Dovetail joint type of joint is used in box constructions such as drawers, jewellery boxes, cabinets and other pieces of furniture where strength is required. It is a difficult joint to make manually, requiring skilled workmanship. There are different types of dovetail joints. The joint is strong especially when used with glue. The angle of slope varies according to the wood used, purpose of joint and type of work. Typically the slope is 1:6 for softwoods and a shallower 1:8 slope for hardwoods. Often a slope of 1:7 is used as a compromise. However, a different slope does not affect the strength
Mitre of a synod of bishops. During the 18th century (and in a few cases the 19th), soldiers designated as grenadiers in various northern European armies wore a mitre (usually called a "mitre cap") similar in outline to those worn by western bishops. As first adopted in the 1680s this cap had been worn instead of the usual broad-brimmed hat to avoid the headdress being knocked off when the soldier threw a grenade. 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
