Ever thought about a khukuri? The 12-15 inchers (12" Ang Khola, 13" Pen Knife, 15" Sirupati and British Army Service from Himalayan Imports) do the job of axes while packing quite light, have a steel (chakmak) and a small knife (karda) in the scabbard too. Hard to beat if you ask me because you do not need to carry axe and larger knife. I also have a 16.5 khukuri from HI that weights 23 oz - shelter building with this knife is fast and easy. The bulky scabbard however could be replaced by a homemade one from kydex. So my combo would be
1. SAK outrider (like the rucksack but with scissors and phillips screwdriver)
2. 16.5" HI chiruwa Ang Khola Khukuri or if I have to pack lighter 13" HI Pen Knife (pics below)
for "conventional" survival type blades I like the
Schrade BT01 (has a sawback that actually works and a good sheath with pouches but is not a very good chopper due to the hammer and claw at the end of the handle - if you want a knife with many features - here it is)
and the
Fallkniven A1 (a good and relieable "prybar-type" knife made from VG10)
If I could only pick one as a camp knife I would take the HI Pen-Knife (bellied enough to chop, straight enough to stab, wide enough to dig) - and as you mention self defence - I surely would not like to be on the receiving end of a khukuri...
