When cutting plywood, it is essential to use a fine-toothed saw blade and ensure that the teeth are sharp. Additionally, you should use a straight edge or guide to keep your line of cut even and consistent. This will help prevent chipping by making sure that the saw cuts in one smooth motion instead of jerking around as it moves through the wood. It's also important to make sure that the blade is at an optimal angle when cutting so that it won't gouge into the wood too deeply, which can cause chipping. Finally, if possible, try using clamps or weights on either side of your cut line for extra stability—this will further reduce any potential chipping due to vibrations in your saw blade while cutting.
