How do I get H1 to Rust?

Why do you want to try and make H-1 oxidize? Seems to me it passed the test.

Take care,

Amen!!! H1 appears to set a new standard in the stainless department. You could not want more rust resistance than this steel displays.
So the question now becomes: How does H1 compare with other martensitic stainless steels in durability and edge-holding? :eek:
 
I have to agree, at this point we have determined it's not affected by rust under normal and abnormal circumstances.
 
Update: Adding bleach/salt water mixture is starting to rust the clip at the edges where the finish is worn from pocket wear. Both ends of the pivot pin now rusting very heavily, even the part of the pivot inside the handles is rusting and the copper wire wrapped around the Spyder hole is turning green. Not a pretty sight - do not try this at home! :eek:

The H1 parts are still doing fine as is the lock pivot. :D

Next I am planning to do an edge holding comparison to my SpyderEdged VG10 Calypso Jr. (closest full serrated knife that I have to compare to the Pacific Salt).

Hi Frank. I think it's the washer, not the pivot. We got one back from Europe. Repeated deives to 50 meters. Showed some corrosion on the pivot. Analysis revealed it was the washer, the coating failed. So we changed the washer to another material.

The clip has already been changed to Titanium.

I think we've got it.

Sal, you are right - it’s the mainly washers that are rusting. I apologize for my mistake. :footinmou


The seawater/bleach solution is a pretty severe test. Everything held up fine for over a month in plain seawater/ salt air. It took the galvanic action of the copper wire wrapped around the Spyderhole and another extended soak to get the first bit of rust from the pivot washers and a soak in the bleach/seawater mixture (with the copper wire still in place) for heavy rusting of the washers and some rust on the edge of the clip where the finish had worn from pocket wear. With the new washers and titanium clip, I think I would be hard pressed to get any rust at all without using something that would destroy the FRN handles. :eek:

Frank, I've been reading your thread with great interest. I do have one question. Have any of your "tests" made any difference in the sharpness of the blade? *I'm just wondering and do not expect you to have done edge holding evaluations during this period.
Thanks, Walter
 
I have been checking the ability to shave periodically and there is no loss of sharpness that I have noticed. Keep in mind that I sharpened it on a SharpMaker before the test and given my sharpening skills (or lack thereof), even with the considerable assistance of the SharpMaker, I was not able to match the factory edge on this knife (it came with the sharpest factory serrated edge I have ever seen).

Edge holding:

OK, after slicing up all of the cardboard that I could scrounge up, both the Pacific Salt and Calypso Jr. are both still shaving sharp. The Calypso Jr. is still popping hairs and the Pacific Salt only pops them occasionally on the small serrations and is scrape shaving on the larger ones, VG10 seems to have the “edge” in edge holding. Considering that this was only a very limited comparison of two differing knives, I will defer to Sal’s CATRA testing for the real answers. I will say that the H1 held out longer than I would have expected from AUS6; there just may be something to the extra work hardening in the SpyderEdged Salts that Sal mentioned after all. ;)

Frank, thank you for the info. looks like there will be another knife in the stable for me!

Thanks again for your time. Walter
 
I'm wondering how we can tell what kind of clip and washers we have when we purchase one of the Salts.
 
Well, when I upgraded the body of my Salt 1 I cut the old FRN one apart and I did not see any washers per say in this particular Salt anywhere.
 
The washers are on the outside of the handle at the pivot. They are coated black. They give the pivot steel to press against during riveting. Makes for a stronger knife.

sal
 
Oh yeah. I see that now. I had to go grab the old handle. When I read washers I was thinking phosphorus bronze or nylon for the pivot.

My bad. Thanks.

What a great thread.

Brought it back up for those who haven't seen it yet.

H-1 is amazing. After reading this thread.......I'm going to buy a Salt-1. :D

Thanks Sal, and Frank!
 
I believe there is a certain problem in getting H1 to oxidize, given that it's made with nitrogen...
 
I have a Salt lying in the Dead Sea as we speak. I will check on it in January.
Lat I checked, a little rust around the washers-nothing on the blade that didn't rub off with a chamois. If it won't rust in Dead sea water, it won't rust in any naturally-occurring water on Earth. (I don't think so, anyway-- very salty water-very heavy in potassium, magnesium, and a few others.

If you simply want to destroy the blade, put it in concentrated Iodine for awhile--that'll do her. Of course, that is not a "real-world" sort of test......
 
Actually was thinking about this the other day. When I got a small Salt I, I used it to cut foods and left it on a windowsill afterwards (did not wash it beforehand). I'd clean it off after a day, and cut more foods. No rust was noticed.

I tried the blade in saltwater for a day, no rust

Washed the knife and did not dry it off, let it set on a windowsill for a day, not rust, not even discoloration.

Ran the knife under water, left it in a shower caddy for a week, no rust.

left the knife in a pan of water for two days, no rust. Repeated this for about a month. No rust

After above pan soaking, left the knife, undried on a bathroom rack for a week, no rust

Just plain left the knife in the bathroom, after cutting some sappy branches, for a year. No rust.

After the year, cleaned it, and sharpened it to a scary edge with a few passes on a Sharpmaker. Looked at it with a magnifying glass. No rust or discoloration.

If the Dead Sea donesn't rust it, I'll be convinced it just won't rust :D
