Hi all!
Hard use testing of Knife Research Legion knife
Such a big knife
and it's really a small Roman sword
Knife is absolutely new, sharpness check
It is very sharp. The paracord just pops off
Begin with an apple
A memories from a Knife Research Enki hard use testing are still fresh in my memory
and I can say that this knife is cutting very similar to Enki
They have approximately similar blade geometry
although a Legion is a bit harder to cut with
but a blade spine is very thick here
Nevertheless I cannot say that it's ripping, it is cutting
Well, it is a very good cutter
Moving to a more serious tests
wood chopping
Well, aluminum chopping
It just cuts off pieces of that tube
And I still don't see any damage on a cutting edge
Let's test the tip
A testing is progressing much faster than I expected
Well...
Continue with tip testing - punching 1mm stainless steel
After 5 punches there are very little light reflecting spots on a cutting edge
I'll do 10 punches perhaps
10 punches of 1mm stainless steel
a little crumple here, but a tip is undamaged
1.2mm stainless steel
A little damage on a very tip here
And moving to 1.5mm galvanized metal
I can't even say. It seems like a damage left the same as it was before
Back to cutting edge testing, tube batoning
Cutting edge is totally fine
But there are little dents appeared on a spine. These 2 dents.
Next chopping of 3mm steel rope
After 5 chops we can see light reflection here on a cutting edge
Nothing serious
Next moving to batoning
A wood is a bit springy
Near the groove, a spine is just broken inside...
Here you have a Legion...
- You've got an excellent tactical awl
I don't know about it....
Take a picture of this breaking surface here
A surface is pretty homogeneous
But is started from here, via the groove, via the weakest part
And then here we have some bright spot which is unexpected
- What is the blade thickness here?
I think it's around 6mm
- And here inside the groove it's only 1.5-2mm
Yea
Surprising
That's what you meant by tactical awl?
- Yes
- You can sharpen it ;)
I see that metal structure is very homogeneous here
I can see it. Grey and very fine
And 100% that a crack has started from this spot where spine has broken
Then via the groove and to here
That's how it's broken
Under the scales to a finger groove
It was a batoning and a load was like this
and that's how it opened, via the path of least resistance
A strike was probably around here
although I remember that a last strike landed in this area
Very sad result
I didn't expected this at all
That's all, I said everything that I could
In some jobs this knife was just shining, it just blew me away
But then when the hammer came to play, it's just crumbled
That's all. We'll see what a Knife Research have to say about it
Because evidently, this groove doesn't seems like a good solution with this steel
A steel is pretty soft and it started to bend early and eventually broke in a weakest spot
Maybe it withstood if there was no groove
But it's just my guesses, we'll see how events will develop further
Thanks to online shop www.lamnia.fi for assistance in purchasing this knife
I am very thankful to these guys, you are doing a great job. It is a pleasure to deal with you.
That's all, I hope it was interesting to you
Thanks for watching, see you, bye bye
Everything is pretty much clear but I cannot hold myself from asking one question
that I have after all that I saw
This is Knife Research Enki knife with Vanadis 4 Extra steel and declared hardness of 60.7HRC
Knife has passed a hard use testing and was beaten with a 2kg hammer on the spine
Here is a condition of it's blade spine
This is CRKT Ultima knife with 4116 steel and declared hardness of 55-57HRC
Knife has passed a hard use testing and was beaten with a 2kg hammer on the spine
That's how a blade spine looks like
With a fact that spine thickness here is 2mm at maximum
This is Gerber Bear Grylls knife made of 7Cr17 steel with unknown hardness
Knife has passed a hard use testing and was beaten with a 2kg hammer on the spine
Here is a condition of it's blade spine
And this one here is a Knife Research Legion knife with
German Sleipner steel from Bohler and declared hardness of 60HRC
Knife has passed a hard use testing and was beaten with a 2kg hammer on the spine
and here's how a blade spine looks like
This is not about a groove, the spine has chipped per se
Even here at this spot where there is no groove
we can see a dents that left after hammer strikes
i.e. what it is more like?
This?
Or this?
What upsets me is that Legions spine is more similar to this and this which nave a very low hardness
Knife that is having 60.7HRC hardness just isn't receives dents at all
only some micro damage and marks
Here a spine has just destroyed
Thus it is a very big question: what is a real hardness on this knife?
Share your thoughts with me, maybe there will be something interesting
OK, this is it
Thanks for watching, see you, bye bye
