What are the advantages of a sharp log splitter wedge?

Sure enough, you’re taking a lot of effort to sharpen the log splitter but do you know the same advantages?

We will cover those below.

When the blades of the log splitter wedge are sharp, the logs are easy to split. Moreover, you can split them into the required size. That way, you will not have to perform the splitting operation on pieces of the same log repeatedly. The result is ready to use log pieces right away.

You might have noticed that we are dealing with files and blades in the process. That is why undertaking certain safety precautions is a necessity.

Precautions to take while sharpening log splitter wedge:

The two safety precautions you need to stick to include:

  1. Use safety gear:

While dealing with the wedge of blades and the files, you should always wear safety gloves and an eye mask. That way, you are less prone to suffering a cut.

  1. File both sides:

Many people are in a hurry to use the wedge.

They do not pay proper attention to both sides. Merely filing a single side of the tip is of no use. It means that the shape of the tip will be different on one side.

When that happens, there are chances that the log might be of uneven shape. Even more, the log might move swiftly to one side because of the shape of the tip. In that case, the chances of an accident increase manifold.

To avoid this, simply file the tip on both sides. That way, you will no longer have to worry about uneven cutting off logs or any injury.

If it’s a hardwood like oak or maple, then you should use a 45 degree angle. If it’s a softwood like pine or cedar, then you should use a 30 degree angle.
