Spyderco super steels (m390, m4) ur daily users or safe-squatters?

So let me ask this to the metal experts in here?
Is there any practical reason to NOT own a premium steel?
I'll define the term to include steels like; but not limited to:
S110
S90v
M390
K390
M4

I think it comes down to sharpening. Some people don't care if their knife stays sharp that long as they can touch it up a lesser steel frequently and easily. But I like that these steels will cut all day long and with the right tools can easily be touched up.

Really?

And I want to add all my sprints are users

Bento box m390 pm2
Rex 45 shaman
20cv military
S90v ti/ carbon fiber military

(I have more but it's too late to think lol)

All have scratched blades and obvious signs of use, and they're great!

Looks like most sites sold out since last week. I found one site that still has them, so there may be more out there.

Availability can be an issue, some of these steels are harder to get. They will definitely cost more, maybe a little more, maybe a lot more. Depending on your equipment and your ability they might be harder to sharpen than the standard steels. From your list K390 and M4 are carbon steels that will corrode more readily than the other 3. S110V and S90V may tend to chip more than the lesser stainless steels.

But back to the original question- I have a batch of knives that I rotate through for daily carry and a few others that I use in my workshop. Of those knives I have S110V, M4, Rex45 and K390. I carry and use all of them. I won' t say that I can tell any difference between them other than the corrosion part. If I did manage to do something particularly difficult I hope that the carbon steels would resist damage more than the S110V so I'm careful what I do with it.

K390 and M4 aren't "carbon steels." They're non-stainless alloys. Carbon steel is an alloy of iron and carbon, like 1080, 1084, 1095, etc. Technical difference but I think it's important.
 
A super steel blade won't cut you any deeper than any other blade that is equally sharp.
But it will cut you more often: before it needs some passes over your ztones.
