Query: Lightweight and sturdy

When i ordered this product I thought it was metal and was scared it was going to be heavy on my keychain. I have never used this in an emergency and that is great but this is lightweight, looks very sharp, safe and sturdy. Would give 5 stars but don't know if it actually will brake a window but probably as you can not push the front down by hand takes some force.
