SAK Corrosion Test #1....

Tonight I just started a corrosion test on two Victorinox SAK's...

subject #1 is one of my "Frankenstiened" Signature Lites, it's the one i pulled the scales off of and swapped them with my Minichamp, the Minichamp now has the Ruby scales that were previously on the Signature Lite, and the SL has the MC's plain red Celidor scales

I also put in one of my hacked Bantams, I rounded off the tip and droned the blade, to make a "My First Victorinox" for my nephew once he shows enough responsibility to own a knife, for now, it's the second knife in my 2 knife corrosion test

the testing chamber is a 2.5 gallon glass aquarium with glass top, it's filled with approx. 40 Oz of seawater from York Harbor Beach, Maine, and there's a "bubblewall" spraybar creating a highly corrosive saltwater spray

this is the same test chamber I used in my Spyderco Pacific Salt and Salt 1 tests, neither Salt series showed any sign of corrosion, however other knives in with the Pacific didn't fare so well....

a cheapo Sheffield Hawkbill from Home Despot showed signs of corrosion in ONE HOUR, and was out of the running at 6 hours, a cheapo butterfly knife lasted 24 hours before failing....

it's a nasty, nasty environment for *any* knife (except perhaps for H-1 steel based knives....), it'll be interesting to see how long it takes before rust appears....

test started at 11:00 PM EST....
 
This will be fun to watch. I bet they'll put up a good fight though, SAK steel has some superb corrosion resistence in my experience.
 
12:45 AM; we have our first signs of failure....

the Signature Lite Scissors show signs of corrosion around the pivot, the scissors were fully submerged in the salt water, no rust on the blades in the salt spray, yet

the Bantam is still unaffected
 
The previous failure post on the SL was in error, what i thought was "rust" was just compressed pocket crud

However....

the Bantam has shown it's first rust spot as of 9:00 AM EST....

the rust spot was on the blade that was in the salt spray, the Combo Tool which is *submerged* in the same salt water has shown *no* signs of rust yet
 
I would like to see a Wenger vrs Victorinox salt water showdown using two similar models.

5:50 PM EST update;

No further growth of rust spot on the main blade of the Bantam, *however*, there was some whitish "fuzz" on the frame around the Combo tool, i believe that's aluminum corrosion, Combo tool still unaffected

SL has *definite* rust on the scissors now, around the pivot, no rust on blade or file though
 
The pivots are known to be a quickly rusting part of the scissors component. I'm kind of curious as to why they make them that way. Maybe they use a different steel for added durability to protect it from extensive wear? Hrmm....
 
Vivi,

From what I was told after my test is that; when you have different metals in a solution, one tends to act as a cathode and the other as an anode. Once the anode is gone, another part of the knife should act as the new anode and start to oxidize at a increased pace. Whether that would be the liners, pins or whatever, I dunno.
