Clem ,i would try as many as possible before you make a purchase.
Knives are a very personal thing and as ChrisKavanaugh quite rightly says "My knife isn't your knife".
I used to favour larger knives with clip points as that is what i started out with (my first knife is on the left)
I liked to carry a large fixed blade and then a smaller folder like an Opinel N0.8
When i started to use an axe ,the large knife was replaced with a smaller fixed blade which is what seems to be popular at the moment in bushcraft.
This is the way i have went.
An axe ,a small fixed blade and a SAK.
If i had to use only one knife i would probably go back to a larger fixed blade.
As i said ,a very personal choice.
Cheers
RB
