MAGPUL's new knives.

[Cobalt]

As mentioned.. mim isnt new to gun people. Its cheap trash for guns, itll be cheap trash for knives.

This is the correct answer to this thread.

TRASH!! on any use requiring strength.

MIM is fine for low strength requirements.

Hopefully this doesn't make me one of PT Barnum's kids but I ordered one. Besides the obvious curiosity how a MIM blade will hold up I'm also curious about the lock and scales.

"Lug lock that interfaces with the unique blade."

"Proprietary black polymer handle scales made from a super plastic that has a carefully guarded recipe."

And I assume the pivot will be riding the polymer:

"Flipper opener riding on a built-in friction reduction system."

Super plastic...

I'm interested in your first hand feedback over time...im assuming you're gonna use it?

I don't have any hard use in my daily life but yes I intend to use it. The worst thing my pocket knives ever see is the invisible copper coated steel staples they put in some boxes. Which I hate hitting but it's a sure sign if the edge chips, rolls, or laughs at. I won't do it on purpose but it tends to happen. Otherwise I'm cutting boxes and packages open (I work a logistics job where I'm opening and bringing stuff to people that order), cutting plastic strapping off pallets, the occasional rope cutting.

But I also confess this is a purely novelty purchase. I don't expect to be blown away by super plastic and sintered steel. I'm in that club that still owns a Colt that the original sear broke, and a S&W where the hammer spur snapped off. But that was also thirty something years ago and I'm hoping we've moved beyond that kind of thing. I'm also sure the usual knife tubers will be reviewing this the minute they drop. Looking forward to the bro science in the Knife Lab from Pete.

On one of the videos it was mentioned that the MIM blades are HIP'd* then they receive a normal hardening process like any other blade. They are fully hardened, not like early MIM where it was more of a case hardening. It's also claimed that they are as dense as "normal" hot rolled steel blades. Again, all of this needs to be 3rd party confirmed before I blindly accept it.

You , or "somebody" , owes it to science, to really JoeX a MIM knife !

Maybe someone will use MIM to make other knife parts, say a pocket clip.

Or maybe a whole , one-piece fixed blade ?

I don't make the kind of money to "JoeX" any knife... But I will surely cut anything in my daily stuff. I at least promise not to hold back. I've treated my Delica in K390 similar and it's still the factory edge with only a ceramic rod to hone it. And that was only because of those awful staples. But I look forward to the inevitable JoeX video with this knife.

Not sure if MIM makes a spring steel or not. But then there's other grades of steel that don't make a good spring clip so I'm not sure this would be an argument or not. I'd think MIM could make any other small bits like thumb studs or similar. I'm suddenly curious how the Microtech Amphibian thumb studs and lock release are made. That would be a lot of 3D milling easily replaced with MIM if they aren't already.

The Kershaw patent covers HIPing of MIM knife blades. Doing MIM doesn't necessitate any specific kind of heat treatment. Case hardening would be a separate decision. A conventional heat treatment process would be the most appropriate. Typically after HIP there is a very small amount of porosity that is eliminated in hot rolling. Of course the small amount of porosity may not be significant, depends on the test being performed and the size and volume of the pores. I believe Magpul gave a number for porosity, unless I am confusing it with numbers that Kershaw gave for their process.

KAI/Kershaw holds the patent.

So, is Magpul licensing it from them?

Deadboxhero posted it on the 1st page.

It’s possible one reason for the price of these knives is a result of royalties being paid on KAI’s patent. I have no idea if that’s true or not, but it could be why an “affordable” MIM knife is almost $200.

I pre-ordered one if only for the novelty of it. I spend a crap-ton of money on knives yearly, this isn’t going to even register as a blip.

The thing about Magpul making bold claims on its knives is that gun guys and knife guys alike are going to abuse it for science. If it sucks, we’re going to know quickly.

 

[SharpBits]

Has anyone looked at the prices of US made folding knives from other companies lately? Knives in the $200 range is pretty common these days, sadly.

Not if you're specifically marketing a knife as using so-called cost saving technologies.

It's just cheaper than a Chris Reeve knife.

They probably think their knife is worth more than $200. They wouldn't be the first in that, either.

This logic from some brands gets me. Confession up front I'm a bit of a Spyderco fanboy, but they are a brand that offer almost always top shelf heat treating and interesting new steels. And a quick check of that brand on Knife Center shows 26 results for less than $215 between just the PM2 and PM3. And you're getting MagnaCut, 15V, CruWear, and other interesting steels besides just a variation of S35VN with Super Plastic.

 

[Snacktime]

Besides the MIM edge worthiness. I am having a hard time with the price and injection molded handles. Looking at all the text cut outs with pivot design that can pack gunk in makes me question design. I foresee this being a well selling item at chain stores.

I can already see a couple problems here.

We were advertised that they were the first to do something with a new technology for knives yet Kershaw was first 20 years ago.

We were told they would be able to offer the same features of super steels for a much lower price than what's on the market. However it's offered at $200 which completely ignores the market.


So, it's not looking good.

 

[SharpBits]

Not sure why I'm selected as the apologist for Magpul, but here goes, I guess. What Magpul actually said "Now, we're bringing MIM capabilities to a space where others have not perfected it: knives."* I don't care enough to know if others have overstated any claims. Seems that they believe they have perfected what others (Kai) have done before. On their webpage they make no claims at being first in this space with MIM. Their steel might be a first, but I'll leave that for you to sleuth out since you have contacts in the business.



Clipped from a larger picture on their webpage.* That complex blade design (that u-shape, not the pin) is not going to be affordable using CNC due the extreme waste of material it would require. It is not even possible with simple stock removal methods. So, from their point of view, manufacturing of complex designs will be far less expensive. However, I believe the new knife should have been priced lower than the Bugout.

I'm still in the wait and see mode. I'm neither going to knee-jerk "hate the new thing" nor am I going to be first in line for one.
