The destinctive Scottish sword guard with it's down-turned terminals found on the Half-lang and Claidheamh da làimh swords, suggests that the Scots might have favoured blade-trapping techniques using the terminals to 'lock' an opponents sword.

Down-turned terminals of the Half-lang

The Half-lang isn't identified with the Scots as much as it's two-handed cousin, the Claidheamh da làimh, despite it being a very popular weapon.....
Sources refer to large quantities of half-lang's being supplied in medieval Scotland and guards for halflangs being constructed as late as the 16thC.

"Thay brocht … cccc (400) half lang swordis"  
"Ane thowsand haiflang swordis and haberjouns"

There seem to be more statistical accounts regarding this type of sword rather than the two handed version during this period and with such large quantities circulating in Scotland, could it be that many historical references to great-swords, claymores and two-handers actually refer to mis-identified half-langs?

Was the 'half-lang' and not the Claidheamh da làimh, the favourite big weapon of choice for the Scots?
