Aogami 2 is a well-balanced Hitachi carbon steel commonly hardened to around 60–63 HRC—about one point softer than Aogami 1—which gives it excellent edge retention with added toughness. Its slightly lower carbon content means it loses its razor edge a bit sooner but holds a strong working edge for long periods, making it a favorite “sweet spot” steel for daily-use kitchen knives. More forgiving and less brittle than Aogami 1, it can take thin edges without chipping and excels in hard-use kitchen or woodworking applications.

Though fully reactive and prone to patina, it sharpens easily to a keen, refined edge and responds beautifully to both fine and toothy finishes. Aogami 2 is widely used by Japanese makers for workhorse knives and is often stainless-clad for user-friendly maintenance.
