For use as a Khukuri buy a real Khukuri. Buy a Himalayan Imports Khuk. Real, Nepali-made Khuk. CS wants WAY too much money for what you get if you pay for the San Mai Khuk.

Granted, the CS Khuk is a very good machete, but that's it. It's a poor excuse for a Khuk. Check out the pics over on bladeforums dot com. Click on the Himalayan Imports link under Manufacturers Forums. You'll find what a Khukuri is supposed to be. The HI products are not cheap display knives. They are not the newest tactical, ninja/nazi/rambo style stainless steel junk. They are real working Khuks that will last you forever. They are guaranteed forever. The Chiruwa Ang Khola Khukuri is even guaranteed for use as a prybar. Try that with CS, Ka-Bar, Windlass Steelcrafts, or Khukuri House knives.
$125.00 to $195.00 will buy you the best Khukuri available. Almost indestructible.
Spine thicknesses of 3/8" to 1/2". Edge geometry correct for heavy chopping. You can get a Tamang knife from them if you want something around 1/4" thickness, for lighter chopping than a Khuk but heavier than a CS or Ka-Bar kukri. They have a full range of knife and sword designs, all made for real world cutting/chopping/working.
See what their customers have to say about them. I personally exchanged many emails and had several phone conversations with Yangdu(the owner) and her sweetness, prompt replies, patience with me, and attention to and care for the customer's needs is better than anything you'll find with any of the big companies.
You owe it to yourself to get an HI Khuk.
I have an 18" Bonecutter ordered. It's being custom made for me with Dhar wood handle and left handed scabbard. When it arrives, I'll post pics and review of it here and at bladeforums.
The HI Khukuris also come with the Karda and Chakma, which are a smaller general use knife, and a sharpening steel(respectively) that fit into the same buffalo hide sheath with the Khuk.
