I may be blowing hot air here, but here goes... I don't think that "little khukris" i.e. those with an overall length of 12 inches or less, are really all that useful. The 12 inch sirupati is considered by many to be a great martial arts weapon, and possibly has some kitchen use as well. No argument there. But considering that in Nepal and the surrounding area, they use khukris for EVERYTHING, you can see where something that small isn't going to be too practical.
Small, of course, is relative. But a khukri has that unique bend in the midsection that, while giving tremendous power to the larger blades, seems like it would get in the way of the smaller ones. I don't own a 12" sirupati, but I have seen one. As a utility knife, I just can't picture what it's good for. There isn't enough uniterrupted blade edge to really get you anywhere. Imagine you're out camping. Try carving a roast with it, dicing vegetables, or cutting up some tinder for the fire. Can opener, sure, but otherwise...? I think (personal opinion only) that the khukri has some inherent design features that just make it impractical below a certain size. If you need a knife with an overall length of 8-10 inches, get a Spyderco. if you need a serious working survival blade to build shelters, take out shrubs and other gardening, "remodel" you kitchen, etc., then get a khukri.
You'll be glad you did.
