This is an interesting one. I really did more drawing than typical to get the width on this blade and the depressions from the fullering tool are apparent in the cladding.

  • Blade: 229mmx54mm Apex Ultra/15n20 san-mai ~67 HRC, 2000 grit finish
  • Neck: 15mmx20mm
  • Handle: 127mm, tapering from 25.8mmx23.8mm to 22.7mmx19.2mm, burned oak, oil finished and waxed
  • POB: 50mm from handle
  • Spine: 3.3mm at the neck, 2.24mm at halfway, .60mm 1cm from the tip
  • Grind: flat to convex RH bias
  • Weight: 168 grams
  • Relieved choil and spine
  • Edge: .1mm
There is a small mark on the left side near the spine that I would have needed to remove most of the cladding to get out, so I opted to leave it. I'll have a close up shot of that coming soon. It won't affect function, but I just figured I'd make note of it. In light of that small mark I'm reducing the price of this knife just a little.

Asking $400 $375 $360 U.S shipped with insurance anywhere in North America, for shipping to Europe or Australia I will cover the first $32 U.S of shipping

The little dimple on the left face. It seems my fuller picked up a piece of scale or something at some point. It's quite minor, not even a half mm deep.

Patina shots were requested. This is after some thinning that turned out to be just polishing, then it sat for a couple weeks.

Under the microscope you can see mild oxidation at the cladding boundary. Not sure which steel is browning exactly.

Sorry about the difference in lighting conditions. There was no blue in the before.

All surface imperfections are the fault of the current owner.

Thank you Meng! I've been aching to know how the 15n20 patinas in comparison to other steels
 
Much delayed. Better late than never.

Not a 16k polish; instead 4K SG HC.

So, today I polished in circles deliberately because I kind of liked the way the reflections follow the light when you wiggle the blade. It feels almost three-dimensional. Or at least like one of those lenticular prints.



Then I applied a chili sauce I found at the back of the fridge, courtesy of Ah Tan wings

Note darkening in spots. I think that was where the sauce was gloopy.

Final result

I feel embarrassed to post this on the same day as @KasumiJLA posted his masterpiece

Let’s call it an early prototype, I will come back to this.

  • SG 500
  • JKI 1000 DR which went shinier than the SG500
  • SG 2000

CONCLUSION

1 hour and 20 minutes is not enough time to get the scratches out
