So,
I realized I never followed up here.
I’ve settled on some pretty good UL solutions for processing wood for my wood gas stove for winter camping.
1.89 oz knife

1.2oz bow saw blade

== purpose built ==
The primary reason for these tools is processing wood for my wood stove for winter hiking / bike touring and camping.
They are admittedly not necessities as my wood gas stove can burn smaller sticks and twigs for cooking.
However since I also use the stove for warmth and light I felt I can justify the extra 3.09 ounces.
I will not be using these tools every night, just when I have the time / energy or need dictates
They will certainly come in handy when wood is wet.
In short… This is 3.09 ounces dedicated to fun and better enjoyment of the winter camping experience.
== the knife ==
The shape of the blade is inspired by the Leuku knife, also sometimes called a Sami knife. It is however much smaller then these knives which were usually made from truck leaf springs.
Unlike the blades that inspired it this blade is much to light for chopping action and so primarily will be used with a baton.
The curve of the blade is specifically designed to put the fulcrum as far out toward the tip as possible so when hitting the tip with a baton the energy transfers directly into the wood and not back into the handle.
If the fulcrum were near the handle then when you hit the knife tip with a baton it would transfer energy back up into the handle. This is how hilts get broken.
== materials ==
The knife is made from an unconventional source. A scrapper / putty knife.

I used this material for it’s durability as the primary use of the knife is splitting wood with a baton.
I’m completely confident it won’t break, worst case scenario is it will bend. So far it has been more then sufficiently Strong enough to take the abuse of batoning.
In sharpening it I did get it very sharp. Sharp enough to slice through a sheet of paper anyway, but I’m not sure how long it will hold this edge given it’s stainless steel and not tempered/ hardened like a normal knife.
Fine sharpness is however really secondary and unnecessary to the knifes splitting power.
That said it can be used making feather sticks and food preparation which it seems to have no problem with.
Will see how it keeps its edge over the long term.
== two specialty knives vs. one all purpose ==
So… The idea behind this knife is that it’s lighter to carry two specialty knives then one all in one wonder.
In fact I question weather any knife can handle the range of activities from cutting wood to doing more detailed work like food prep, whittling, etc.
Right now I’m also carrying a Micro-leatherman which I’ve always carried.
I do question weather I’ll even need it with this new knife. The only other thing I really use on the leatherman is the scissors and I could potentially put some ultralight folding scissors in my emergency kit with my sewing thread.
== bow saw blade ==
First of all the blade does only weigh about 1.2oz with the two key chain rings I use for quickly improvising a bow.
Secondly it requires actually only two cuts and a couple minutes to improvise a good bow for the blade. This is an excellent example of how skill and experience trump gadgets. No Sven saw or Wyoming saw is necessary.
Some might call this a bush craft approach. Indeed I once saw a video of Ray Mears carrying a bow saw blade in his “billy can”.
What’s more the bow itself only weighs about 7-8 ounces so it’s really not a big deal if I do decide simply break down the saw and carry the bow with me as well.
I don’t suspect that this is the sort of tool I’ll be using every night, but since the blade is only 1.2oz and the gives me the flexibility to take or carry the bow I needn’t fret over the issue. It’ll work itself out over time.
== sheath ==
No sheathes yet.
Recently I’ve just been wrapping them in some plastic which works fine, but isn’t sexy. The bow saw blade can also roll up in a larger bottom pot (i.e 5″ diameter) but I do have a nice place to store it unrolled.
Am thinking about using automotive plastic to make the knife sheath instead of leather as it’s lighter / thinner / tougher.
Will post again when I’ve created the sheathes.
