Everything can injure you.

[Pikman]

Everything can injure you.

I will post an item. The next poster will describe how this item may inflict harm upon someone, and then post a new item.
For example:

Pillowcase.

Can be tied around your head, causing you to suffocate.
Wax paper.

Can give you a big paper cut and infect the cut.
Telephone.

Etc.

All right, easy one first:
Stairs

You hang yourself with it.

Dark Matter. Blizzy wins.

[Brainwasher]

You can get lost in dark matter and bump into something in space- time.
Also, can't dark matter absorb the light from your cells, making you blind and harming your skin? Maybe, but I can't quite place the name with the face of dark matter.

The chain breaks loose as you are cutting. It shoots up toward your face, and it leaves a three-inch gash. Sadly, the doctors are not able to save you.

Pizza (I have a good one for this.)

[rambo5252]

Hmm as you scarf down the pizza like a vacum cleaner a peice of pepperoni flies off cloging your air pipe, then as someone performs the hiemlick(sp?) menouver they crush your ribs and one punctures your heart.

A snowflake.
