Cold Steel LTC Kukri Carbon V BREAKS in half šŸ˜µ (Video inside)

not enough info to guess at it....but nothing lasts forever...hate to see a blade die, but glad no one got hurt.....
 
Video states less than a minute of chopping, and steel looks clean.

It does look like a 90 degree stress riser at the transition from the blade to the stick tang.
 
The Carbon V stuff hasn't been made in years, either. That said, it could be a bad batch/one off. A traditional khukuri generally has a very soft tang to prevent that sort of failure. However, it is not uncommon for an oopsie to happen where the kami (bladesmith) splashes a little water too close to the tang and hardens what was supposed to be left soft. I've often thought the stock of the CS khuks was a little thin for a blade that is going to be swung hard and torqued on a lot. I'm also guessing that they aren't differentially heat treated, but maybe they are. You have to walk a fine line between too soft that it will bend the thinner stock and too hard that it will shatter under stress.

Glad no one was hurt.
 
Wow! Is that what it is designed for? I was thinking brush, sapling, flesh, etc. I mean a hatchet or axe is much more rugged for that type of thing. Maybe it should not have broken, but I would not use that as he is. I guess its just me but I scratch my head every time I see someone using a knife instead of a better tool, and it breaks.

This was the LTC (eg the machete version)

The LTCs were Carbon V. The machetes are 1055.

True, there were no Cold Steel machete back then, and the LTC was the machete-like knife. Still it is a relatively thin blade which was not intended for processing trees trunks. I suspect metal fatigue from repetitive lateral over stress.

I had forgotten that.
I actually had a Gurkha Lite back in the day. It was a really thin stock of Carbon V. Smaller and narrower than the LTC, but it was a good chopper within its lane of use.

I ended up gifting it to a coworker when I discovered HI almost 2 decades ago.

Thinking back on it, I could see how it could potentially fail. I never managed to break mine and even threw it into a few tree stumps, but that is a pretty thin spine for such a long, wide blade and not spring tempered like a machete.
