Cascrom

1843, James Logan, The Scottish Gaël; Or, Celtic Manners: As Preserved Among the Highlanders, 1st American Edition, page 309, That excellent instrument the cascrom, literally crooked foot, a kind of foot plough, which the Highlanders can manage with great dexterity, and which is too little known,* is still used in mountainous districts, and, from its excellent adaptation to the culture of rugged and steep hills, where a plough cannot be used, is not likely ever to be superseded by any implement.

1866, The St. James's Magazine and United Empire Review, Volume 16: April—July, page 90, The other was the “cascrom,” a very old Celtic implement, intermediate between the spade and the plough.

And so complete was the carnage within the gloom of the corrie that never a man of the erewhile friendly crofters returned to work the cascrom within the township of Achnashee.

The cascrom, or foot-plough, was at this time unknown in Arran.

The ‘cascrom’, or crooked spade, was the most important tool for agriculture throughout the Western Isles and major parts of the mainland Highlands.
