Out of the Rinaldi Calabria heavy duty axe, Trento felling axe, Cadore axe, and the Italian racing axe, which do you think excels at felling a tree? Why? The racing axe with the 6lb, 3.0oz weight, seems like it would be a beast. I want something that makes the pieces fly, haha. Gotta birthday coming up, and the wife wants to know what I want.
