    Im looking for a PARA 3 to carry but will also be using it on the boat. Wondering which options are the most corrosion resistant.

    s110v. Be generous with oil on the Pivot.

    Spyderco just needs to put some black & yellow striped G-10 on the PM3 along with some LC200N steel to make a Caribbean Junior...
    Other than that & H1, it looks like S110V is the best, according to this Spyderco thread from 4-16-2017:


    Re: Corrosion Resistance Ranking of Stainless Steels

    My subjective rankings from another post a little while ago:
    10: H1, LC200N (based on Surfingringo's report), glass. These things can't rust. Go ahead and try.
    8: S110V (really stainless, only managed to get rust spots by leaving joint compound on it to dry, and even then it wiped right off)
    7: S90V/CTS-20CP, CTS-XHP, CTS-204P/CPM 20CV/M390
    6: VG-10, S30V/S35VN, 440C, Elmax, CTS-B70P, GIN-1, 440A, 12C27, 154CM
    5: AUS-8, Cruwear, ZDP-189
    4: D2, PSF27, Sleipner
    3: M4, 1095, 5160
    2: Super Blue (rusts in humid weather if not protected)
    1: My car (results possibly skewed by New England's liberal use of super-salts on the roads [​IMG] )

    I may split the 7's and put the M390 variants above the S90V variants based on super scientific sweat testing, but I think it's largely splitting hairs. Other than that, these are still my opinions/absolute truths. [​IMG]

    I would use the lightweight.
    Cheapest Para so far.
    Or a S30V. Easy to sharpen.
    Hopefully we get a Salt version this or next year.

    Why not get a Salt series and not ever have to worry?

    S35VN has been the most corrosion resistant steel I’ve come across other than H1. (I’ve not used lc200n) I have snorkeled in the Caribbean for literally hundreds of hours with a Native lightweight in S35VN. Never took the knife apart until a year later with zero signs of rust inside. I just gave it a freshwater rinse after a trip and scraped any small rust spots off with a stick. No problems. So I would choose that knife over a Para 3. I would, however, try out a Para 3 Lightweight snorkeling. The BD1N is reported to be extremely corrosion resistant.

    My P3LW has actually shown pretty poor corrosion resistance.

    You may want to just get a model that's full corrosion resistant. Even if you go with s110v the hardware is not corrosion resistant.

    m390/20cv/204p are hard to find and expensive for no reason.

    H1 would be idea. But also is lc200n in the salt line or the Spydiechef but that's also hard to find currently iirc.

    Otherwise just use proper maintenance and oil and you'll be fine.

    Hi Wave,

    As suggested, if you are going to be on a boat in a salt water environment, I would get a Salt.

    How far out are we on a Para 3 Salt?

    Doubtful, I think the closest we are gonna see will be S110V

    I doubt that'll be a thing. A para3 lightweight salt maybe. Less bits to replace with H1 or lc200n?

    I'm in saltwater at least 3 times a week.

    Get something in H1 or LC200N.

    My 52100 PM2 stays in the car.

    The Atlantic Salt is in the surf with me all the time. Never rinsed. No rust.

    It has shown rust spotting every time I have gotten it wet and let it air dry, similar to what D2 does. On the grinds as well as the edge. I still like the steel, it sharpens and holds an edge well, but to call it “highly stainless” is definitely not accurate.

    Does it stain or just clean right off

    It stains, not terrible and will come off with a vigorous rub with isopropyl alcohol, not pitting but definitely brown staining.

    I’m not trying to criticize BD1N at all, I think it’s a very good steel and like it a lot, but I do want to correct (what I see as) bad info out there portraying BD1N as this side of LC200 as far as corrosion resistance, it’s just not true.
