Oval. The semi-circle at each end distributes the load while allowing the rope or another carabiner to shift with movement. Typically these are the least expensive, lightest in weight to include the mini size. The tradeoff is they are not as strong and a little more difficult to clip than other styles, but are is ideal for clipping gear and rack items to the climbing harness.
"D" - Symmetrical. The "D-shape" causes the connecting runners or rope to shift toward the spine side (away from the gate). The spine side of the aluminum carabiner is stronger than the gate. This type will take more shock and weight force than the standard oval. They are easier to clip into runners and anchors points than the oval. This type works well for lead and top rope clipping.
"D" - Asymmetrical. The asymmetrical function provides space for a larger gate opening. This facilitates clipping and reduces weight a little. The asymmetrical has a larger gate opening than the symmetrical, but has less space inside the carabiner. It is also a good choice for lead and top rope clipping for experienced climbers.
