DPX HEST Sleipner Steel: Corrosion Resistance?

[anthony cheeseboro]

I have a Sleipner steel Hest. I carry it sometimes, and it is still shiny, but it has been very cold, and I have not been sweating. How does this steel hold up against sweat and general humidity?

I've used my Sleipner HEST fixed blade in a lot of wet areas and never had a problem. I don't carry it in a way it could be sweat on a lot. Over time I think I've noticed the Sleipner to be a bit more susceptible to staining in general than some other steels though.

With only 7.8% chromium, it isn't going to be "stainless", although I would expect it to be somewhat more corrosion resistant than carbon steel.
I get spots on my D2 blades, and D2 has 12% chromium.

That's what I want to hear. I started to sell this knife, but it fits my hand perfectly. I expect to use it a lot outside this Spring and Summer. Right now, it is just cutting open bags of road salt.

That for composition break down.

I have one of the SR1s in sleipnir. It would surface rust while wearing it as a neck knife in my fire turnouts until it developed a patina. After that it was very resistant to the swelter that is fire turnouts. It still looks shiny but it now has a different hue to the metal.

In August 2014 I carried my LionSteel SR-2 in Sleipner tool steel for 10 days straight. I did not rinse it every day. It was exposed to humidity, water, sweat and dust all within a somewhat hot and humid climate a few miles from the Pacific Ocean.

What actually happened is that the blade is now stained with patination. The black spots are the tiny old pits and the discolorations are the stains/patinations. The pits are only on one side (lock side) and from lower front to tip. The stains will not go away with Flitz.

Sleipner is a tough tool steel which is easy to sharpen and used in meat processing but requires maintenance. If you're in a salty, sweaty, humid and corrosive climate I'd recommend a more stainless steel.
