Have been doing martial arts for 30 years (didn't care for black belts) , been in the army (1 year only) and got an engineering degree (didn't give me common sense), and designed a self defense weapon before (no idea how many actually sold). Still think I can do a good job on designing a Kukri which works for me.
What do I need?
Am I a Ninja or a Ghurka who can sneak up on enemies and would always have time for big swings or silently cutting throats? Nope. I'm a clumsy western guy. I'm most likely the one being attacked. Before I even know it the bad guys will have moved in close and then being able to stab will be vital. Still I would like a blade which I can use for chopping wood as well, since this will happen way more often than any self defense situation.
From what I know batoning should be done above the sweet spot and not the tip.
The HI Ultimate fighter doesn't allow batoning at all and its tip points up too much for my taste. Its not an ergonomic angle at which I would stab with a Kukri. Same problem with some of the Bowie Kukri hybrids.
Also I need a guard, in case the other guys knife slides down my blade or I'm too clumsy and in danger to grip too high and into the blade

. I also like to have a tang sticking out of the bottom to strike the other way in case I have that opportunity.
The swedge which I plan will be mostly on an extended (!) tip and thus not close to the sweet spot at all. Batoning should be working as usual.
The swedge takes away metal but the extended edge adds it back. This way the balance should stay the same as in an original shape Kukri. I try to figure out the balance with drawings and calculations before I make some mock ups. The work is far from done but I think I can share some pictures with the general idea later tonight. Might open a new threat for this.
