Great thread topic Northern as this really is the key issue for me.

Like you I think the whole thing is best dealt with by adapting to your intended environment - sort of selecting from a tool box.

My most common trio has been a swiss army champ...a benchmade Walter Brend lock knife and an 8 inch Frank Vought Amazon which is very similar to a FSH.

I do also carry a folding pruning saw and Leatherman Secaturs if the circumstances require....and a Gransfors Woodsman Axe if need be.

The Vought might now be replaced by either a FSH or a Basic 9 or DFLE or DFCG. The Gransfors has been swapped in the past for a C.S. Carbon V Kukri but could be swapped for a FBM or NMFBM since discovering Bussekin knives.

The lock knife has sometimes been changed for a smaller fixed blade...a Scandi Bushcrafter or a Bud Neally Kinzhal.

Now there are more choices to pick from but the trio system is basically still followed.

Realising though that you don't need so many knives as you can only carry a few at any given time makes me conscious of whether I should own more "just for collecting". Especially when you realise how much is invested in "draw queens" instead of maybe a great Wilderness Expedition.
