This is part of a 7-knife liquidation to help fund my new obsession - hifi audio. Do yourself a favor and stay away from audio. All 7 of these knives are NIB, never used, priced below what I paid, mostly in 2017 and 2018.

Note: posted on CKTG and KKF
Video at bottom provided by Mert as he was finished making the knife.

Bump. I thought this one would go quickly. Never used. Less than what I paid for 5 years ago.

Honyaki is hard to see but it's there. I didn't want to etch it because I don't know what I'm doing. Shape is almost identical to my Masamoto KS, but this one, the blade is even thinner at the tip. Here is a breakdown on the German SC125 steel, which Mert really likes a lot. Here are his comments:

W2 was used by many makers due to being close to pure simple carbon steels that are used in Japanese kitchen knives, especially hitachi white 2 . Hitachi white had the edge compared to the W2 due to being more clean in terms of unwanted trace alloys like phosphorus and sulphur. And hitachi white2 had more consistent carbon content where the W2 could be between .90 to 1.4 . So makers had to adjust their heat treatment with each different batch.

Sc125 is made by Achim Wirtz in Germany in very small amounts and it is a lot harder to get and a lot more expensive. It is not as forgiving to forge due to extra carbon content and more tricky to heat treat with consistent hamon . .... It is lot more abrasion resistant than Hitachi White 2 or W2, has less impurities and more carbon. It is a better steel in my opinion, hence my reason to switching to it.

Here is a chart of chemical comparison of the 3 steels

fyi w2 is a completely different steel compared to white 2, even though that is how it's abbreviated sometimes. It's a tool steel, with some vanadium and tungsten as you can see. Closer to something like aogami super (kinda not really)

Expensive stuff like honyaki can take awhile to find the right buyer, and usually for a bit less than what you paid. Nevertheless this looks wonderful and in a cool steel you don't see often for honyaki. Someone would definitely be happy grabbing this.

Thanks. I added Mert's actual comments about SC125 to the above post. I think he concurs with what you said about W2 and White 2.

White 1 is likely a better comparison

I am requesting moderator to close this thread. The knife is going back to Mert for his updated hamon treatment. The Hamon is there, and it’s easy to see in person, but it doesn’t photograph well. Mert has very generously offered to use his latest approaches to improve that aspect of what is already a spectacular knife.
