Which grammar structure does this sentence fit into?


Which grammar structure does the following sentence fit into?

> あのナイフは、パンを切るのにつかいます。

I translated it as "That knife is used to cut bread". However, I can't
understand the 切るのにつかいます part. The closest I got was that you can use に ＋ V ます
to express purpose, such as 勉強しに来ました(I came to study). But these examples did
not use the nominalizer. What structure is used in this sentence?
