It's a pre Great War design although the early ones had slightly different proportions to the hilt. They were still being made at least into the 1980s by Martindale.
"Matchet, Rigid handle, NSN 5110-99-120-9963"
The Australians made a version with a canvas sheath and the Canadians one with a better shaped grip, Collins in the US made at least some of theirs
Apart from the obvious jungle use they were issued to all Bren and Vickers teams to clear fields of fire.
