I was looking at the Busse forum and came across this link, has anyone tried to chop a concrete block with an HI khuk ???

If not, is anyone prepared to ??

Concrete block chop

Pretty impressive !!

:confused:
 
id love to do that with a khuk and see how it does. only problem is, it would break my heart.
 
In the thread, somebody was bending the knife to 90 degree. Doing that to an HI khukuri, it will break my heart mentally and physically.
 
Maybe I am just too damn old but, I don't care about chopping concrete blocks or bending a knife 45 or more degrees. I used my 18" WWII all day today cutting a awful lot of cedar. Chopped the stuff up in about 6" pieces every thing that was trimmed from three trees. All day long and and never had to sharpen the blade. Just kept on cutting just like I knew it would. The fine stuff as well as the 3" limbs. By late this afternoon I was starting to get a bit tired and the three inch pieces were taking three and four chops but that isn't the blades fault.

That is two days with the 18" and a whole day with the 16.5" neither had to be sharpened and, I had no complaints about the performance what so ever. That's all the testing I need to tell me these babies are set to go.:) :D
 
I saw this done in person at the Blade Show in Atlanta this year. It was a site to see! I think 5160 would hold up well in this test. I have not chopped a cinder block but I have hit cement full force a few times missing my target and the edge (sweet spot) was just a little blunted and it chipped the cement quite a bit. I might try this and post some pictures when I get a digital camera.

As for flexing a khukuri I'm not sure it could be done as the blade on most models are to wide and thick, I think the handle material would be destroyed befor the blade bent.
 
I'm pretty sure my 20"AK would do it, but I'm VERY sure it won't be doing it!!

The nice thing about the khuks (esp the Big ones) is that if you had to bust up a cinder block (trying to think why:confused: ) you could always turn it around and hammer the block with the spine--heck put a cloth over the block first and you might not even damage it! Thereby leaving that beautiful edge undamaged:)
 
Concrete was meant to be broken by hammers......or martial arts type guys, not knives. It's an impressive feat, but if somehow I needed to use a knife to break down a block, something has gone very wrong, most likely with me.
 
The guy who came up with the idea of busting blocks with a knife has obviously busted too many of them with his head.

I've seen the concrete chop used to sell some strong but cruddy swords before.

As a sword or knife is not really meant for this sledgehammer task, it should be undertaken with caution, and you must assume that the knnife will be irreparably damaged. If you can live with that, then happy chopping.

"Amazing, it's still hammer-sharp!"


Sorry, not impressive for a knife. How many blocks could one bust up with a baseball bat? Performs as well as stick technology?

I don't think that even the Ginsu guys would want to try this line, no matter what meds they're on.
 
Ought to be able to break it with a good sideslap, let alone a spine strike.
 
I'm with Pappy and the others that think this is silly. I've never been attacked by a cinder block, never been hungry enough to eat one, and the durned things just refuse to burn in the fireplace. A knife that holds a good sharp edge, and can be easily resharpened in the field, is worth far more to me than some of the wonder knives out there that are admittedly hard to dull, but dang near impossible to resharpen without the use of industrial diamonds.

From that thread:

This test really proves several things.
1) Incidental contacts with stone, concrete, rock while using a Rat isn't going to cause any problems and you will be able to resharpen the blade yourself.

2) The Rat won't chip out when using it on bone or other hard material, even with hard impacts.

Also, if you do have contacts with stone, concrete, etc while chopping you don't need to send it back to have the damage ground out. You can do it yourself.

Many of you are completely missing the point if you only think, "Oh, wtf would I want to cut through a concrete block for". It's not the obvious fact that it cut through a concrete block...it's everything associated with it's ability to do that, such as not chipping, hardly being dull, etc.

I won't be using any of mine to do it for sure..:eek:

I like mine too much. :D

But if someone who was asking wants to "GIVE" me one to test I would be more than happy to break a few....LOL

I am sure they would hold up fine..:)

I do not agree:

It proves that a friable cinder block can be purposely chopped without severe edge damage.

I agree that the edges of many knives could be severely damaged by this deliberate act, and have heard and believe that the knife is a fine one.

IMO, striking a hard rounded metamorphic stone such as granite river stones, or a frozen elk or deer leg bone with direct and particularly glancing blows would more convincingly demonstrate practical toughness though the theatricality may be diminished. I suspect that both are a more severe test than the construction block.

Of course, anyone with any sense would use the rock to break the bone or the block.
