I took a Buck 110, Randall 15, Leatherman tool, and a Laguna hawk. The hawk got left home after the 2nd or 3rd trip out of the wire, wasn't using it and wasn't worth the weight as others have mentioned. I fear your kuhkri may meet the same fate. Then again, I saw a guy toting a full size sword on his armor so to each his own.
Also, is your unit good with you taking something like that? Some are, some aren't. I would know that before I dropped the $$.
In all my time overseas I think the only time I saw anyone with one were actual ghurkas.
All that said, if you can take it and want to then drive on. A lot about sleeping well at night in those places (for me at least) was having things I had faith in working if I needed them.
