Got my brother to bring his M43 over today so I could take a picture of both our M43's to compare the older model with the newer one.
Top - my M43, the new longer model by Young Sher
Specs - 20" overall length - 14.25" blade
~~~~~~~
Bottom - my brother's M43, the older model made by Old Sher
Specs: 17.5" overall length - 12.75" blade
The older M43 is significantly lighter weight, and thus more agile. If the kami's could keep the new longer M43's size but get the weight down to about 35oz, it would certainly be a contender for the title of Ultimate Khukuri.
Speaking of which, here they are again with the Super CAK:
