As mentioned in this thread:
http://www.bladeforums.com/forums/showthread.php?s=&threadid=215822I I have found that all the satin finish knives I own form small dots of rust on the blades no matter what I do to protect them.:mad: The knives this has happened to are my BM 9000 SBT, My Kershaw Chive, My Kershaw Scallion, And a gerber chamelion. I was wondering if any of you have had the same problem with satin finished blades. I have tryed coating the blades with miltec. I also store them in a box with silica gell packets to absorb water from the air. I will never buy another SF knife ever, if there is another choice.
 
I feel bad that youve had trouble with satin finish blades, but unfortunatly these things happen. You mentioned you store yor knives in a box with silica gel packets, this may be part of the problem. First the silica gel ( dessicant ) needs to be activated ( dried out itself) if its to do any good, and be stored in an airtight container. If it is not stored in an airtight container, it will become saturated, and consequently will do no good in protecting anything. Second, provided that the dessicant is activated, the knives really should be stored in an airtight container. This is so the moiusture that may be present is absorbed by dessicant, and no more can get in. I store all my knives either open (folders) or in there sheaths, some I put a coat of CLP on, others I dont. Most of my knives are in my basement, Ive never had a problem with stored knives deveopling rust unless someone with salt on their hands handles them and the blade isnt wiped down. Good luck with this, hope you can figure something out. -- Charles
 
My Kershaw Chive and Scallion have bead-blasted, not satin finish. Bead blast is a bit more prone to developing rust because the microscopic pitting from the bead blasting in the blade traps moisture if not wiped carefully. I find satin finish blades can rust too, but are generally easier to keep wiped clean.

Where did the rust form on your Benchmade? You listed it as an SBT model, doesn't that designate that it's covered with the BT2 black coating with serrations?

I often store my knives without coating them at all, but my environment is probably different to yours. A few I store with a bit of Tuf-Cloth and had no problems.

A bit of Flitz every now and then can usually solve this problem. My bead blasted knives all get a good 'Flitzing' at least 3 times a year (these are the ones that aren't in use). The ones that I use often get cleaned and polished once every 2 to 3 weeks.
 
I ordered the SBT from PVK around 4 years ago. If I remember right the pic on PVK showed the BT2 version. When the knife arrived I was a little dissapointed that it was SF but I figured it wasn't that big a deal. The knife only rusted on the blade itself. As far as the Chive and Scallion, I thought it was SF but if they are Bead Blast I apologize for my error. Now you guys got me curios about my BM. Does anyone else have an SBT with out the BT2?
 
Will22: Wait until you try certain bead blasting, like CRKT's bead blasting :p
A AUS6 knife can rust because of the finish.
 
My Chinook developed a tad bit of surface rust in just a few days time. Kind of surprised me since I thought the CPM440V would be a bit more rust resistant. And, it came right off with a little Semichrome. But, on a using knife, other than the appearence, is the rust really a problem? I can't see the rust degrading the steel in any way. If your knives in storage are rusting...then somethings going on. I have blue pistols that live in my gun vault with nothing more than a wipe down of a decent oil once or twice a year that have never rusted.

Here in Texas, sweat and summer just go together. Most all of my stainless pistol that I carry concealed get occasional rust, particularly under the grips, but, I never really worried about it, between all the little bumps and scratches they get just by being carried around, I just take the grips off every few months, hit the rust with a bronze brush and a good oil and not worry about it, much like I have done with my "stainless" knives for years.

I really don't mind if my tools get a little character from being used.
 
If your BM gets to craped up just have Bm put on a new one! I didn't even know this was an option myself until I asked. I was supprised it was only 30 bucks every few years that's not so bad.
 
The finish has little to do with the blade rusting. It is the type of steel that the blade is made from that is the problem. Certain types of steels are more prone to rust. That said there are only two advantages to having a satin finish blade. 1: it looks cooler (in my opinion). 2: if you are using the knife for any sort of food prep, it may be safer.
If you are using the knife for food prep use mineral oil to preserve the blade. It is tasteless and oderless and does a fantastic job of preventing corrosion.
 
I get little rust spots on one of my satin finished fixed blades all the time. I wipe it down and oil it with Break Free 2 or 3 times a day and it doesn't help. I've even used Cosmoline with little effect! Maybe it's just because it's O1, who knows. About once a month, if it's more than a few spots I lightly refinish it and buff it out with 0000 steel wool.
