Roncole e pennati a potatura italiano
Italian makers still offer a wide range of regional shapes. Angelo, Leonelli, Panzeri, Rinaldi and other makers show a wide range of blades in their catalogues. However one manufacturer may be sourcing his tools from Pakistan, as several years ago I came across a manufacturer there who was selling a wide range of leather handled italian blade profiles....
The single edged billhook is known as a roncola (plural roncole), double edged ones as pennato (plural pennati) and square bladed ones, which may also double as meat cleavers, as mannaia (although there are many other regional and dialect names).
Handles are often made of leather washers, but in some areas wooden handles are preferred, and these may be fitted to a tang, or more commonly as scales rivetted to the sides of an extension of the blade. A common feature on many Italian billhooks is an extension of the tang to form a hand guard, c.f. the caulked handle of an English billhook. This is not, as commonly thought in the UK, used to hang the billhook up - some regions have a hole at the end of the blade for hanging on a nail or peg for storage, and a belt hook (gancio) is common in most regions for hanging it from the user's belt.
To combat the scourge of the Fiskars plastic handled brush hook (sold as Gerber in the USA or Wilkinson Sword in the UK), Angelo of Bergamasco have produced their own version, sold as a European pattern roncola (which sells for a lower price than the aformentioned Fiskars)
