VG10 Construction techniques

[Budrichard]

The Nakagawa VG10 Sakimaru I recently purchased was described by the seller as

• • Construction: Awase (Kasumi)
  • Grind: Single Bevel (Right-handed)
  • Hagane (Core Steel): VG10
  • Jigane (Cladding): Stainless Steel
  • Hardness: 60-61 HRC
  • Hand-forged, hand-ground, hand-sharpened
• Blade Finishes:
  • Kyomen (Mirror)
  • Kasumi Polish

A Nakagawa Wa-Gyuto VG10 I am considering purchasing is described as

Steel Type of Cutting Edge:
VG10
Steel Name:
VG10and Soft stainless
Forge Welding:
Interrupt Welding (Warikomi constraction)
Forging Method:
Free forging
My question is what is the difference between methods or are both construction methods the same but with different descriptions?
Thanks you for any assistance!

Nakagawa is going to use the same pre cladded vg10 for everything. Warikomi vs San Mai is the whether the cladding extends to the spine or not.

If I were to guess, they are both probably sanmai and the warikomi description is incorrect

Sanmai for a single-bevel knife? I've only ever seen or heard of ni-mai for that.

Nakagawa does make VG-10 monosteel knives as well (whether conventional zenkô or differentially-tempered but not differentially-hardened "honyaki").

TF makes sanmai single bevel knives.

I doubt he laminate 2 stainless by himself, it’s kind unnecessary as Takefu is just gonna do it a lot better

One thing is Japanese makers use Warikomi kind too liberally, for anything cladded, a classic Wakimori is kind like Sugimoto where hard steel is inserted half way, but many laser cut stainless will also have hon warikomi 本割込み written on them, here’s a video with Okubo doing some Warikomi
