My mistake. 'köttr' declines like 'völlr', not quite the same as
'skjöldr'. Sorry about that. The difference is in the dative
singular and nominative plural:

sg. pl.

N köttr kettir
A kött köttu
G kattar katta
D ketti köttum

N skjöldr skildir
A skjöld skjöldu
G skjaldar skjalda
D skildi skjöldum

Likewise in Modern Icelandic, except that nom.sg. -r is expanded to
-ur, and acc.pl. köttu > ketti; acc.pl. skjöldu > skildi--but the old
acc.pl. survives in the set phrase 'koma e-m í opna skjöldu' "to take
someone by surprise, catch someone with with their guard down"; Zoega
"to attack in the flank (from the left)".
