An agricultural tool shaped like a pickaxe, with an adze and chisel edge as the ends of the head. I remember reading the word ‘adze’ when I was a child, and looking at a black and white drawing of a man wielding one. The spelling of the word dazed me.
‘In battle they wielded heavy two-handed mattocks.’
