- From HI, I would without doubt recommend the 16.5-18 inch Bonecutter/AK/CAK/Ganga Ram/ASTK/M43 models as a true workhorses. (Bonecutter is my favorite)
- From Tora, any of the village or military models would work.
- From the Khukuri Houses it is a little bit more hit and miss in terms of size, weight and balance; and therefore usefullness. If you go with one the "Khukuri Houses" I would stay with some of the tried and true models such as the Jungle 10.5" blade, Bhojpure, Panawal or AngKhola. These are what is considered the working village models, not show or display blades. And even though they are not made with the same specs as the originals, they are tough blades in their own right. (although unnecessarily heavy and unbalanced)
I would stay away from carved handles and lots of fulllers (grooves in the blade) such as the "chirra" models with 2, 3, 4 and even 5 fullers in the blade.
A lot of this depends on your size, what you intend to do with it and how you plan to carry it. Some are far too heavy to carry on the belt but make great car camper blades. Others are nice to carry (small and light) but lack a bit as heavy choppers. There is always some give and take with these models.
Good luck on your search...
