a good first khukuri depends on what you want it for

or what you think you want it for, cause once you have it, you'll want something else to do the original job, and the first one for another job. and soon you'll have a floor covered in wood, horn, steel and leather.
for self defence, the 12" sirupati is quick but agressive. for general small chores like light branch clearing and such, the 12 ak is very handy, but if your going to be doing any significan work, the larger angs will take immediate presidence. 1 chop from an 18" ang is equal to about 3 chops of a 12" on a really thick branch.
theres a lot of variations of each khukuri, to fit personal prefences and specification of task. your basic 2 models (or so ive reasoned out) are the sirupati, and the ang khola. these two models come in the widest viraiety of lenghts, and are the basic lines of what the design needs to do.
the ang khola is thick and heavy, with a single fuller near the head of the blade.
the sirupati isnt fullered at all, and is reletively thin (from spine to blade), but do to it not being fullered can take a massive beating without feeling like you need to go easy on it.
most of the other models are variations of these two designs, the bgrs being a heftier version of the ang with a more forward balance, the foxies folly being a more forward balance with a broader curve, but double fullered to take off some of the weight so you can handle the broader blade.
the chitlangy and khobra are variatonis of the sirupati, one fullered to lessen the weight, the other thiner from spine to edge to acheive the same effect.
all aspects change how the khukury handles, and how it handles will vary from user to user, from frame to fram.
name a model that sounds interesting, and we can tell you what it feels like, and what we think its good for
