Tsunehisa srs13 -- the new akifusa etc?

[chiffonodd]

Is the tsunehisa srs13 the successor to the akifusa (et al.) srs15? It looks fairly similar but difficult to tell because I can't find a great comparison angle. If the srs13 is the successor, is the srs15 line done for?

Also, anyone compared srs13 and srs15 in use? Zknives says that 13 is a newer version that contains slightly less carbon.

So I know none of us ever remember, but ZKnives also has some knife reviews posted. Akifusa was one of his first.

Akifusa(Ikeda) Gyuto 240mm(9.5

I stumbled on his write-up shortly after buying my Akifusa from Epic Edge a couple years ago and it helped explain why I could only find the brand at Epic Edge.

I've noticed the Tsunehisa line popping up at places too. My understanding is they are both made under the same roof so maybe this is their way of capturing more of that market while not stepping on the Akifusa brand.

The ZKnives review also explains that SRS-13 is just a tiny-bit altered -15 and was done so Spyderco could use the steel. I do know they used SRS-13 so it may fit. I'd bet that you'd never know the difference since the composition is so close and they come out of the same house.

My only question about the Tsunehisa line is if it is ground as thin as the Akifusa line. The couple of Tsunehisa's I've had were thicker than my Akifusa but both of those were in ginsan. I always took the Harukaze line to be thicker, the Tsunehisa somewhat thinner and then Akifusa the thinnest. I may well be wrong on that though.

Well I must be a fellow dinosaur because my first jknife was an akifusa srs15 santoku from Epic Edge back in 2015 when I lived in Seattle. Time flies!

Fellow dinosaur reporting I purchased a 240 Haruyuki SRS-15 from Knifewear and then wanted a 210 but couldn’t find one that was a little bit taller so I ended getting a SRS-13 from Yoshihiro. I’m guessing it’s rebranded Tsunehisa. We’ll see.

@TokushuKnife any insight into the grinds on these? Especially compared to the other Tsunehisa steel offerings? Curious if these are any thinner.

Fwiw in the meantime while we wait to hear back from @TokushuKnife, here is the choil shot of the 240 tsunehisa from the listing at Tokushu Knife compared with a choil shot of a 240 akifusa from @dafox's recent sales thread. Looks similar enough although the angle is not optimal for comparison.

I remember it.

It was why I bought an Akifusa as my first good knife.

All of the knives mentioned should be from these people:

Brand-global | Hokiyama Cutlery

3 characteristic categories of tradition, practicality and innovation.

www.hokiyama.com

They work for everybody everywhere and keep a good portion of the party going.

 

[Jovidah]

The Hokiyama is strong with both Tsunehisa and Akifusa but it's hard to really say anything conclusive.
For example it's not out of the question that knives from other manufacturers qre also sold under the Tsunehisa brand. Just because something has the same steel and looks doesn't mean they are the same.
After all, not all white 2 knives are made by Mazaki - even when the majority is.

SRS13 and SRS15 are likely by Hokiyama tho, they had exclusive right to SRS13 and still have it on the 15. Only couple other makers do SRS13 like Takeshi Saji and Kurosaki
