Can anyone say anything about the N-360 blade steel ...........comparing it to M-390 or M-4 ??
Waiting is gonna be a nightmare on this one.

I might get one. :)

It's Bohler N360.

http://www.sten.fi/data/attachments/N360FIN.pdf

Used in the Areospce Industry.

C - .30
Si - .60
Mn - .40
Cr - 15.00
Mo - 1.00
N - .40

It's hard to say what the performance will be like really. I don't think it would hold a candle to M390 or CPM-M4 given that the carbide/nitride volume isn't anywhere near as high. However, Ankerson has tested Bohler's 2 other steels(N680 and N690) to have performance similar to S30V at Rc 60, and Chuck from Alpha Knife Supply mentions that N360 is supposed to be an upgrade to N680, so I would have high hopes for it.

It isn't a powder steel, but instead uses an Electro-Slag Remelting process, though I'm not entirely sure what that does. The gist of what I got is that it makes the steel "clean" and presumably tougher as a result. In theory it could also mean better edge retention as well as the ability to take a fine edge. I suspect you won't ever find any chipping in the edge short of attempting to cut glass or dirt.

wow...that's almost unbelievable. every little bit of new info makes me want one more and more...

N360 actually uses Pressure/Protective-Gas Electroslag Remelting (PESR) instead of just ESR.
Info from one of the Böhler web sites -

Features
• Remelting of consumable electrodes under protective gas (Ar, N2) or pressure up to 16 bar (from 1st melting)
• Two melting stations offset by 90°
• Microprocessor-controlled melting rate
Advantages
• No hydrogen pick up
• Nitrogen alloying up to approx. 0.8%
• Absence of ingot segregations
• Only minor crystal segregations
• Minimum sulphur contents
• Minimum levels of nonmetallic inclusions
• Optimum polishability
• Excellent material properties (virtually isotropic properties, especially with regards to toughness)
• Lowmelting loss of elements with high oxygen affinity
Examples of steel grades
• Plastic mould steels e.g. M303 ISOPLAST®, M333 ISOPLAST®, M340 ISOPLAST®
• Stainless Cr steels e.g. N360 ISOEXTRA®
Examples of application
• Plastics moulds requiring very high polishing finish and wear resistance
Böhler Edelstahl plant in Kapfenberg has 4 PESR plants, capacity approx. 9,000 t/year.

I get the feeling this model is focused on corrosion resistance. They probably went with N360 because of the difficulties in acquiring Vanax 35.

I'm not sure about that. The biggest question is how corrosion resistant is that particular type of damascus.
 
I would say its decent, its a stainless steel variant of damascus. Devin Thomas also supplies CRK with stainless damascus for some of CRK's damascus knives [raindrop damascus and another or two]. So from experience I never had a problem. Especially so if you just do your regular stuff in taking care of knives. Perhaps a treatment of some oil protectant like militec, weaponshield, tuf-glide /tuf cloth, etc - but same goes for any knife really. I use them regardless of how stain resistant they are, just force of habit while I, for most, a once of month maintenance [depending on use]
 
Got to handle this bad boy last night with Thomas and Jim, who designed it. This new ZT is so incredible, you guys think the pics are amazing, wait til you see and feel this thing in person! Wicked:thumbup:

The clip, the back spacer, and the lockbar all come together really nicely. It's light as a feather, the blade shape is really something, love the composite damascus. Very very cool knife all around!
 
Thanks for the heads up.

Thanks for the input! :thumbup: No pics?
 
I played with this knife for quite a bit today. Wow it's light and the "bonding" was seamless. I would have bought this and the 560 in a heartbeat today. I plan to go back tomorrow to see both knives again. Root'n for this one to be out in a reasonable amount of time. Super nice
 
Good to hear - thanks ;)
