looking for folders in "tough" steels, any suggestions?

Ankerson said:
Ah, no..... Sorry dude....

Sharpness is the actual measurement of the apex measured in nano-meters and I know I can get them to the same point.

I use S90V pretty much everyday and it's thin at .006" behind the edge, haven't seen any chipping issues even cutting through bone.

Did you use your nanometer measuring stick?:) I've got a 300 power microscope I look at edges with and I can tell you that you are wrong.

Yea ok. I've got a s90v v blade that chipped within the first week of using it and I've got a 1095 blade i've used for 30 years doing the same exact thing and it is yet to chip. You do the math.

Sharpen much?

Everything I use in the kitchen normally is .006" behind the edge, that's S90V, S35VN, S110V, S125V, all fixed blades.

Not even getting into the normal knives at more normal thickness like in folders that I carry.

Not mentioning all the ones I have tested over the years pushing them through knots and other assorted things.

I have a certified sharpness tester. ;)

The only thing more accurate than that would be an electron microscope.

Yea the 810 I bought is coated m4, I would like to see coated or laminated tool steel blade folders explored a little more. Get the properties of the tool steel and protect it with a lamination or coating.

Laminated steels like Falkniven uses would be a good compromise of strength and corrosion resistance.

Yep, I've seen your certified sharpness tester, the merit of push cutting a thread is up for debate in my opinion. If you look at the 2 edges in profile the grain structure of 1095 is finer than s90v. And I think all them little carbides fracture out of s90v at that level the first time you use it. So you end up with a good working edge, but it is no longer screaming sharp. I'm going fishing now so I will agree to disagree. You have a good day:)

Not from my testing. ;)

Did a direct comparison between S110V and Superblue.

There was no measurable difference in high level sharpness in use.

I certainly don't need the toughness of 3V in a folder nor do I own any folders constructed of the high-toughness alloys you mentioned. I have some fixed-blades made out of them, though.

I personally don't need or want a folder in those high toughness steels either but I'm surprised that they aren't used by any of the companies that make the big hard use tactical type folders like Emerson, ZT, Strider...etc
 
kraftzion said:
I'm back, got rained out. I have no experience with either one of those steel so I wouldn't know. The only steels I've used and abused long enough to know their relative strengths and weaknesses are 1095 ans s90v.

I tested the 2 extremes of the spectrum to see if there would be any differences in a very narrow scope of high sharpness level.

There wasn't based on my testing.

Now things would change later in the dullness curve, I was only testing high level sharpness.

What was your opinion of super blue? it is 1 of the steels I'm interested in.

I think it's a good steel, tested it before and it does hold an edge pretty well, shouldn't be hard to sharpen for most people.

It's a nice premium Japanese steel.

Thanks, I know spyderco made a a folder in it do you know of any others?

Spyderco has some available I believe.

The rest would be Customs I think, not aware of anyone else producing production folders blades in Superblue.
