Mattucashlass
Appearance
A mattucashlass is a type of dagger worn concealed in the armpit and primarily used for close combat, part of traditional Scottish male Highland dress.[1] It is also referred to as an armpit dagger[1] or a sleeve dagger in English. In Scots, the alternative name skene-ochil or skene-occles can also be found.[2]
Etymology
[edit]The term mattucashlass derives from Scottish Gaelic: biodag-achlais[3] (Scottish Gaelic pronunciation: [pit̪akˈaxl̪ˠɪʃ], biodag meaning "dagger" and achlais "armpit") presumably via the dialectal by-form miodag, which is attested in Shaw's 1788 Galic and English Dictionary.[4]
It is also known in Gaelic as the sgian-achlais (sgian meaning "knife"),[5] from which the Scots term skene-ochil or skene-occles is derived.
