This is a wild-wild guess. 'Hanskat' is a Finnish colloquial for 'gloves'. It is derived from Swedish (swe 'handskar'), as also is another colloquial Finnish word 'hanslankari' ('helper, labourer', swe 'handläggare' = handler). So, I think that 'haskat' can in poetic-colloquial language been used in the meaning of 'helper', taking additionally into consideration that it is only human beings (as far as I know) that can be bilingual.
