- The longship: The Saxons were one of the first cultures to develop the longship, a type of boat that was ideal for raiding and trading. These boats were long, narrow, and shallow-draft, which allowed them to navigate rivers and coastal waters. They also had a single sail, which helped them to move quickly.
- The windmill: The Saxons also developed the windmill, a device that converts the energy of the wind into mechanical power. Windmills were used to grind grain, pump water, and power sawmills.
- The plow: The Saxons also invented the plow, a tool for breaking up soil in preparation for planting. The plow was pulled behind an animal, usually an ox or a horse, and it helped to make farming more efficient.
- The alphabet: The Saxons also developed their own alphabet, which is still used in English today. The Saxon alphabet was based on the Latin alphabet, but it had a number of unique letters, such as "thorn" and "eth".
- The calendar: The Saxons also developed their own calendar, which was based on the lunar cycle. The Saxon calendar was used to track the seasons and to determine the best times for planting and harvesting crops.
- The musical scale: The Saxons also invented the musical scale, a set of notes that are used to create music. The Saxon musical scale was based on the seven notes of the natural scale, and it was used to create a variety of melodies.
