M390 vs S110V?

[gglotz83]

Hi everyone,

I'm looking for some information on the differences between m390 and s110v. Most notably, differences in edge retention and toughness. Thanks!

Generally
CPM 110v will have greater edge retention
M390 might have an advantage in toughness.

There are other factors that influence this that are actually more important.

Geometry
Purpose/use
Heat treatment
Hardness
Manufacturer

Discussion without these other variables makes the whole conversation moot.

Good luck.

I would pick M390 over S110V because it finished better and sharpen more easier.

Edge holding is subjective. Each physical attributes also have its role when it come to edge durability... hardness, toughness, wear resistance to the more complex subject like grain structure or carbide size etc.
Actually all of this are depending on the heat treatment... even two blade made from same steel at the same HRC hardness but dissimilar HT procedure can be so much different.

There are also many others variable like: what material to cut and how it was cut? ... slicing, chopping or push cutting? etc.
Geometry and edge finished also play very important role... some steel are has advantage at holding wide angle obtuse edge (most high wear steel) but suck with low angle acute edge...

Toughness for what? Fixed Blade or folder?

Are you going to be chopping bricks or cutting stuff?

That said most would never be able to actually tell the difference toughness wise between them.

Edge retention, there can be a rather large difference between them with S110V in general holding an edge much longer.

This is all in general and will depend a lot on the knives, use, and the end user, sharpening etc.

I guess with toughness I am mostly concerned with resistance to chipping.

I don't chop bricks, just cut normal things. This is for a folding knife.

Thanks.

I would say 110V is more suited for sustained cutting, where M390 is more balanced and trades some edge retention for structural integrity. 110V is the kind of steel I would choose for true EDC with a relatively thin grind (light cutting tasks are what I typically encounter) where M390 is what I would want for an all-purpose knife, more capable of handling some torsion and impact. A stray nail may put a chip in 110V where it's more likely to just sent or roll M390.

Not to hijack the thread, but how similar to M390 are its equivalents? Particularly 20CV and 204P?

They are the same, different name.

Each company has a different pm processing but you won't know the difference or care with the properly finished product.

This is why I've thought the hiked value of the 0562CFM390 and the 0620CFM390 was absolutely hilarious. They switched to 204P and people are -still- spending $300 on the M390 versions, which means people are paying a $60 premium over retail for DIFFERENT LETTERS ON THE BLADE.

I don't get it, but I guess I'm just not that variety of knife owner.

Haha right?!
