As you see, I am a knife collector too.
I use the full tang knife in winter times.
It left the market and it isn't some thing special. It is a simple and cheap full tang knife. 9,5 cm blade, 168g including the leather sheath.
In my opinion something larger and heavier isn't necessary.
It gives me the option to use the batoning technique if it would be necessary.
In winter times, especially in the end of the winter this could happen.
But even in bad conditions a sharp folding pocket knife would be enough, it simply would take a far longer time to pare some twigs and branches to reach dry wood instead of splitting it.
So, in whet and cold conditions I take this light full tang knife with me.
But most times of the year I let the relatively heavy full tang knife at home!
My standard knife is the Victorinox Climber, 82g, 33 €. It is a very good travel knife, because it contains half a kitchen and the necessary nail scissors too.
In the hands of a good bushcrafter it is a good bushcraft knife. For me it is enough. In all conditions and every where.
I do not really need my full tang knife.
If I would have to replace the Climber one day, I would buy next time instead of this a VICTORINOX COMPACT. (44 €)
The Victorinox Compact is better equipped for the necessities of a hiker than the Victorinox Climber, and with only 64g the Victorinox Compact is lighter!
It includes a stainless steel needle to open blisters and a ball pen!
Because you can't put a normal needle in your pocket without a tough container,
together with the pen the Victorinox Compact saves here around 40 g and it is 18g lighter than the Victorinox Climber!
So, together it saves around 60 g if you compare it with the Victorinox Climber, a weak standard plastic pen and a needle in a small container! And you have all you need attached with a line to the man!
THE VICTORINOX COMPACT IS THE BEST TREKKING KNIFE OF THE WORLD MARKET!
For the second person in a team the Opinel Carbone No 7 folding knife is the optimal light bushcraft and trekking knife in dry conditions. Its 10 cm handle fits very well in the pocket and in the hand of an adult man. The 7,7 cm blade is incredible sharp and very easy to sharpen, even with nature stones picked up somewhere.
It is incredible light: Only 35 g !!!
And it costs only 9 €.
Is is the best foldable cooking knife i know and it is a very good carving knife!
For children I recommend the Opinel Carbone No 6 or stainless steel, Carbone No 6 is easier to sharpen. 27 g, 7,2 cm blade. The handle doesn't fit in the hands of adult persons.
The Opinel Carbone No 8 , 45 g, 8,5 cm blade doesn't fit so good in the pocket. I prefere the No 7.
(The No 8 you can see in my foto I usually have in my kitchen bag for car-camping.)
I prefere Carbone steel, because it is a bit stronger than stainless steel and easier to sharpen. But for those who prefere stainless steel: Opinel offers this too, in the same sizes.
