I recently went to a wood (and Esbit) stove, so my knife choice has changed, carried a SAK Classic and it worked well for everything I asked of it (I used the scissors more than the knife!). I wanted something that could baton/split small pieces, make fuzz sticks, carve and clean trout/grouse.
I looked and looked and finally settled on a Landi PSK knife. Full tang, 1095 steel made from full 1/8" stock. The knife is 6 3/8" overall w/ a 2 1/4" blade. I ordered w/ thin (1/8") scales to save a little more weight. The Landi differs from a lot of other small full tang knives in that the handle size is larger (longer) than most- fits comfortably in my medium-ish hand. John utilizes a flat grind for strength, it comes razor sharp and holds a edge nicely. The spine of the knife is very square and makes using a firesteel very nice.
The knife weighs in at 2.7 oz, the kydex sheath 0.6 oz. I carry mine w/ a neck lanyard (2.5mm Spectra)- I added a small plastic ring so it would break in an advent of a fall (the Spectra is in the 250 # test range). I also added a Fox micro whistle, along w/ a Photon light. I wrapped the sheath w/ 15' of the Spectra (extra guy line, lashing for a debris shelter, etc). Within the lashing is secreted a 3/16 x 2.5" firesteel. I also added a wrist lanyard w/ a double cordlock- this allows me to secure the knife fully in a neck carry (the knife snaps in nicely into the kydex- just an extra measure).
total weight w/ knife, sheath, cordage & hardware, whistle, firesteel and light is 4.7 oz
