There are different ways to cut sandstone blocks, depending on the desired result and the tools available. Here are some common methods:

1. Hand tools: For small-scale or precision cuts, sandstone can be cut manually using traditional hand tools such as chisels, hammers, saws, and wedges. This method requires skilled workers and may take longer than other techniques.

2. Quarry saws: In large-scale operations, sandstone blocks are often cut using quarry saws, which are large machines with diamond-tipped blades that can slice through the rock with speed and precision. This method allows for consistent sizing and shaping of the blocks.

3. Wire saws: A wire saw is a more flexible tool that can cut through irregular shapes or curves. It uses a wire with diamond beads threaded through it to slice through the sandstone. This method is often used for artistic or ornamental carving.

4. Waterjet cutting: Waterjet cutting is a newer technology that uses high-pressure water mixed with abrasive particles to cut through materials. This method is more precise than traditional saws and can create intricate designs quickly.

No matter the method, care is taken to ensure that the sandstone blocks are cut cleanly, with straight edges and smooth surfaces.
