Non-ferrous

I've got a completely non-ferrous blade, it's a Stellite kiridashi made by J. McGowan. The metal is a cobalt based alloy that a few makers have played with, and it's a one-piece small fixed blade.

Add a kydex sheath for pocket carry and I'm good to go. It's my around the water or exercizing knife.
 
Hey Jarod, I'm sure your H 1 is great stuff, but heads up my friend titanium with all of its three variants alpha, beta and alpha beta DO NOT RUST, when one shop that makes Titanium knives cleans the blades before fininshing the product they soak them in hydrochloric acid, they do this to clean them, Ti has an invisible layer of molecules that even when damaged reforms almost instantly and protects the material. I've had mine muddy, bloody, wet with salt and fresh water, caked with sand and everything else and you know whats funny about it the nastier I get the knife the better the thing continues to look. Also spyderco makes inexpensive knives notice I did not say cheap, but there inexpensive I'll put the quality of fit and finish and overall quality of materials and workmanship againest anything H1 spyderco anyday. sorry they just can't hold to what Mission makes plain and simple if they did then the military would be buying from spyderco and not mission, plain and simple.
 
Corrosion resistance and weight are the only areas where ti beats steel. You also got to remember that steel rust but non ferrous items corrode. I have seen copper, brass, bronze, galvanized steel, zinc, silver, gold, lead, nickle, and several other metals corrode. I am sure if i had time to play with ti it would have some corrosion properties.
 
Guys, titanium doesn't corrode, thats why you get metal put into a human body via an accident guess what its titanium why because it doesn't rust or corrode, its also inert. They design parts on high end machines which cannot be replaced i.e. satelites, with what material, humnnn lets see its titanium. I'll agree its not the best blade material but hands down the stuff doesn't rust and its near imposssible to break, chip, etc. so thats what gets my money.
 
Mike if you aren't chipping titanium you won't chip anything, titanium is harder than steel and far more brittle, in most cases titanium will snap where steel will bend. I hate that it is some super material, sure its great and very non reactive but it's not super metal.

I believe satellites use Aluminum rather than Ti.
My company makes aerospace components and when we use Ti, it is usually for it's higer heat resistance. If we need high strength we use...steel.

Actually, Ti, alike Aluminium, corrodes almost instantly, creating inert layer of oxide on surface which gives the material corrosion resistance.

Titanium isn't harder than steel :eek: There are many grades of Ti, but none can match (hardenable) steel.
Most important asset of Ti is it's lightness.

Here is useful link
 
I'm not sure why it hasn't been mentioned yet, but...

Why not just check your knife in with your luggage? It'll be there as soon as you get off the plane and you'll be peanut capable for your trip to wherever.

It's always worked for me.
 
Actually scratch that, generally Ti is stiffer than steel.

It's been awhile since I read about Ti, maybe I was thinking unhardened steel or something, iono.

All so far practically used Ti alloys have a smaller modulus of elasticity than steel.

Jarod, H1 will rust maybe not eventually but at some point it will rust its steel which means it has iron in it thus making it a ferrrous metal. It may take longer for the oxidation process to start but the eventually its going to rust....I'll put any Mission product up againest anything spyderco will has, is are will EVER put its name on, period.

If you can somehow manage to get a Spyderco Salt to rust or corrode in your lifetime, I think many of us would like to see it...

Meanwhile, the Salt owners will be busy enjoying the vastly superior edge characteristics of H1, the variety of blade shapes and sizes available, and the affordable prices, rather than trying to blindly bash another manufacturer's products.

Padawan, it is possible to get metals like gold and platinum rust. What makes you believe it's impossible with H-1? (although confronting chemicals is certainly not something you encounter in daily use, it doesn't mean that H-1 can't be brought to corroded state).

But I agree it's much better option than Ti for a knife blade.

No, it isn't, unless they contain traces of iron or steel.

I did not use the word impossible, but to date, I have not read of a single instance in which an H-1 blade has been made to rust, even when an individual tried his best to do so. My point was that over the course of a lifetime, unless you're routinely placing the knife into contact with some caustic or corrosive substance, you simply will not get a Salt to rust. Using a Salt in fresh or salt water, mud, blood, sand, sweat, humidity, etc., just will not affect it.

I was not trying to state that H-1 is the magic ideal blade steel. Rather, I was pointing out that individuals stating that they only purchase titanium knives because any other knife will rust under their usage just do not have a valid argument.

No but it will corrode.
 
I believe at some point Mission made a folder with a Ti blade and handle. I am not sure about screws/washers/spacers though.

It is certainly possible for H1 to rust, since it contains iron. But, in all the tests I have seen, it hasn't. All the tests I have seen have shied away from use of strong acids and other toxic substances. But the vast majority of people do not expose their knives to strong/concentrated acids on a usual basis.

I also do not doubt that under certain circumstances that Ti will corrode. But again, most knives are rarely, if ever, subjected to these circumstances.
