iPhone 5 aluminum back prone to scratching?

User sharingan_sasuk at the U.K. Overclockers forums conducted a test using keys and the SIM card tray of the device.

He took a Liquidmetal SIM card tray pin to his black iPhone 5′s aluminum back, and with a set of keys he scuffed the “chamfered edges.”

The conclusion was that scratches can be made very easily.

The user also posted a photo as proof for his claims.

In addition, according to a Pocket-lint review, the edges of the device become worn after being used for a short while.

However, various tech sites write that this may be a normal consequence when scratching anodized metal with a sharp object, so it shouldn’t be regarded as an issue with the new iPhone.
