Just How Rust Resistant Do You Find Vg10?

[MANIXWORLD]

I have to honestly say that VG10 is one of the best allround bladesteels at a affordable price on the market today.
Getting back to the topic,ive actualy had zero corrosion problems with this steel sofar.
even after saltwater exposure with minimal maintenance after, and usage of VG10 blades to cut lemons,no rust problems,ive found.
VG10 does tend to get stained otherwise with small grey looking spots,which doesn't look like rust,but it usualy gets wiped away easily with a soft cloth and a little metal polish,but i have never noticed any brown rust spotting as such on my VG10 blades,even some of my much older VG10 blade Spydies,nothing.
I feel that VG10 is second to H1,with NO corrosion issues,whatsoever,but not exactly equal to H1 WRT corrosion resistance.

I seem to recall a few small dark spots on an vg10 impala after a hunting trip, but they wiped off easily.

I've had some surface rust after not missing some spots when rinsing off, but nothing serious. Wiped right off, left no pitting at all. I love vg-10. :)

My VG-10 folders have remained completely rust free, but my Yang kitchen knife rusts like crazy.
If I wash it in the sink and put it to one side without drying it, brown rust spots develop in just a few hours.

That's interesting...I've left my Yang lying around with water on it, and no rust spots have occurred. Wonder what would cause the difference?

High concentration chloride in tapwater-leading to corrosion?maybe..

In case you do not wish to return the yang for an exchange:

If that's surface-layer only (say from sawing+grinding immediately after a run of non-stainless steel *), did you try to go over the surface with say a king 1000 waterstone for a bit to remove just a bit of the top layer (or dull the edge and use a felt wheel on the sides with due care)?

Would this stop the rust?

* even so, this would still be a QS issue, so returning it is probably the better way to deal with it [after maybe taking a peek in a small area of the surface :) ]

I don't feel that I need to return the knife. I just dry it after washing.

my Yang also rust a little :o

In my experience, VG-10 develops a bit of a patina, but doesn't rust easily at all. A friend's Endura 4 developed some light rust spots from not being touched for a few months (somewhere in his home).

Overall, VG-10 is one of my very favorite blade alloys. :)

I've not had VG-10 rust ever on any of my knives. Not even get spots or anything. I used a Native III outside a TON last year doing outside work around the house and it got sweat on it quite a bit. Never rusted.

Actually I think that all of the steels that Spyderco uses have been like this. I don't have problems with rust on any Spyderco blade.

the only exception i've heard is ATS55,that's why spyderco switched from ATS55 to VG10

I work where testing is done for on steels in environmental chambers very high tech . If you would like I can test and send back any steel you are curious about with specs . MG2

That would be cool--independent testing using your chambers at work. I'd be really interested to hear the results of that.

Not exactly;

Hitachi developed ATS-55 and offered it to us on an exclusive basis. Their claim was that it was equal to their own ATS-34. We tested ATS-55 at the same time we tested VG-10.

The ATS-55 was introduced on the Goddard lite weight, the VG-10 was tested on the Moran. After several years of testing, we decided the VG-10 was closer to our requirements and we adopted the VG-10 and dropped the ATS-55. It was hardly a bargain steel and significantly outperformed AUS-8 in all but corrosion resistance.

The above was quoted by sal in another forum that I will not link to as it is in response to a troll. It is slightly out of context, but does contain the important elements of ATS-55 and VG-10, that is they were near simultaneously introduced but VG-10 won out overall.

Only VG-10 knife I've ever managed to induce rust on was the canvas micarta Stretch that STR built for me. His opinion was that the combination of titanium liners, phosphor bronze washers, steel blade, when coupled with my habit of using the knife for food prep, rinsing it off, shaking it dry, and sticking it back in my pocket, may have contributed to that. During the rebuilt to Lignum Vitae, he changed the washers to plastic. Have been using it about a year now, with no signs of the rust returning, so electrolyis may very well have been the culprit.

Have had cases of both the grey spots and of a multi-color discoloration that reminds me of color case hardening. But have had the same on other steels as well, especially on knives I use in the kitchen. I chalk the grey spots up to hard water leaving mineral deposits. The other is definitely a chemical or electro-chemical reaction. Both are harmless, in the sense that a blade so discolored can be left a year with no maintenance and the grey spots or colors will not get any bigger, darker, or feel rough to the touch the way rust or any other form of corrosion would.

I've had no corrosion or spotting issues at all on any of my VG10 blades... even the D3 that went to the ocean with me and was submerged several times that week to see how it would hold up.

I had put Militec on the blade before the trip and I rinsed the knife in fresh water each evening. More Militec when I got home after a week at the beach. No issues at all.

[RIOT]

ive never had one spyderco rust on me in the last 16 years not even a hint of rust and majority of all my knives ive used vigorously

[bladese97]

:spyder: :spyder: :cool: :spyder: :spyder: I had one surface rust issue with my D'allara/CE, but caefully removed it using a buffing wheel at work :eek: Ya...Wasn't very smart, but I did it, and it didn't hurt the Blade, or the Spyderbug(where the rust spots were) :eek: :D

I am a kayaking instructor and I recently replaced my knife with a Spyderco Assist Lightweight. My area of operations is equatorial seawater. My normal procedure is to thoroughly rinse all my gear in freshwater and hang to dry. I find the serrated edge very sharp and I like the lack of a sharp tip.

I note the comments on Spyderco's VG-10 steel and how it does not rust, but rather just shows some staining. Unfortunately, my experience is not in line with these comments.

I am thinking HARD about an H-1 steel knife. But I'm not sure after the reassuring comments about VG-10.

I attach some photos hoping I can get some advice.

Thanks,

Colin.
