Thank you for the call out guys - I appreciate it.
Smodtactical - when you say you want a strong knife, it really comes down to defining what that means. On one hand, the HI blades are a huge chunk of 5160 alloy steel. So the base metal used is a very sound choice. Second, the blade is hand forged by craftsmen who know what they are doing. Third, it is differentially, or "zone", tempered. This means the cutting part of the khukuri is hardened to hold and edge but the spine is not. This allows the khukuri to flex and give without being so brittle. Fourth, the thickness is amazing - these aren't going to break/snap without an unbelievable amount of stress. Fifth, because of their design they are field maintainable - you could, in theory, hammer them back into shape and/or sharpen them in the field - the Nepalese people have been doing so for a very long time.
So, what you wind up with is a hand crafted blade that is handmade and unique. You aren't going to find too many out there that are tougher in terms of not failing on you. Moreover, HI is awesome about standing behind their blades and offering great customer service. There are real people and blood, sweat and tears behind these knives.
The folks are giving you some great advice. The chiruwa ang khola (CAK) is one of my favorite profiles. It is a chopper - meaning it is very heavily made and it's weight distribution favors using it for chopping things such as wood, etc. I am 46 and my wrists and elbows have a lot of problems. I used to go for the biggest heaviest knives and khukuris I could pick up - the bigger and heavier the better. The problem I have now is holding on to them. I have actually sold off all my personal khukuris bigger than 18" because of their weight due to my physical limitations.
My point is that the HI khukuris are all very well made and any will serve you well. Put some thought into how you want to use them - including how long you will have to carry them and how much weight you'd want to carry. A person using one at home to cut wood will have a different perspective than a backpacker who goes on long trips into the back country.
Hope this helps some.
