Mason's mitre Mason's mitre A mason's mitre is a type of mitre joint, traditionally used in stonework or masonry but commonly seen in kitchen countertops. In a mason's mitre, the two elements being joined meet as for a butt joint but a small section of one member is removed creating a socket to receive the end of the other. A small mitre is made at the inside edges of the socket and on the end of the intersecting member so that edge treatments are carried through the joint appropriately.

The hand-grenade in its primitive form had become obsolete by the mid-18th century but grenadiers continued as elite troops in most European armies, usually retaining the mitre cap
