Mitre Blocks are used to cut wood with precision. They give a strong guide when hand cutting mitre joints at a variety of angles, though 45 or 90 degrees are the most typical cuts required. Using them helps to ensure two pieces of material can join together without gaps and provide a smooth and high-quality finish.
Slits are cut into the edges of the box or block to allow for both straight and precise angled cuts. These slits are designed to guide a saw to ensure perfect lines are cut.
