Suminagashi steel

[Roefisher]

Does anyone have experience with this steel type?

It certainly looks beautiful with the multi layering, but I would like to know if it's practical for outdoors use, such as woodwork and vegetable/fish cutting. I am careful with protecting carbon steels, but my main query would be in the steel edgeholding and sharpening.

Here's a quote about it "The blade is crafted from Japanese Suminagashi steel. This laminated steel consists of a central 1.5mm layer of "white" high carbon steel surrounded by a total of 22 layers of a low carbon steel on either side. The blade is hardened to Rc60. This steel is super sharp and edge life is outstanding. This steel very expensive and is very highly sought after by knife makers in Japan. The handle is Desert Iron wood and is regarded as one of the finest knife handle materials available. The fittings are all brass. The knife measures 22.5cm long. The blade is 11cm long and 5mm thick."

Any comments and advice are most welcome,

Mark

It looks like laminated steel,I saw a hocho blade made out of the same stuff.The Japanese are particularly good at producing multi laminated steel.I dont know what the durability of the edge would be like,but at rockwell 60 it should be darned good. I'd bet my months salary that it is VERY sharp.
With dessert ironwood as well! I would

It should be good steel, The Japanese rate there steels by quality and thats all that the colours represent. White steel is good steel

But as for design 5mm seems a little thick to me, 5mm seems thick on an f1 but this is 5mm thick two 3rds down the blade?

Just my opinion

i think the knife is made by Scottish maker gregory venters who spends a lot of time researching the steels he use's.if gregory rates it you can be rest assured,its is as stated,i am an admirer of gregorys work as he strives to be different than other makers.

It's nice gear, and forged a little the defining lines between those layers "diffuse" a little... Here are a pair of forged steak knives I made in the material...

The only concern I would propose is the hardness of those protective, outside, layers...

For those who might not know the steel is basically a lamination of 22 layers of steel with a central layer of "White Steel." The outside layers there to protect the hardened core.

looks gorgeous to me as do Stuart steak knives. Rc60 is jolly hard, hard means sharp edge and good edge wear resistance but also brittle. The softer layers are there to protect the hard core but it would still be possible to chip bits out of such a hard edge if you abused it. Great for veg and fish and shaving green wood but don't go chopping at dry wood with it. Why not use a cheap frost sloyd for your woodwork? Desert iron wood is very dense and heavy so it will feel really solid and well balanced.

Stuart are you a comercial maker, do you have a website?...don't supose I could afford such a knife but I would love to look at more and dream.
edit...just spotted the site link...nice knives stuart!
