I like both, but I do feel Marttiini are neglected in the US. Here in Finland,it's a different matter of course! But pricing would surprise Americans, both Mora and Marttiini cost more than they do in the US.
No doubt about it, the traditional red wooden handled carbon Mora is a fine everyday knife, but don't forget the carbon Marttiini either. Costs a little more but its traditional birch handle is fatter and more grippy than the Mora's. other Marttiini knives I have in stainless have been well made/finished and provide good service. The rubber handled models are particularly useful.
Then there's the sheath: Up end any Marttiini or most other Finnish puukkot for that matter and give the sheath a good shake, almost certainly the knife will stay in as they have a snug secure fit. Try THAT with a red Mora, out it will come.Not much chance of dropping your knife and the dangler style of most puukko sheathes mean you a sit down in the car,or having a rest without getting a nasty poke in the ribs from a knife handle.
Both these knives should be in knife collections everywhere!
