Modern Billhooks 2
As well as commercially made billhooks, one oftens finds 'specials' that are made to order, or owner modified from another tool (e.g. a machete). Occasionally 'prototype' new billhooks (or billhook shaped machetes) can be found...
A prototype designed by Benjamin Bouchard of the Baryonyx Knife Co in Hampden (ME) in the USA (aka as FortyTwoBlades on various knife forums) - it combines a billhook blade on the back of a 16inch machete blade - see the spec below...
I found the image for this billhook on a knife related blog. Although the handle is similar to the one above, it is not by the same maker.

(I have found several images of my billhooks from this site there, so assume he will not mind me reciprocating by posting from his site).
