The entire Seki lineup is getting it.
Okay, I know I can look this stuff up, but, in a nutshell, what excites you about Seki K390? I only ask because I am a big Seki H1 Salt fan. I assume this is very opposite, and it must have some really good qualities.
Where can I find this info?
And do you know if the blades are satin or DLC coated?
Hoping they offer the endela in it. Otherwise I'm definitely in for a delica.
You might want to watch this, then. There are a lot of people thinking that fracture toughness is the same thing as resistance to damage. Extreme strength of A11 class steels allows for high edge stability, and can allow those steels to shrug off damage that might damage tougher steels.k390 has 2.5% carbon, and a whopping 9% vanadium... which should be an amazing steel for edge retention, but at the cost of extreme chippyness

personally, I won't be getting anything with this steel, I expect it's toughness might be similar to maxamet (which has 2.15% carbon) ... however it's 'supposed' to be slightly tougher than m390. I won't believe that, until @Larrin says so after testing ; )
m390 sits at about 5 ft lbs, while maxamet is around 2.5 ft lbs... both are too low (imho)
for now, cpm-m4 (with toughness of 15 ft lbs) is my edge retention top steel
but I'll enjoy reading stories about k390 steel when people on bf have tested many examples

I think the Reveal has this information, but it has been discussed on the Spyderco subforum, here, and on the Spyderco forum. It is very exciting. The Endura, Delica, and Dragonfly are going to drop any time now.Where can I find this info?

I generally like the way tool steels behave. This is a tool steel on steroids. It holds an edge for a very, very long time. It is a lot harder to sharpen than most carbon steels, but it is not as bad as many high end stainless steels. It is also can take a very nice thin edge for slicing without failing. This steel makes M4 class steels obsolete.Okay, I know I can look this stuff up, but, in a nutshell, what excites you about Seki K390? I only ask because I am a big Seki H1 Salt fan.

It is not in the least chippy, not even remotely. Larrin has addressed this steel in several articles, either directly or indirectly.
In for a Dragonfly and Manbug! Shouldn't be long now. Interestingly the Ladybug K390 was released several weeks ago.
I haven't seen any toughness test of K390 in Larrin's website. In fact, in his article about the edge retention of 48 steels he wrote :
>>>I have tested the toughness for all but 7 of the steels: Z-Max, BD1N, K390, S125V, S90V, S60V, and Vanadis 8.
So we don't know what is the real toughness of K390. All we have are the values displayed on Bohler site.
In his article about How to Pick the Best Steel for Every Knife Larrin seems skeptical about the toughness claims of Bohler. He wrote:
>>>There are a few different 10V replacements including Bohler K390 and Uddeholm Vanadis 8, those steels are more expensive but they are advertised as having superior toughness. If future toughness testing confirms superior properties of K390 or Vanadis 8 I may change my recommendation.
