Hitachi #2 Blue

What is that per knife....like, 9-15 bucks? Pfft....we spend that on stainless without a second thought.
 
if you cut carefully and did some forging you could get 9 240 mm gyutos from it so that would be 20 bucks a knife.
 
It is a big enough piece that you can have it paid for with a few blades, make a few more, and still have a couple of blades worth to sit in the corner until it's all gone from Aldo. Then undercut the dictum price for the next person who posts 'where can I get Hitachi Blue Paper Steel in the US' and turn a couple of bucks that way....

Come to think of it... maybe I should order another while I'm at it...

This Hitachi #2 blue is different than Blue Super steel correct? If so, what are the differences between the two?

they are very nearly the same. v-toku 2 has some vanadium and nickel and a little more manganese. in test cutting in my shop v-toku 2 takes as fine an edge and seems to hold it slightly longer on a rope cut test.
 
It's all about the harmonium....

Mete started it....:)
 
I was thinking that .140" might be a bit thick....but I believe with a gentle taper, it will make a very nice chef's knife.
 
Those of you who know about the Phosphorus content of steel better than I......does that look right to you? A P content of 0.25% for Hitachi Blue steel? Aldo has the same listed on his site....but was wondering if that is not a misprint....as in should be 0.025% ? Just wondering...

Well......looking at the Chromium I have the same concern. Is that really 0.04% ? I would think that should read 0.40%. Really wondering.....

You could beat on em a little first. ;) Or use this thing called a grinder... lol. J/k...

Seriously though. Beggers can't be choosers. A little more work is worth the price not starting with at-thickness stock to boot. But, one of my requests is actually for something thicker at the spine with more width in the body. I don't use em worth a darn (can't cook if it ain't on a fire) so I am relying on customers' input and WIP's here for design.

if it is not a miss print then the steel is f**ked up unless it is something other than blue steel
 
Your right Stacy. It's actually 0.013. I tried to put up the certs but the files to big with all the Japanese characters.
 
I'll be buying a sheet this week with those alloying elements, just for the curb appeal. I'll invest the time into some coupons to get a great heat treat! :thumbup:
 
The chemical element harmonium? I can't even believe that's somethin' that's real!
