I found a used 25" Kobra made by Sanu. I've been using it to whack blackberry growing around the springhouse. That extra length gives me a little more protection. I've accidently hit the tip on a stone and while it doesn't push exactly in line with the edge, it is still sharp. Oh and it is a "balance" khukuri too. Like Steely says, this is a slimmer blade design and isn't really made for major chopping duties, although it can fill in in a pinch. It seems great for working with shrubs, trimming branches and general plant work due to its slimmer blade and design. I've noticed that you seem more defense minded and, although this is a light blade, the Kobra is able to "reach out and touch". I believe some have used it in the past in their martial arts training. I like it well enough for what I use it for and many others in the past found them excellent for their uses. A Search in the Archives will get you lots of reviews and personal opinions. The only thing about the 25" Kobra is carrying it. Wear on the belt is fine if you're walking on flat ground but will require different attachment for any other carry. The scabbard drags on slopes at times while working the blackberry so I don't wear the scabbard for that anymore.
Here are the specs that I got off of this Kobra FYI:

19 11/16" Blade
