Translation:The cook is cutting the meat with scissors.
Adreas, Good point! In Am Eng, the larger scissors used in a kitchen such as for cutting out rib sections on poultry or dividing the backs and breasts into smaller pieces are called "kitchen shears". Likewise, those for trimming plants, such as roses, are called "pruning shears". Maybe in Bokmal, there is a different word for those heavier duty variants. 12Jul17
'A scissor' is wrong too. It's a pair of 'scissors' (as in two blades). Like trousers, or pants, because there are two parts to them.
In other questions where scissors was used the answer was a pair of scissors but in this sentence you say you said I was wrong to use a 'pair of'. Actually I had wanted to use only the word 'scissors' although I would rather have only used 'scissors'. When you marked me wrong in the other cases when I only used 'scissors', I assumed you used 'a pair' in all cases. So someone tell me why I was wrong in all cases.
