Thanks again for the input gals and guys, I'm getting much closer to a decision.
I don't want to sound like I am flaming you, I just really want to try to understand and if you really want to make sure you get a full tang then there have been some good suggestions for them above. But, when you talk about needing a full tang because it will be better balanced. Realize you don't want a better balance. For chopping work, you want the weight over the sweetspot, where it will do the work for you. Allow the tool to do the work, don't make your arm do it. Also look in the HI "stickies" for the proper chopping technique using a Khuk and your wrist. It is much different than using an axe, but the right technique will be very helpful to your prolonged chopping.
I'm actually quite glad you called me out on that because what you are saying makes perfect sense, particularly for a blade of this shape and intended usage. Believe it or not a similar thought crossed my mind today as I was day-dreaming at work about these kukris.
With this size of seasoned hardwood you definitely want to go with one of the larger models. Also, consider sharpening up your axe for some of this big stuff.
A khukuri is still a lot of fun, if not the dedicated tool an axe is. I highly encourage you to give Yangdu a call. She will quite likely be able to fix you up with something not on the website, or a blem with cosmetic flaws that meets your needs at a reduced price.
My axe just isn't that great in general, it's merely decent. Head is an older "True Temper" which probably isn't a terrible company but I haven't done my research so I wouldn't know. Handle kinda sucks too, grain isn't straight and I've had to repair it several times. My original plan has been to eventually have a woodcutting "team" consisting of a higher quality Swedish axe like a Gransfors Bruks or something similar as well as a one handed tool to break up the monotony, which I've now decided will be a kukri from HI. As much as I would like to collect collect collect fine blades of all types, fact is I'm a poor-ass college student paying out-of-pocket for college and living on parent's land to avoid rent, so my expenses in this area must be limited and carefully thought out. Whatever I buy will be a TOOL to be used for my personal advancement, and a well made tool always receives my love, care, and respect. And that's the plus side to living in the country and not the city isn't it? That there are TREES to play around with, a hobby that I much enjoy.
Chopping is a great psychological outlet for me and also an interesting and fun way to gauge my on-going weight lifting progression, so I know my Khuk is going to be WORKED.
As for emailing Yangdu, I did indeed do that last night and here is her response today:
"First of all welcome to the HI and blade forum.
The Chiruwa Ang Khola comes with full wide tang strong and steady.
Right now I do not have the large size knife with chiruwa handle in sock.
You are welcome to order any size knife with chiruwa handle and once I get your order conform then I will send to my shop manager and Kamis.
Let me know
Thank you"
That sounds like some damn fine customer service if I've ever heard of it. I don't think it'll be necessary for me to go that route as I'm willing to give the rat-tang a shot, but it's still very heartening to receive that kind of service. She certainly has my loyalty already. I'll be putting whatever Khuk I get to the test with some serious usage, so if it breaks or bends, well there is always their reputably very reliable warranty.
For regular or lengthy chopping sessions Id go with the 18" AK or CAK. They are a bit lighter for extended use. KLVUK is a great all around knife but it doesnt have the weight you need for what you are describing. Anything over 3-4" diameter will be a challenge to process with any regularity although it can be done. For heavy chopping the edge geometry of the AK is really better suited. They are thicker behind the working edge.
Awesome that you posted that my friend. I've been thinking all day that I'm likely going to decide between an 18" or 20" AK. Ganga Ram looks great too but the shape of the AK is more pleasing to me and since they are likely both great choppers, I guess aesthetics does come into play under those circumstances.
Can you or anyone else who owns the 18 or 20" AK models give some input as to the average weight that comes through for each? I'm very tempted for the 20" and 3 pounds would be absolutely perfect for me, however I'm a bit frightened that I could get a nice fat 4 pounder which would be too heavy. I bet I could just ask Yangdu for a 3 pound one.
