the stick tang as you call it is the nepalese way of making them and they are hand bashed out on the floor of a workshop. with a buffalo horn handle glues in with crushed beetle and pine resin.
the full tang are indian copies and are made differently with a wood handle and rivets
the key difference is the indian ones are frequently bashed out of any old steel for a little as a dollar each on a mass production line. the nepalese ones are made by a kami with a workshop team and each blade taking a day to produce for around 10 dollars. the blades are hand tempered to give a flexible back and sharp edge.
look up himalayan imports or kukhuri house for more info.
have a feel and see what you like as the handles are often carved differently and for smaller hands than westerners. you will probably want to play with the blade and polish it up a bit as they are made from lorry springs or the ends of rail lines and will rust.
they are a different way of working though and if you arent used to them then often a more conventional blade like a cold steel or kabar kukri might suit your tastes better as they are more a machete with a heavy end whereas a proper kukri is loke a long axe I guess
