The proper Spanish word for mosquito, is actually "mosquito". "Zancudo" is used in some parts of Latin America for all mosquitoes (Venezuela, for instance), and in other parts to designate certain kinds of long legged mosquitoes ("zancudo" means something like "long shanks", and isn't a particularly elegant term).
Anyway, I was a bit underwhelmed with this knife as ESEE's first folder, the name is just a very minor point. I mean, I've got knives with much worse names (Onslaught, Paramilitary, etc.). However, I was expecting something that would tie in a bit better into the looks and materials of the rest of the ESEE line, as well as being made in the US. For some reason, I pictured an ESSE folder somewhat similar to the HEST one.
I'm sure this knife will be good, these fellows haven't put their name on any bad product that I know of, but it just isn't what I expected.
