Cuch this is a rather long standing argument among knife knuts of any ilk.
I have long been an upholder of the rat tail tang......
There's not much doubt that in the beginning the rat tail tangs were invented(?) to save on the so very precious iron.
I have heard it said that in the very beginning of what we call the
"Iron Age" that in many places iron was a whole bunch more precious than even Gold!!!!
I will concede that the chiruwa or full tang may be a
tiny bit a very Tiny Bit stronger, but it really doesn't offset the comfort of a rat tail tang.
Besides the rat tail tang at the intersection of tang and blade is almost a full tang anyway and on a blade the size of a khukuri I can guarantee you it is plenty damned strong enough!!!!
And along with that, when was the last time you done any work on the handle end of a knife?
The full or chiruwa tangs are good if you plan on having a hammering base like the H.I. AK Bowie, but the ha'il of it is it would be easier to hammer with the spine side of the knife.
It actually has more area and you will be able to pound harder with the leverage.
I will stay with the rat tail tang wherever possible with the knives
I use. Thank you very much!!!!

I think the only full tang using knife I actually use once in a while is my Busse E-BM and most of the time I would rather have one of my khukuri's than to carry the Battle Mistress.
The BM is a little better whittler and is the only reason to carry it, makes a pretty good drawknife too.
My Marble's Woodcraft and Fieldcraft, my 52100 ball bearing steel hunter made by my bud Ray Kirk of Raker knives, my Ronnie Foster hunter, 99% of all my khukuris (30 some odd) All have rat tail tangs!!!!
