Rasps are Aggressive

The biggest advantage to having a wood rasp is that they are incredibly aggressive. Due to their nature, they remove wood at an alarming rate. This means if you have a big project, it can save you quite a bit of time.

The way the tool works is by having a set of very sharp teeth that are also rather long. Unlike a file, where the grooves/teeth are rather short, these are extremely pronounced, and they’re also very sharp.

As a result, they shape wood with a tearing action that pulls apart the fibers and separates them very quickly. This is huge for aggressive wood removal, and saves you a lot of time.

Major Shaping Projects

The time you have a large project to do that requires a lot of shaping of your wood, that’s a good time to use the wood rasp. They’re aggressive, and since they remove a lot of wood quickly, they can help you complete your project quickly.

One of the major issues with carving projects is that they tend to take quite a while. They can also use up a lot of energy. The better the tool you use, and the faster you remove material, the easier the project becomes.

This allows you to do major shaping operations on solid pieces of wood and even laminate very easily. It’s going to leave quite a rough surface behind obviously, simply due to the nature of the tool, but it will remove and shape the wood very quickly.

Wood Carving Applications

In wood carving applications, the best place for the rasp is right after roughing out your blank with a saw. It will remove the majority of the material, and it removes it very quickly, which is why you use it first.

Right after the saw, you need your next most aggressive method of wood removal to get you to the next level. That’s where the rasp does an extraordinary job at getting through this next phase of your carving project.

Use it to break all your sharp corners, round up anything that needs to be rounded over, and start the initial shaping before moving onto finer tools. Those finer tools will remove materials quickly, and they’ll leave a smooth surface behind.
