In The Lovely Bones, what did Mr. Harvey cut Susie's body up with? A straight razor? A knife?

The
torturous and murderous Mr. Harvey cuts up
young Suzie's body with a knife. He dismembers her in
order to hide her body.
The rape and murder of Suzie is made all the more horrific by the

dismembering of her body, as Harvey slices her body with a knife. He violates her in
life thrugh
rape and in death through the dismembering of her corpse, and
this makes her murder even more
particularly gruesome. Harvey mistakenly
leaves her elbow behind, which is an immensely blatant
mistake for a serial
killer to make. Due to his carelessness, a neighborhood dog finds the poor

girl's elbow, and this eventually leads to an intense and complicated investigation into
Suzie's
death. If Harvey had not cut up her body with the knife, it is
possible her death would have
remained a tragic
mystery.
