The Petzl Am'D karabiner is great for most uses and thanks to its D-shape it's one of the strongest and lightest locking carabiners out there. The 'D-shape' has the highest strength-to-weight ratio of all karabiner designs. The shape and size of the AM'D is great for most uses, such as connecting a belay device to your harness or as a connector at the end of a lanyard. The D-shape makes it one of the strongest and lightest locking carabiners Petzl makes.

The DMM Captive Eye ensures that in real life situations the connector will never be cross loaded through misalignment. Whatever the captive eye is stitched or connected to it can move freely thanks to the circular hole. The hole can also accommodate a second connector should the need for a rescue point arise.

The DMM Phantom is their ultimate trad and alpine screwgate Karabiner, and when you hold those 42 grams you will understand why! They claim they could have made it even lighter, but didn't want to compromise the handling or strength. As you can see from the specification below the strength is still impressive and the gate opening reasonable for a small D shaped karabiner.
