Spyderco Manix rust resistance...

I work at a fish store, the humidity is very close to 100%. Any bead blasted knife gets rust spots within an hour. So I usually stick with coated blades. I can't oil coat the blade because often I have to put the knife in fish water and the lube is toxic. So what I'm getting at is, I have been looking at the spyderco manix. I know the blade is satin finished and that closes the pores, but the steel is S30V which is not very rust proof. Is this knfe gonna pass the gauntlet? I'd hate to spend that much money on that knife and have to polish the rust off 5 times a week. Any help appreciated...

Flitz it up once in a while and it should be fine.

I can't recall having any rust problems with S30V, although the humidity that I'm in is nowhere near 100%.
 
I haven't tested the Manix personally, but I have a few blades in s30v, and I live in socal near the beach, AND we've had quite a rainy season this year. Long story short I've had Zero problems with s30v as far as corrosion resistance goes, in a climate where I've had trouble with aus8 staying rust free. Good choice on the manix btw, but if you can try it out in person before buying it's a good idea.
 
Yes, those are advertised as being very rust resistant. If you like the Manix, save up for that AND the salt knife. Carry your Manix with a good coating of Mad Dog XF-7 weapons lube and also have the salt on you for using all day at work.
 
Dude, sounds like you need some Talonite. Camillus makes the EDC in Talonite, for just a little bit more than the Manix costs. Then you would never have to worry about rust. S30V should be ok, just take care of it.
 
TiNi coating as on Boa ;) should be OK. Higher Carbon content take away Chromium - makes chromium-carbides and there is less left to make chromium oxide protection layer, so even it has enough Cr to be declared as stainless it is not corrosion resistant as 420 with smaller C content. There is H2 steel which is wery corrosion resistant.

Thanks, Vassili.
 
TKD, I think you should be looking into knifes with an H-1 blade. That's what they were made for!
 
H-1 seems the way to go. They are designed to be in and around water all the time with little to no maintenance on the users part. I do not live or work in your conditions so I don't know how my s30v would hold up, but mine holds up fine in Chicago weather.
 
Uhm how about the Spyderco Salt or Atlantic or Pacific, all of these were made to resist rust and be used in such environments.... :confused: :D

Exposure to salt water or just fresh?

I'll seriously consider the H1 steel knives. But to answer the last guy, it's just fresh water at this store...
 
I'll start a soak tonight in fresh water and let you know how it effects the sharpness and what kind of corrosion can be expected on the flats.

I have used my Manix around Salt water and in a very humid environment (IWB in the back of my shorts) The blade rusts no more than any other stainless and is easy to keep free of rust spots by wiping it clean. The rear spacer, on the other hand, has some serious ugly looking rust spots in there that are hard to reach with a wire brush. Not a huge issue if you are into maintence but makes the Manix fall well short of earning a maintenence free tag IMHO.
 
Way to go, Cliff! (both thumbs up, missing the appropriate smiley for it though) :cool:
 
The Manix, Vagabond (AUS-8A), and Agent (D2), were wrapped with 12 pieces of single ply toilet paper, folded in half width wise and soaked with tap water, from a well. They were left soak for 10 hours.

The Vagabond and Manix showed no evidence of corrosion, by eye, under 10x mag and the edges were still shaving sharp. The Agent showed no corrosion visually either, however the edge sharpness was significantly reduced.

From what i heard the H1 steel did not show any corrosion after a 24 hour salt water spray test! There is nothing more you can do to get steel rusting then spraying it with a fine mist of salt water.

I would go for the knives i already mentioned. The FRN handles will give better purchase with slippery hands then the G10, and the Manix is just a too good knife to use as a fish cleaner.

:)
 
The point of the above wasn't that the corrosion resistance of S30V is the same as H1, simply that fresh water usually isn't a problem for high end stainless. Salt water exposure however is another matter. It usually pits those materials badly, I have not done a soak on S30V yet however.

I live and work in a very high humidity enviroment. I have owned and EDC'd several s30v knives and I can tell you that they will most definitely show rust spots after just a day or two. Daily upkeep will be required. Knives carried include the Spyderco Military and the Wegner Pro Hunter.
I have been carrying a Pacific Salt w/ H1 steel for the last eight months and have had zero...not one spot of rust...that also being without any daily maintenance. I wipe it down every week or so or when it gets especially dirty...no oil or lube involved...just a clean cloth or rag. H1 is awesome!
