Conflicting renderings in Part II, ch.2

I am directing my thread to someone who reads Crime and Punishment in Russian. I am teaching a small adult education class, the members of which are using different translations. Today toward the end of Part II, ch.2 Coulson translates a sentence as follows: "He felt that in that moment he had cut himself from everybody and everything, as with a knife." Another translation substitutes "as with a scissors" for "as with a knife" and a third translation omits any reference to a cutting tool. If you can locate the passage in question would you confirm for me what the Russian text says.

It says:
«Ему показалось, что он как будто ножницами отрезал себя сам от всех и всего в эту минуту».

Which means (exaxtly as written):
It seemed to him that he had some sort of cut himself away with scissors from everybody and everything that minute.
