Good point - I did not think to check the pivot hole face on the blade!

On a broader note, missing in this whole corrosion conversation is the fact that really the only place where rust effects a knife's effectiveness is on the edge itself, which by definition is not coated.


When an uncoated non-stainless blade gets corroded enough around the pivot area that is doesn't want to open or close, I'd say that affects performance. On the other hand, a rusted edge can be easily ground to a fresh shiny edge!

Here's why they coat it. Couple of hard use hunting trips... Please excuse the inferior brand... It's a knife I gave my brother in law as a gift a few years back.



Imagine the average user who drops $200 for the first time on a high end production knife. Then after a few months he's peeved because "I thought this knife was supposed to be the BEST!? It's rusting just like my $7 WalMart knife..." then he launches a personal campaign against BM slandering them because his knife is rusting...

It's wise for BM to coat the blades, I'd love an uncoated M4 blade but the coated blades make sense.

I'm curious. Did you care for it properly? Or did u treat it like a stainless.

Edit:
I read the post incorrectly. I would assume he didn't care for it properly. By the sounds of it I highly doubt he would ever have purchased a M4 blade without coating on his own.

Ya Tiawan steel will do that, I have one of those also. Just cause it says colorado doesn't mean that's where it was made.
The new southard for 300.00 is taiwan also I heard.

We are talking Benchmade steel,Oregon USA baby, aint that right Tony! Totaly different animal in that picture,just cause it was 200.00 doesn't mean it wasn't a 8.00 knife in the begining. And it looks like it was left in the bottom of a tacklebox for the winter lol.

I really wonder, though, if that has as much to do with the fact that Benchmade sends out every knife lubed with Militec-1 -- which is horrible at preventing rust and almost seems to be a catalyst for it -- as it is the steel itself.

Did you by any chance take pics of the rusty pivots/tangs as you opened NIB knives? Sending those to Benchmade might be enough to get them to quit using Militec-1 on their M4 and D2 blades. I don't let it near any of my knives.

When I got my 520M4, I immediately disassembled it and cleaned off the Militec and the surface rust, and re-lubed with Weaponshield. Several months later when I disassembled it again, there was no rust at all.

That Mule I do believe was made in CPM-M4, and those were made in the US.

Looking at it, I'd say his brother-in-law did not know how to care for carbon tool steel.

Mine said 52100 steel before I sold it.

AISI 52100 is a high carbon tool steel containing low quantities of manganese and chromium to improve hardening. Because of the low chromium levels in 52100 steel, it has very low corrosion resistance compared to other higher chromium tool steels.

In applications where corrosion is less of an issue, 52100 tool steel is considered an ideal, affordable option, offering a very fine grain with superior edge retention. It is capable of cutting a wide range of materials because of its combination of toughness, wear-resistance, and hardness. This would explain the rust

It 's a good thing that Benchmade coats it but non coated should be an option too...regarding the M4 steel it rusts if it's not taken care of like in the picture so it's not the brand's fault...Smiler


Cut that or shut up!

If you go back to the original post, the corrosion on that blade was caused by skinning and gutting a deer then putting it away *wet* - not even wiped down! - and leaving it. You could probably induce rust on quite a few "stain-less" steels with that treatment! Big Grin

Imagine the average user who drops $200 for the first time on a high end production knife. Then after a few months he's peeved because "I thought this knife was supposed to be the BEST!? It's rusting just like my $7 WalMart knife..." then he launches a personal campaign against BM slandering them because his knife is rusting...

It's wise for BM to coat the blades, I'd love an uncoated M4 blade but the coated blades make sense.

Which Taiwan steel would you be referring to? The Americans who made the steel in that blade, and the Americans who make the steel in the Southard, like the Americans who make all of the Crucible and Carpenter knife steels, would be pretty ticked to hear that you've off-shored their jobs. Frowner

Is Militec-1 the same as Benchmade's Blue Lube? I always assumed Benchmade was using their own knife lube on their own knives. Is it just re-labeled Militec-1?

In my location, it is so dry that I don't get a true read on how well various lubes work on rust prevention. As far as I know, Militec-1 proved itself over in the sandbox keeping our military's weapons functioning where sand gets into absolutely everything and it seldom rains. As a lube I have found that it works as advertised. Since most of my knives are M4 or M2, lubed with Militec-1 and occasionally rubbed down with a little WD-40 to displace any water and remove finger prints. So far, no rust on any of them, but like I said, that's probably from my dry location. I'm sure if I lost a knife out on the lawn where the sprinklers hit it, it would be a rusty mess.

I'm not against trying your Weaponshield. Do you have to buy that online? Where should I get it?
