so, with all the recent threads about rust, i figured i would put some of my spydies to the test.

1. atlantic salt: well, we all already know what the outcome of this will be. more of a control than to actually test the h1.

2. s90v military: should be pretty resistant, but we shall see.

3. d2 military: semi resistant? im really curious about this one.

4. vg10 smith: also should be pretty resistant.

solution is water mixed with saline solution. i have soft water, so wanted to speed up the corrosion. this is purely to satisfy any curiosity, i didn't measure the amount of water or saline, and will check periodically (read: when i remember). enjoy!


initial submersion. i put only the blades in the solution, i didn't want to have to worry about rust in the pivot areas or inside the scales.

after about 4 hours.

the d2 has a small spot of what appears to be corrosion near the edge.

Interesting experiment here. I hope your blades don't get effed up man. I'm interested in seeing how these stack up to eachother.
 
In my experience, D2 tends to pit rather than getting general surface rust. That spot could well end up being a hole in the edge. Good luck.
 
besides, if i really start to see some discoloration, ill take them out.

this will end sometime tomorrow regardless.

in my experience, D2 tends to pit and rust.

a spot nearer the choil is actually now a hole in the edge and surrounded by surface rust!

there are a few black spots on the blade and spine as well.

how long has it been??? anyway, photobucket aggravation, so pics will have to wait a few....




and vg10 and s90v have no signs of corrosion as of yet.
 
I've had my Spyderco Streetbeat (VG-10) pitting in me. So I don't doubt D2 will. It's more like a matter of time, and the fluid's components, but ebentually all but H-1 will rust.
 
I am definitely curious to see how the blade steels fare. I pretty much figure D2 to be a given first to rust out of that group, but I am a bit curious about the others. Hopefully, you won't have any real trouble cleaning that corrosion from the blades..

I try to take very good care of my knives as far as not leaving them wet for too long, etc, but one time I did lose my ATS-55 out on the farm for a month or two - I found it semisubmerged in the mud (not clay but probably a 1/3-1/2 clay to total mass loam mixture, the iron content of the clay being my point as it tends to not be so friendly), not a single mark. ATS-55 may not hold a fine edge quite as well as some steels, but for corrosion resistance, I have generally been very pleased. That said, I don't spend too much time around salt water, I intend to have an H-1 blade soon anyway, and I always like to clean my knives when I gunk them up.
 
the spots on the d2 are definitely pits. about 6 total, 2 on the actual edge.

probably because the saline sped up the corrosion process. since it corroded so quickly, i removed the other two last night before i went to sleep.

ill put them back in today.

be careful with your d2 blades!
 
I use the H-1 and VG-10 in a salt spray marine environment (coastal base, off shore anchor boat and semi-submersables).
Have been doing so for around 15 years with the VG-10 and about a year now with the H-1.
The VG-10 will maybe get a little surface indication in a day or two that you will be able to rub off with fresh water (spit) and a shop rag. The H-1 is likely still laughing.
 
Mark---Thanks for taking the time to do the test. Interesting.
I just ordered a D2 P-Mil. I'll make sure I keep the blade lightly oiled.
It is a good practice to keep blades oiled, imo.
