How do you like the Hankalas ?
Are yours made of Silver steel ?
Yeah, they're silver steel or 'hopeateräs' as it is called in Finnish. High carbon stuff (about 1 ~ 1.2 % ), takes a very good edge and holds it more than well enough for me.
As for the Hankala puukkos... well, Jukka Hankala is certainly one of the most skilled bladesmiths in the whole world and a true master when it comes to puukkos, so yeah, I like them a lot.

Almost too pretty to use - but just almost. For those so inclined, he works with some modern 'supersteels', too.
Those knives look interesting, but i would be afraid of my hand slipping on to the blade, i assume this does not happen or they would not be so popular.
I assume the tip does not snap either?
Actually i remember a ship that came into our harbour (we are a port city) and there were a bunch of guys all working on the ropes on the boat and everyone of them had this kind of knife either in their hands or on their belts...
The hand really doesn't slip when one is careful, as one should always be around sharp objects. It's also a matter of using the right grips for the right jobs - for strong stabbing and thrusting type of moves with a puukko, one should support the butt end of the knife with the thumb or the palm of the hand, so the hand doesn't slip on the edge. Perhaps it is telling that for the decades that I have used a puukko with no finger guard, I have never had my hand slip on the edge.
The tips on puukkos are pretty tough, but they do snap if you really start prying with them. The tip is for carving and puncturing, but not leveraging. Usually though, broken tips on puukkos are a result of folks getting bored and setting up a knife throwing competition, which rather too often results in broken tips for obvious reasons.
Maybe that was a Finnish crew on that boat you saw. Puukkos and similarly styled Scandinavian knives like Moras are everywhere here. Puukkos make great tools, and they do work as weapons too if one is so inclined, but that is not their purpose, so finger guards and such are left out.
