Magna-Cut versus 3V corrosion test

I tested Bark River Magna-Cut and 3V to show that the Magna-Cut is not just 3V labeled as Magna-Cut.

Thank you, these have been an interesting series of videos.

I have a SURVIVE knife in 3V. I use it at home and wash it with tap water and let it air dry with dishes. I did not see any rust or discoloration on it. Magnacut is more resistant to corrosion but no stainless steel with carbon is completely resistant to rust if exposed to salt. The only exotic rust proof steel is H1 steel.

Bar keepers friend and some scrubbing will help remove it.

It is magnacut. Its a combination of the heat treat being wrong and how they grind it. But also how they handled the situation at bark river by not fixing the problem. No one else has that issue.

Survive knives also had the issue and they use the same heat treat facility and hot grinding. They had to coat those models to recouped the costs. Bark river just sold them and won't take them back and lay blame by saying its not stainless.

Other brands had 62 plus without issues. Bark river can't take them back and replace them because its so expensive and I'm not sure if the heat treat facility resolved the issue or not. It seems like they may have via what survive knives has said, but bark river is in denial that anything wrong happened. Again cause they don't want to loose money. Then they have to find out what to do with all those defective knives without loosing more money.

All Cause they didn't bother to do their own testing. Customers are the beta testers. Doesn't make sense, right? They mskd s nice looking knife but cut corners everywhere. Then make up excuses. Customers get scammed in the end.

I don't know squat about magnacut. But it's interesting that we're talking about Bark River knives. The one Barkie I own is fine, but I've heard quite a bit of mixed opinions. Mind you, they sell so many knives, there's bound to be issues...

I have Bark River 3v and Magnacut knives and both spot rust.

Magnacut is not stain proof. No steel is. I have used ferric chloride to etch a gray matte finish onto one my Magnacut blades. Granted, it was highly concentrated FC, and I mean almost straight up FC, but it did stain the Magnacut. I did it to hide the damned scratches I couldn't completely get out of the blade when hand sanding. Magnacut is hard to finish, lol.

Magnacut isn't stainless. Spyderco using it in the salt series is a mistake on their part.

Mike Stewart has already said Magna-cut is not stainless

[darrylsowade]

So youre comparing tool steel to stainless?

[gunner]

This test is a good one. Shows the actual properties. That's a standard reaction for 3v and Magnacut. Magnacut is not a true stainless. It's better than D2 in that way, but so is 3V. Hard to tell how much better. Definitely not a salt knife. Spyderco would never do that. They have invested to much into the Carbon free steels.

I agree Magnacut is not a stainless steel but is highly stain resistant.

GOD… YOU MISSING THE “HEAT TREATMENT FACTOR: HIGH TEMPER LEADS TO HARDNESS AT THE EXPENSE OF LOSS OF CORROSION RESISTANCE, WHERE LOW TEMPER MAINTAINS GOOD HARDNESS BUT NOT AT THE EXPENSE OF IT. BARK RIVER IS HARDLY RELIABLE WHERE HEAT TREATMENT IS CONCERNED
