Gentlemen....

A kukri is not an axe. An axe has a nice long wood handle to absorb shock....and is quite a bit different than a kukri that has metal tang that - though substantial in thickness - is still quite a bit thinner/lighter than the blade itself and has very little ability to absorb shock.



What we need to do is get back to the facts and not allow conjecture to take over.


"I've never broken my kukri while batoning" does not mean "My kukri is baton-proof". Just means you're luck has yet to run out. ;)
To conclude the above statement would be conjecture, not fact.



The first fact that I can see (based only on evidence shown and my experience with breaks in kukris) is that the break is a "clean break" and is not from a weakness brought on by poor heat-treat or imperfections in the steel.


The second fact is that it broke while bringing the blade-stuck-in-the-wood down onto the ground.

Could it be possible there was damage already there? Yes.
Could it be possible it was the first time it was stressed? Yes.
Could it be possible it was a stress riser from the cho? Yes.


These are possibilities, but are speculations....conjecture....they cannot be drawn into conclusions.


For example:

The cho might indeed be a stress riser in every kukri (many knives have stress risers in them simply by their designs). But that alone is not enough to say it is a 'point of failure by stress riser'. I would think that the hundreds/thousands of kukris owned/reviewed by forum members here alone should be evidence enough that even if the cho is a stress riser, it poses no danger for failure. By comparison, the failure rate is very low....meaning the success rate is very, very high.


Like I said, and has been echoed here....many a knife owner abuses their knives all the time (I do it too)...sometimes they fail, sometimes they don't. Those that abuse their knives without failure = I count this a "luck"....not "proof" of success, etc.


Let the failure be what it is.....1 out of a 1000 (or more). Read up on the other 999+ ....if you need proof the CAK is a tough kukri.

And axe handles are cheaper and easier to replace (for those that can properly set an axe head at least... which counts me out :().

If I should ever use an HI hard enough that it should break from sheer metal fatigue, rather than a defect in worksmanship, I'll consider it well worth the money anyway, and be able to justify another new khuk purchase a little easier. :D

As Always...Err on the side of Caution,Safety and Common Sense when splitting wood with your khukuri. It may be alright to Imbed the Khuk in the log and then strike them both to drive the khuk thru on a limited basis( once in awhile) but to do this as a daily practice would be asking for a failure. While H.I. khukuris are built tough, they are not super utility tools.Steel and design limitations are present in all tools and sooner or later are prone to fatigue at some point causing failure.Proper Batoning methods should be utilised and for tougher jobs maybe an axe would be a better choice for the job, use your common sense in deciding what method and tool is best suited to the task at hand.

Gentlemen.

My replacement CAK arrived today!!!
I'll have to wrestle the camera from the wife and get some pics of it up.
My first impressions.....absolutely love it. Thank you Yangdu.
Just eyeballing it but I would say it is a bit longer than my previous CAK, but more notably the blade has to be 3/4 of an inch wider and prehaps a hair or two thicker.
Strangely though, this blade only feels a little bit heavier....and seems to be a bit more fluid in the hand. :confused:

I'll post some pics in a new thread after I have a chance to really play with it tomorrow.

To everyone that has hopped in here, thanks. We seems to be fairly evenly split on whether or not this was abusive on my part. For the most part it doesn't matter to me as I am not likely to do this sort of thing with it often. I am a big believer is using the right tool for the job, and I have a bunch of tools dedicated to firewood. :D No need to abuse a tool. Except tomorrow. Tomorrow....I make this khuk howl.

As long as you didnt do it on purpose and were honest about it...thats what matters. Enjoy your new khukuri, use it wisely and in good health.

If you havent already...please read the safety thread!
(I know ya hear that alot....but for good reason.)

As others have said, if and when Busse Combat makes a Khukri (there's talk that it'll happen this year), I'm confident it will be an outstanding piece of steel and that many people will buy them. However, I'm also confident that they'll be priced in the $500+ range, so I'll probably pass. If Scrap Yard releases a khuk, I'll likely buy at least one, but they'll still cost a lot more than an HI and probably be no "better", just different.

bill siegle makes some of the best custom choppers i've seen. he makes a khukri like object, that has to be seen and used to be believed. it's awesome. it's really close, imho, to what a khukri "should be", however (and with all due respect to Mr Siegle), it's not a nepalese khurki. it's its own thing - his thing. considering it's custom, 5160 differentially treated steel, the price is VERY reasonable. everyone should buy one or more of his pieces.

bussee makes some very tough, and very expensive knives, no joke. however, you almost never can buy them (or the sister company knives) at msrp, the cult doesn't allow it, the people who makes a fine living reselling the product, less so (hahhahaha). i imagine a bussee khukri-like object would sell for msrp of, let me float a guess here, $750 given the various factors. they would be sold in limited lots. there would not be a snails chance in HELL of any random customer being able to buy one, the HOGs would buy them 10-15 at a time, or more, for resale. you'll then see them at $1500. just watch. i'd love to be proved wrong and see them made in the 1000s for $150 - i'd even buy one then. still, they won't be khukris.

i have... a few... khurki like objects. they are not true khukris imho. they might be fine knives, but they do not have souls. they do not perform like khukris should. they're just "big knives".

and Yangdu is to be PRAISED for her initiative taking a business loss, and providing a warranty on a knife that was at least second hand, *modified*, and perhaps over zealously used... i do not imagine, for a moment, *any* company, doing that. not for one minute. this is why Himalayan Imports is THE khukri company as far as i'm concerned. if you want a good value big knife, buy Becker :)

praise be :)

Glad to hear it arived safe and sound. I'm looking forward to reading your review and seeing the new pictures.

I've handled multiple blades of the same type and size and they can feel very different. It's how they make it. Sounds like you got a sweet one though.

i don't think batoning is abusive, unless one uses a hard striking instrument (hammer, pipe, [sharpened] crowbar, rock, another khukri, anvil, vice, ...)

a good tough knife should be able to handle batoning wood relatively well, and a CAK is that, to be sure.

when you were batoning, were you striking the middle-spine, or near the tip? or the cho? ;) j/k

a new khukri saves the day.

I bought a Bahadur from another source and it had a crack where the cho should be,edges were very sharp as were the corners. Took pictures and sent them a email, they replaced it but made me pay for postage, they didn't want the cracked one back so I filed out the crack and rounded all the corners,it's about a 1/4" narrower across the blade now.

I'm back. Unfortunately my computer's hard drive decided that Tuesday was in fact a good day to die. I will get some new pics of the new Khuk up. I will get the broken khuk off in the mail tomorrow.
