Nice khukuri Mike. Hopefully John Powell will be along soon, as he is the premier khuk expert. It looks similar to the sirupati, a lighter khukuri. I have one similar to yours. Inside the pocket with a flap may be a removeable pouch. It was used to carry tinder and a flint for starting a fire. The blunt chakma was used to steel the edge of the blade, and also for striking the flint to make a fire. At least this is my understanding.

Here's a pic of mine. It has an interesting all iron chakma.
Edited: I don't think it's a hanshee, as those are most characterised by more curve, and a long narrow curved handle, like the top two here:
