How to Sharpen Chisels with Sandpaper


Updated on:

Sharpening chisels is an important skill to have for any woodworker. A sharp chisel is necessary for precise cuts and a clean finish on your workpiece. While there are many methods to sharpen chisels, using sandpaper is a simple and cost-effective option that can yield great results. To sharpen your chisels with sandpaper, you will need a few materials including sandpaper, a flat and smooth surface to mount the sandpaper on, and a honing guide. The process involves first sharpening the back of the blade, then honing the primary bevel, and finally honing the micro bevel. With some practice, you can achieve a razor-sharp edge on your chisels using this method. In this article, I will provide a step-by-step guide on how to sharpen chisels with sandpaper. Whether you are a beginner or an experienced woodworker, this method can be a valuable addition to your skillset. So, let’s get started and learn how to sharpen chisels with sandpaper.

Understanding Chisels and Sandpaper As someone who has spent a lot of time working with chisels, I’ve found that using sandpaper is a cost-effective and accessible way to sharpen them. In this section, I’ll go over the basics of chisels and sandpaper, so you can understand how to use them together to achieve a sharp edge.

Types of Chisels

There are many types of chisels, each designed for a specific task. Here are a few of the most common types of chisels you may encounter:

Type of Chisel Description
Bench Chisel Used for general woodworking tasks
Mortise Chisel Used for creating mortise joints
Paring Chisel Used for fine, delicate work
Firmer Chisel Used for heavy-duty work

When selecting a chisel, it’s important to consider the type of work you’ll be doing and choose a chisel that’s appropriate for the task.

Grades of Sandpaper

Sandpaper is available in a range of grades, from coarse to fine. The grade of sandpaper you choose will depend on the condition of your chisel and the level of sharpness you’re trying to achieve. Here are a few of the most common grades of sandpaper:

Grade of Sandpaper Description
Coarse Used for removing nicks and chips from the chisel
Medium Used for sharpening the chisel
Fine Used for honing the chisel to a razor-sharp edge

When using sandpaper to sharpen a chisel, it’s important to start with a coarse grade and work your way up to a fine grade. This will ensure that you remove any imperfections in the blade and achieve a sharp edge.

Preparation Steps Before sharpening your chisels with sandpaper, it’s important to gather the necessary materials and take some safety precautions. Here are the steps you should follow:

Gathering Materials

To sharpen your chisels with sandpaper, you will need the following materials:

  • Chisels: Make sure you have the chisels that you want to sharpen.
  • Sandpaper: You will need different grits of sandpaper, starting with a coarse grit (around 120), moving up to a medium grit (around 400), and ending with a fine grit (around 1000).
  • A flat surface: You will need to place your sandpaper on a flat surface, such as a piece of glass or granite, to ensure you’re sharpening your chisels evenly.
  • Honing guide (optional): A honing guide can help you maintain the correct angle while sharpening your chisels.

Safety Precautions

Sharpening chisels with sandpaper can be a safe process if you take the necessary precautions. Here are some safety tips to keep in mind:

  • Wear eye protection: When sharpening your chisels, small particles of metal and sandpaper can fly off and potentially injure your eyes. Wear safety goggles to protect your eyes.
  • Use a vise: Secure your chisel in a vise to prevent it from slipping while you’re sharpening it.
  • Keep your fingers away from the blade: When sharpening your chisel, make sure your fingers are away from the blade. You can use a piece of wood or a honing guide to hold the chisel while you’re sharpening it.
  • Be aware of the blade’s direction: Always sharpen your chisel in the same direction as the bevel. If you sharpen it in the opposite direction, you can damage the blade.

Sharpening Process When it comes to sharpening chisels with sandpaper, there are two main steps to the process: initial sharpening and honing the edge.

Initial Sharpening

The first step in sharpening a chisel with sandpaper is to establish a primary bevel angle. This is done by grinding the edge of the chisel against a coarse grit sandpaper until a burr forms. To do this, wrap the sandpaper around a flat surface, such as a block of wood, and hold the chisel at a consistent angle while moving it back and forth against the sandpaper. Once a burr forms, flip the chisel over and repeat the process on the other side. It’s important to maintain a consistent angle throughout the sharpening process to ensure a sharp and even edge. A honing guide can be used to help maintain this angle.

Honing the Edge

After establishing the primary bevel angle, the next step is to hone the edge of the chisel to a razor-sharp finish. This is done by using progressively finer grits of sandpaper to remove the burr and polish the edge. Start by using a medium grit sandpaper to remove the burr and refine the primary bevel. Then, move on to a fine grit sandpaper to polish the edge and remove any scratches left by the coarser grits. Finally, use a very fine grit sandpaper to achieve a mirror-like finish on the edge. When honing the edge, it’s important to use a consistent angle and apply even pressure to the chisel. A honing guide can be used to help maintain the angle, and a strop can be used to remove any remaining burr and polish the edge even further. By following these steps, you can achieve a razor-sharp edge on your chisels using sandpaper. With a little practice and patience, you’ll be able to sharpen your chisels quickly and easily, ensuring clean and precise cuts every time.

Maintenance and Aftercare

After sharpening your chisels with sandpaper, it is important to maintain them properly to ensure that they stay sharp and in good condition. Here are a few tips on how to care for your chisels:

  • Clean your chisels after each use to prevent rust and other damage. Use a soft cloth to wipe them down and remove any debris or dust.
  • Store your chisels in a dry place, away from moisture and humidity. A tool roll or box is a great option for storing chisels safely.
  • Oil your chisels regularly to prevent rust and keep them lubricated. Apply a thin layer of oil to each chisel and wipe away any excess.
  • Check your chisels regularly for any signs of damage or wear. If a chisel is bent or has a chip, it will need to be repaired or replaced.
  • Sharpen your chisels regularly to maintain their sharpness. Depending on how often you use your chisels, you may need to sharpen them every few weeks or months.

By following these simple maintenance tips, you can keep your chisels in great condition and ensure that they are always ready to use when you need them.
