Bullet proof steel that keeps and edge forever

Survive! Knives has videos of his 3v knives left out for a month and a year and it was cleaned off easy after a month with no real patina.

That's interesting. My understanding is there isn't enough chromium in it to make a big difference. I had heard that it tended not to surface rust as easily but would pit. An awesome steel though.
 
Buy the knife you like and be happy! Just be sure to wipe the blade before you put it away. Invest in a Tuff Cloth and no more troubles.
 
I don't know why it struck me as so funny, but I almost blew my drinking water out my nose at the celibate monk's father comment. :D
 
Beta C titanium strike plate or
ATI 425 titanium alloy, with carbidized edge.
If you understand these material, I won't have to explain why...
 
CPM-3V is my overall favorite blade steel. I would happily work with INFI if I could get my hands on barstock.

You can't always simply look at chrome content by itself to determine how well an alloy will resist corrosion; all the chemistry works together. 3V's moderate amount of carbon (.8%) is mostly tied up with the iron and molybdenum and vanadium carbides, leaving much of the 7.5% chromium free to add stain-resistance. It's also quite fine-grained, which is good for pretty much every aspect of a blade from toughness to getting nice crisp edges to just looking good with a fine finish.

When properly HT'd, 3V has similar "semi-stainless" properties as D2 and also similar wear-resistance... but it's much, much tougher. That extra toughness not only helps the whole blade resist breakage, but increases overall edge-retention by preventing chip-out on thin edges.

If a real "stainless" steel is required, Elmax and CTS-XHP are the only two I have personal experience with that approach the remarkable balance of toughness and edge-holding exhibited by 3V. Other makers report very good performance from M390 in heavy-duty knives.

I've been waiting years for someone to put a 1095 (or any other simple carbon steel) blade against one of mine in 3V for edge-holding, rough use, abuse, and destruction testing. No takers so far. ;)

That doesn't mean 1095 is "bad", of course... in all honestly for most users it's a perfectly capable steel and certainly tough enough for almost any sane use. It's also easy to sharpen. But there are better steels widely available.

If you truly want a long lasting edge, get a knife with a blade made of diamond.

Here ya go. The Swiss Army laser knife. It never needs sharpening and won't rust.

Yeh, but how do you deploy it? Talk about a nail breaker!!!

I was thinking about that magical steel call unobtainium.


Here's my solution.

DMT Credit Card sharpener. Provides fast touch up of m

Bulletproof: SOG Tigershark comes to my mind.
If you do a search; you'll find pictures.

My 1095 comment was mostly to see what kind of reaction it would get :D
I do like me some properly HT 1095. I guess I'm showing my age because most of these young whipper snappers have probably never heard of it.

I've never thought of it as having superior edge retention or toughness James. I'm slowly opening my eyes and trying new things.
My first experience with more modern steel was my first Benchmades many years ago in 440C and ATS-34. Both were used the hardest of any knives I have owned, and they served me very well.
Over the past couple years I have been using S30V, D2, and more recently Benchmades M390. So far I have yet to notice anything magical, but I haven't used the M390 enough yet, to give an honest opinion.
 
has anyone ever really broken a well made knife that was designed for relatively hard use? I mean aside from "torture testing" you can beat on almost any decent steel and it'll take more than what you would expect... I had beat the piss out of one of my own knives to do some testing and it took it like a champ. a few guys watching were throwing comments around and one guy (knowing a fair bit about knives) asked me what kind of steel it was, and when i said "just good ole 440c" it took some convincing to get him to believe it would take all of that.
 
Keep an edge forever? Well, clearly you want one with a blade made from the highest grade of unobtainium.

The old stories say there are some of these around — so long as you don't really want to possess it.

There's Excalibur, for example. But that comes with a tiresome day job — all that virtue, all day, every day — and you'll need infinite patience for endless meetings around this table with no corners and a dozen grumpy guys....

And I hear tell a guy named Siegfried of some German clan was able to roughly forge a blade shape, but no has yet figured out how to put an edge on it, let along retrieve it out of that river with all those girls swimming around.

Well, sonny — a Quest awaits you.
