H-1 has a competition alloy?

The two steels have similar properties. I would love to hear more from experienced members on the two steels. I know H1 is rolled in the manufacturing process. This alloy is a powdered steel, does that make a difference? What do you think?

If it is actually suitable for the applications outlined in that sheet, it could well be a good dive knife steel. It would certainly seem to be a good candidate for testing in that arena.
 
I'm not sure PUD 177.0, a.k.a. Nitrobe 77 will be as stain resistant as H1 is, h1 has 6-8% Nickel in it, which Nitrobe/PUD 177.0 doesn't.

On the other hand, Nitrobe 77 is plenty corrosion resistant, and should do better in edge holding department, 0.9% Nitrogen vs 0.1% in H1, and some Niobium in it.
PUD 177.0 vs H1 steel composition comparison.

Shinichi Watanabe is is the only maker I know of currently making knives out of that steel - PUD 177.0 petty, I'm pretty sure he can make utility/hunting knife out of it, besides kitchen knives. Haven't asked yet though.
 
Powdered steels are reported to have a finer grain structure. This is supposed to allow the edge to get sharper and stay that way for longer since the little microscopic bits of steel are "woven" much tighter.

In practice, however, I don't notice any significant difference between the powdered steels I've used compared to regular steels. Edge geometry and thickness is infinitely more important than the type of steel. This new steel technology might be "better," but I doubt it's worth the price premium for a regular user.

That's a very generic statement to dismiss any alloy. Depends on the intended use and what are we comparing to. Plus, it also depends on the "regular" user's use habits and sharpening skills.

Des Horn also uses it for folders......I have one
 
twoism - powdered steels have smaller and more uniformly distributed carbides which gives it a distinct advantage . It does not necessarily have smaller grain size.
