To me a blade with a patina is more beautiful than a SS blade, but in use I don't discriminate.
I have D2, M4, Rex45 and Maxamet blades with nice patinas and never any rust.
By using them on acidic food and never applying any protection (eg petroleum jelly) I encourage patina (but I never force it). As a result, they are not rusting.
I also pocket or IWB carry them occasionally.
Maybe it also matters that I am not storing them locked away in a safe, a drawer, or a Peli case, but on a shelf with normal air circulation?

Re: Tool Steel Conundrum
I guess I’m lucky in that I live in a very humid state and I sweat, but I’ve only ever had some spotting on M4. Even my 1095 traditionals can be carried without rusting. I just use a bit of food grade mineral oil on them, very occasionally.
This thread helps point out how important the creation of Magnacut is to the cutlery industry. Tool steel performance with excellent corrosion resistance.

Re: Tool Steel Conundrum
Magnacut is great, but I still think laminated PM tool steels (like HAP-40) some advantages over Magnacut. IMO, it is nice to be able to easily grind down the primary bevels to thin out the blade after the knife has been heat treated. The downside is that the soft stainless cladding is easier to scratch. However, the scratches are easier to remove.
Re: Tool Steel Conundrum
Earlier today I was dismayed to discover a ton of rust spots on my m4 Manix. Don’t know what I cut and didn’t clean off but it sure made its presence known.
Cut some cardboard with it, it performed well but I discovered I must have left a tiiiiiny burr intact last time I sharpened it.
Did a quick touch up, went to check sharpness, **** near shaved my whole leg by accident. Silky smooth.
Knife is still covered in rust spots.
I guess my point is…. So what?

Re: Tool Steel Conundrum
I am very much looking forward to Magnacut, and can’t wait to get a Spyderco in one. Until then I’ll just keep trying to keep my knives oiled and embrace the rust spots!

Re: Tool Steel Conundrum
i definitely favor stainless over tool steels. if i want a carbon steel blade, i'll get a $15 mora. i don't want to worry about my $100+ knives rusting.
keep your knife sharp and your focus sharper.

Re: Tool Steel Conundrum
I had been carrying an Advocate for around a year. It uses CPM-M4. A little discoloration here and there but no rust. I put it in a drawer for a month and now it is getting some surface rust on it. I guess I will take a wire wheel to it and get rid of the rust.
I think I am in the minority, but I don’t like to use lubricants on my knives. Especially users. The lube seems to attract dirt and dust. I usually take my knives apart and clean them. In a pinch, if I get a folder wet, or dirt and grime are interfering with the action, I will drench it with WD40 and shake it dry until I get a chance to take it apart. The WD is more about cleaning and moisture displacement than lubrication.

When you're hiking in the SE U.S. ... rust proof is highly desirable ... SE SpyderHawk is my constant companion IWB when trail running. Hasn't let me down, not once.

Re: Tool Steel Conundrum
Half a summer’s day on the coastline and I’ll get red rust on M4. Still a fan of tool steels!
