Notes on my ongoing findings
1) No chopping tools, instead use a baton
So far I think I've pretty much ruled out anything that chops. If it can chop then it's to heavy for ultralight use.
Instead of chopping it's best to take something that will work with a baton.
2) Never use baton with a lock blade
I had a fairly high quality lock blade. It didn't occur to me that batoning would damage the locking mechanism but it does. Will never try that again.
3) bow saw blades rock
One of my most promising discoveries thus far is just how awesome a bow saw you can make in the woods with just a simple bow saw blade and two medium sized key rings. I didn't even need another knife to make the bow saw. I simply wrapped some heavy cloath around the bow saw blade and that was enough for me to turn a green sapling into a first class bow saw. Only three cuts are necessary.
My 21" bow saw is way more saw then I need since it can cut through a 9" tree in seconds, but when you carry just the blade it's as light if not lighter then any option yet mentioned. (will have to post exact weight later) I think with a little practice I will get to the point were I can make a bow saw in under two minutes. Which is way less than the amount of time it's going to save me
3) Coughlin's Pocket Sierra saw works
I could not find a Fiskars pruning at any of the local stores though I'm more certain than ever that it'll be my final tool of choice.
That said I did find a Coughlin's Pocket Sierra Saw. I didn't expect much from it but it actually worked pretty darn well and it weighs a scant 2.5oz without any modification.
4) Linoleum knifes are tougher then you might think.
My experiments using a baton to section and split wood with a linoleum knife weren't that great, but it's almost entirely do to the blade shape. It is far to curved. That said the blades seem to be tougher then I thought. I'm also fairly well convinced that a fix blade knife is the only way to go for spliting wood so I may well end up revisiting the Linoleum knife and reshapping it to a more ideal shape… i.e. like a Sami / Leuku knife.
5) Hand pruning sheers not versatile enough.
I have recently even discovered a post from Ryan Jordan stating that he has on occasion carried a pair of hand pruning sheers so it wasn't a completely crazy idea on my part but I was unsatisfied wit my initial experiments.
I will continue to experiment with different hand sheers and similar devices but these were way less versatile then I thought.
They have an extremely limited range in the size of wood they will cut and were almost no good at splitting wood. In fact my wire strippers were far more effective.
6) Planning on revisiting the cord saw and trying a hand chain saw.
Since I've had such luck making an improvised bow for my bow saw blade I figure I mine as well get in some more practice by revisiting my cord saw and trying a hand chain saw as well. If nothing else the practice in making improvised bow saws will be good for me
7) WILDCARD: Carbide Grit Rod Saw Blade
This blade is really made for cutting metal and ceramics but when I found it at sears while looking for the Fiskars retracting hand prunning saw I figured I mine as well give it a shot.

It too will require me to make an improvised bow saw albiet a quite small one.
I don't need it to do much more then partially cut through a 3" log so I can snap it so I have high ups. What's more if it works it may well be the lightest wood cutting option ever posted here on backpacking light.
Will keep you posted.
