All that said I would still rather have a multitool, a sheath knife and a axe .............the key is the sheath knife as this makes carving easier - Puukko, is a Finnish names and a corruption of the word Carving - so a Puukko is a carving knife.
Which brings us onto Combo's - George Washingdon Sears AKA Nessmuk, the great grandaddy upon which many pin their wilderness asperations used a trinity of cutting tools - a double bited hatchet, a sheath knife (the nessmuk knife - which I believe to be a broken down butcher knife) and a folding pocket knife. If we read the greatmans writings we soon learn that the axe was used for fire wood prep and a little butchering - the Nessmuk knife was for skinning and game prep (although he does mention eating his beans with it too?) and the pocket knife was used for food prep and whittling ect .............. obviously a tried and tested combo which worked for him - but how many of you will ever skin a elk? Nessmuk while a great outdoorsman was primarily a hunter - not a bushcrafter or survivor - and I bet you pound to a pinch of pooh if Nessmuk were alive today he'd have a multitool too!
"Ah but the great Ray Mears ALSO uses a combo of sheath knife, SFA (Small Forest Axe) and a folding saw" - I hear you say and rightly so. Without a doubt this combo is copied by almost every bushcraft instructor in the country and every aspiring woodlore wannabee - and why? Because it works?? Or because its percieved to work by those with less experience?
A good four inch sheath knife will carve beauiful and useful objects (so will a multitool but less comfortably), the axe will help in the firewood and shelter construction and the saw means we can process wood for utility, use safely without needing to worry or understand any elaberate knife skills ............a good trio?
But say we needed to strip out the cables of a downed plane to make snares - or free up a frozen spark plug on our snowgo?? Would a woodlore knife or SFA be much use?
I know lets carry 4 cutting tools .......... but errrrrrrr isnt that over kill?
Another thought, in the frozen north (and Lincs a short while ago) where reindeer meat is the staple a longer Leuku (butcher) knife is most common - as with the mountain men - this knife was a combo in itself part hatchet, part butcher knife and part fighting knife - a wilderness knife! Favoured by such well travelled folks as Lars Morsen, the saami and most native peoples around the world a bigger camp knife is possibily more useful than a small one. The saami and many scandinavian outdoors men often carry both a Puukko and a Leuku on the same belt or sheath this combo ticks many boxes!!
Lastly ponder old Les Hiddens, the bushtuckerman, his cutting tools were a small pocket knife something like a stockman and a bombproof old army Golok ........ no fancy saw or knife in site!! This is a fact I've also found with all genuine outdoors folk who live and work in the wilderness their choice of tools are usually more practical and less aesthetical.
But you and I dear reader, well we arent famous 19th Century hunters or 21st century TV presenters so what should we carry??
Well personally I say carry what you like as long as you can use it - dont model yourself on Nessmuk or Ray Mears or Les Stroud - let your experience and your skill dictate! But equally dont end up walking around better armed than the average viking raider ......... you'll look stupid and bring ridicule upon yourself and your peers!
For me my perminent travel companion is my Leatherman wave, this goes everywhere with me now - if I am out over night I will add a scandi forest axe for fire wood prep. If I am travelling or running courses where I need to do fine carving then a scandi style knife is carried (I have a cracker made for me by a friend) - in my base camp bag as a back up or for when I dont have the axe I carry my Saami double hunter - although if it wasnt so stupidly expensive I'd recommend the Fallkniven A2!
Ultimately people my point is think for yourself - dont just copy Nessmuk or Ray Mears because you lack knowledge or skill. More importantly regardless of which cutting tool you choose learn to use it properly - 100% effeciency is your goal for in the right hands any cutting tool will produce the goods!!
And if you think about this - if you practice using your tools and you understand what you need or want them for you will realise two things.
Firstly, no one tool is good for everything but secondly and more importantly the knife and axe you have are as good as the £200 ones your looking at online or at the gathering/fair/market - understand that and how to use your tools and you'll save yourself time and a lot of money!!
