for most people, khukris are a bit awkward in the hand at first, and many wind up cutting themselves, blade twists or glancing blows, sometimes seriously (typically shin injuries). once you get the feel for them they are awsome blades.
it sounds like you are looking for an EDC type knife. i'll probably get flamed for this, but one of my best and most durable knives is my Becker Necker. there i said it. lol...

seriously, i wrapped the handle with 6' para-cord for more comfortable grip, and have done most everything with it. for cuttin saplings i have batoned through 2"-3" saplings, skinned deer and quail with it, dug roots, and more. it's a sturdy blade that holds an edge and field sharpens easily.
slipped under my shirt it is not obvious to the average person. i enjoy survival arts also, with 6' of paracord on the handle and lanyard, i also have another
6' knotted up for the sheath lanyard for a total of 12' of paracord. with a Ranger band around the sheath that holds a mini Bic lighter, that covers fire making. use your imagination for your needs...
worth a look...
