Hi kentjagman.
You would have to remove the rear bumper.
The chrome strips are secured by metal clips on the rear.
There are lips at the rear of the chrome blades that pass through a slot in the bumper, the lips have a slot and a metal clip is inserted into the slot from the rear
The only way to remove the chrome blades without breaking them is to remove the bumper and remove the metal clips believe it or not!
Here's a link to a PDF about Rear Bumper Removal:

Hope that helps.
Take care.
