A saber is a type of curved sword with a single edge.
You might see people using sabers on horseback or during historical reenactments. Sabers are also used as a symbol in some cultures, like the saber-toothed tiger that's an iconic image from the Ice Age. In military history, you'll often read about cavalry units fighting with sabers. But if someone says they're going to "saber" through their work, it means they plan to make fast and efficient progress, using a single edge or approach to get things done quickly.
A light sword, sharp along the front edge, part of the back edge, and at the point.
To strike or kill with a sabre.
