When dealing with woodworking, choosing the right tool and understanding its proper usage can make all the difference. One key component of any woodworker's arsenal is the chisel. However, a common question many encounter is, "What do you hit a wood chisel with?" Some believe in using a mallet, others stick to the traditional hammer. This article clarifies the proper usage of wood chisels, highlighting the three main types along with the implications of using different tools.

The Three Main Types of Wood Chisels

Woodworking chisels come in three primary types, each with distinct characteristics and uses. Understanding the right tool for the job is crucial for precision and durability.

Firmer Chisels

Usage: Ideal for paring tasks. Handle: Not reinforced, designed for hand manipulation. Advantages: Ideal for delicate work where control is essential.

Bevel or Combination Chisels

Purpose: Popular for creating mortices. Handle: Reinforced for light to moderate hammering with a mallet. Blade: Strong enough for shallow mortices, yet thin enough for hand paring.

Mortice Chisels

Design: Strong, oversized handles made for mallet pounding. Blade: Tapered and robust, suitable for deep mortice work. Usage: Ideal for prying chippings from the bottom of deep mortice cuts.

Choosing the Right Tool for Each Chisel

For precision chisels, such as the firmer and paring chisels, it's essential to use your hands for optimal control and accuracy. For the bevel or combination chisel, a mallet made of wood or rubber is recommended for light to moderate hammering, or a suitable hammer if careful force control is maintained.

The mortice chisel is the exception, as it is designed for use with a mallet. Its strong, oversized handle is specifically made to withstand the force required for deep mortice cuts.

Why Avoid Using a Hammer?

In woodworking, using a hammer on a chisel can potentially damage the chisel or render it unfit for its intended purpose. Here’s why:

Handle Integrity: Hammering can splinter the handle, reducing grip and control. Blade Dulling: The force from a hammer can cause the chisel blade to dull or even break, leading to poor performance and increased risk of accidents. Damage to Workpiece: Using a hammer can also damage the wood, leading to poor finishing and increased work after the initial cut.

For precision chisels like the paring chisel, it’s particularly important to avoid using a hammer as it can easily destroy the blade or the precise edges necessary for fine work.

When to Use a Mallet

A mallet is your best bet for chisels that need additional force. Here’s when and how to use one:

Selection: Choose a mallet made of wood or rubber to avoid damaging the chisel handle. Metal mallets are not recommended as they can damage the chisel handle. Force Control: For the bevel or combination chisel, use light to moderate force. For the mortice chisel, use the full force of the mallet. Consistency: Maintain a consistent strike to avoid uneven chipping and ensure accurate cuts.

Conclusion

Choosing the right tool for your wood chisel is crucial for achieving the best results in your woodworking projects. Remember, precision chisels should be used by hand, while mallets are ideal for providing additional force when necessary. By understanding the appropriate tools for each chisel, you can enhance your woodworking skills and create beautiful, high-quality work.
