Veeteetee who posts on the Finnish/Earlier Scandi Axes-Knives sent me a study done in Finland I think in the 30's where Birch tested out as well as Hickory for axes handles. I do not have the email he sent me anymore. I wonder if it is because the Birch trees in Finland are exposed to hard winters? I ask as years ago we did work with Klepper Folding Boats, made in Germany. Mr Klepper used birch rods as the frame of the boats, but only from Birch trees that grew on the North side of the hills in Finland, as their growth rings were closer together, smaller? John
The Nordic birch species are stronger than our paper birch and are more akin to yellow birch, though I'm having a surprisingly hard time finding specific species in English. I've read that those used for axe handles were especially selected from shady locations that caused them to be even more slow-growing and dense. Yellow birch isn't as good as hickory is, and there's a reason why so many Nordic axes have large eyes and/or collars. I'd be very surprised if it was able to test equal to hickory. But depending on species, birch can be a very strong wood, though prone to rot. Scythe nibs in the USA were traditionally birch since the wood would crush rather than split if over-tightened.
