Are you tired of spending money on getting your sawmill blades sharpened by a professional? Have you ever wondered if you can do it on your own? If so, you’re not alone. Many sawmill owners face this dilemma and question whether it’s worth it to invest their time and money in sharpening their own blades. In this blog post, we will explore this topic and provide you with the information you need to make an informed decision. So, let’s get started!

Is It Worth It to Sharpen Your Own Sawmill Blades?

Using a sawmill is an awesome way to turn raw material like logs into useful lumber, but owning and operating a sawmill is not cheap. From the cost of up-keeping the equipment to sharpening the blades, the expenses can add up quickly. This prompt begs the question: is it worth it to sharpen your own sawmill blades?


Sawmill blades are a crucial element of the sawing process, and they can be quite expensive to replace when they become dull. It makes sense to carefully consider whether sharpening your own blades is a cost-effective move for your particular sawmill setup. The following article aims to help you reach an informed decision.

Factors Affecting Sawmill Blades Lifespan

One of the most significant factors affecting the lifespan of a sawmill blade is the species of the log being cut. Harder woods like oak and maple will dull a blade faster than softer woods like cedar or spruce. Other factors can affect blade longevity, including the lubricant used, the condition of the blade when inserting, and also debarking the log before sawing.

Unnecessary Cuts and Blade Premature Dulling

Sawmill blades can prematurely dull if they are used to cut through unnecessary materials. Cutting boards into pieces that are too short or sawing through mud or bark can damage the blade, causing premature dulling.

Dull Blade Consequences

A dull blade can cause wavy boards and decrease cutting performance. It is crucial to detect when the blade becomes dull, and this can be done using a fingernail test. If the blade cuts the fingernail without creating a smooth surface, chances are the blade has become dull.

Blade Maintenance

Maintaining sawmill blades is essential for optimum cutting performance. Blades can be cleaned by wiping them down with a cloth. Also, it is essential to lubricate the blade with a vegetable-based oil that contains no chlorine or sulfur to prevent rusting. Also, Check that blade tension is correct. It is good to seek advice from a friend with experience to help with blade maintenance tips.

Blade Longevity

Sharp blades will generally last longer than dull ones. Clean blades, free of contaminants, can last all day and some more. Sharpened blades don’t stay sharp for as long as a new blade, but it is more economical to sharpen and maintain a set of blades instead of having to replace them all the time.

Cheap Blade Sharpening Tips

There are a few affordable blade sharpeners available in the market for personal use. These sharpeners can be a great investment for those who perform cutting tasks frequently. It is important to read the instructions carefully before using them on a sawmill blade.


Deciding whether to sharpen your sawmill’s blades depends on your individual circumstances. The critical factors to consider include how often you saw, the species of logs you saw, and how many blades you need sharpened.
