Thank you all for invaluable input from dear forumites.
I had to clarify this first, I love my Ghopte since I opened the box, saw the knife, and put my hand on it as MauiRob would agree. I'm not whining nor complaining, but just want to know if there's any simple way to go its last inch to perfection.
Thanx to Rusty (and other forumites who posted the same solution), I had executed the idea of mild filing the butt cap slowly, believing it would fit my palm in near future... until mid January.
I had a chance to compare Ghopte to one of my pal's AK of the same. He's a recent HI customer, and haven't shown up to Cantina yet. However he's a frequent customer within a month, surely an HIKV carrier. We put our 12 inchers side to side and looked into them. To my great surprise, his AK, a "pocket battleship" looked like a twig.... half size in width, half size in thickness, half diameter of the buttcap. AK's "sharp" butt did not get into my palm at all! I had developed several ways of smooth grip, mainly as Bruise suggested. It worked perfectly with AK. Thus I came to think if the handle is 1 inch longer between "ring" and buttcap, I'd hold that part not only pinky but also ring finger, it will give perfect grip without spoiling its style. I mean, a 13" Ghopte with same blade, same between bolster and "ring", and 1" extention between "ring" and buttcap.
My current options in mind is;
1. Send it back to BirGhorka via Uncle Bill, for this modification
2. Send it back to BirGhorka via Uncle Bill, to make improved version, to have two Ghoptes.
3. Keep it as-is
Disassemblying it, and stretching the tang is too heavy and risky for me. I'm a kind who disassembly and reassembly a radio, then have some extra screws after that.
Uncle, is either of 1 or 2 works? Can you transfer what exactly I want? If possible, I'll take less misunderstanding way.
firkin, Ghopte is a kind of forward curving khukuri that means "hunchback" as I learned from HI forum. Forward curving khukuri is an old style where modern khukuri like AKs have more angular spine line. I thought that style fit more to small, beafy khukuris. Dave knows much more than I, though.
Ivory handles sound nice, but is there any ivory available nowadays?
