Martindale is probably the most famous maker of machetes and similar knives in the UK. The croc is their logo. Remember, Britain used to have colonies where the crocodile was a common sight.

When, Life magazine ran a profile on author Ian Fleming, one photo showed him reaching for a machete stuck in the sand by his home in Jamaica. I think it was probably a Martindale.

Does your blade have two small grooves along it? The faded word is probably Birmingham.
