P.P.S.
Living very remotely,and connected to the axe-forging community by internet only,i struggled over the years with very variable success.
One of the designs that i always found very attractive is a fairly common Scandinavian hewing hatchet that i especially like in Stefan Ronnquist iteration.
After many years,and many tries,a couple months ago i came up with what i probably like best so far(still Very far from the original though).
It's a very small tool,maybe a pound and a half,but even something that small can Really challenge a guy struggling in the dark,without relying on some solid knowledge or advice from a more informed,experienced smith.
I'd love to forge a Piilu some day,but quite possibly may never get there,as i may be running out of physiology to work the mass of steel past certain weight...

And Piilu-like tools have that Very intimidating mass at the blade.
As you practice forging,please pay very close attention to doing it in such a manner as to not damage any part of yourself.It sounds trite and self-evident,but it does take some effort to not do careless stuff,in the heat of the battle you may say.
I'm paying the price now for all the cavalier things i've done at the anvil,and the ultimate price would be inability to forge at all(and i'm where i can actually see the end...
