Hand planes have different angles on their blades to enhance their effectiveness in different woodworking scenarios. The cutting angle, or the angle at which the blade enters the wood, plays a crucial role in determining the quality of the planed surface. By adjusting the blade angle, woodworkers can optimize the performance of their hand planes to achieve desirable results.
Factual data: Hand planes have different angles on their blades to optimize their performance based on the type of wood being planed. The cutting angle, or the angle at which the blade enters the wood, can greatly impact the quality of the planed surface. For softwoods and spalted woods that tend to bend and stretch, a low cutting angle is recommended to minimize deformation of the wood. On the other hand, dense and highly figured woods that break before they bend benefit from a high cutting angle to avoid tearout. There are two ways to achieve a low-angle cut: using a low-angle, bevel-up plane or
skewing the plane relative to the workpiece.
Bevel-up planes have a blade angle that offers reasonable edge retention and can be modified to cut at high angles.
Skewing the plane changes the functional cutting angle and allows for versatility in planing different wood surfaces. Additionally,
beveling the back of the blade or
retrofitting the plane with a different frog can increase the
effective cutting angle on bevel-down planes. It is recommended to choose a bevel-up plane for a greater range of effective cutting angles or to modify existing planes based on the specific wood being planed.
Key Takeaways:
- Hand planes have different blade angles to optimize their performance in woodworking.

Understanding the impact of blade angles in hand planes
The cutting angle of a hand plane blade plays a significant role in determining the results of planing and can greatly impact the quality of the finished surface.
Different blade angles in hand planes offer various benefits and are suited for specific woodworking techniques. Understanding the effects of blade angles is essential for optimizing hand plane performance.
When it comes to softer woods and spalted woods that tend to bend and stretch, a low cutting angle is recommended. A low-angle cut minimizes deformation of the wood, resulting in smoother surfaces. On the other hand, dense and highly figured woods that have a tendency to break before they bend benefit from a high cutting angle. This prevents tearout and produces cleaner cuts.
To achieve a low-angle cut, there are two main approaches. The first is using a low-angle, bevel-up plane. These planes have a blade angle that can be modified to cut at high angles when necessary. The second approach is skewing the plane relative to the workpiece. Skewing changes the functional cutting angle and allows for versatility in planing different wood surfaces.
Modifying existing hand planes can also be done to accommodate different blade angles. By
beveling the back of the blade or
retrofitting the plane with a different frog, the
effective cutting angle on bevel-down planes can be increased. This flexibility allows woodworkers to choose the right blade angle based on the specific wood being planed.
Impact of blade angles on planing results
The table below summarizes the effects of different blade angles on planing results:
| Blade Angle |
Planing Results |

– Minimizes tearout on dense and figured woods.
– Suitable for softwoods and spalted woods that tend to bend.
– Produces smoother surfaces. |
| Medium Angle (30-45 degrees) |
– Balances tearout and cutting efficiency.
– Suitable for most woodworking applications. |
| High Angle (Greater than 45 degrees) |
– Reduces tearout on highly figured woods.
– Recommended for dense woods that break before they bend.
– Provides cleaner cuts. |
By understanding the impact of
blade angles in hand planes, woodworkers can select the appropriate blade angle for different woodworking tasks. Whether it’s using a low-angle plane, skewing the plane, or modifying existing hand planes, optimizing the cutting angle can result in better planing performance and improved surface quality.
Hand planes can be equipped with different blade bevel angles, each offering unique advantages depending on the type of wood being planed. The bevel angle, also known as the cutting angle, refers to the angle at which the blade enters the wood. This angle plays a crucial role in achieving optimal planing results.
When it comes to softwoods and spalted woods that are prone to bending and stretching, a low cutting angle is recommended. This helps minimize the deformation of the wood and ensures a smoother planed surface. On the other hand, dense and highly figured woods that are more likely to break than bend benefit from a high cutting angle. A high cutting angle helps prevent tearout and ensures cleaner cuts.
There are two main ways to achieve a low-angle cut: using a low-angle, bevel-up plane or skewing the plane relative to the workpiece.
Bevel-up planes have a blade angle that provides reasonable edge retention and can be easily modified to cut at higher angles. Skewing the plane, on the other hand, changes the effective cutting angle and offers versatility in planing different wood surfaces.
Additionally, it is possible to modify existing hand planes to accommodate different blade angles.
Beveling the back of the blade or
retrofitting the plane with a different frog can increase the effective cutting angle on bevel-down planes. This allows woodworkers to choose the most suitable blade angle for the specific wood being planed, ensuring optimal performance and results.

Achieving Low-Angle Cuts in Hand Planes
To achieve low-angle cuts, hand planes can utilize bevel-up planes or skewing techniques to modify the cutting angle. The choice of method depends on the specific wood being planed and the desired outcome.
Bevel-up planes are a popular choice for achieving low-angle cuts due to their design. These planes have a blade mounted with the bevel facing upwards, allowing for a lower cutting angle. The low cutting angle minimizes the risk of tearout and improves the surface quality when planing softwoods or woods prone to bending and stretching. Bevel-up planes offer reasonable edge retention and can be further modified to cut at high angles depending on the woodworking requirements.
Skewing the plane is another technique frequently employed to achieve low-angle cuts. By tilting the plane slightly relative to the workpiece, the effective cutting angle changes. This technique allows for versatility in planing different wood surfaces and can help reduce tearout. Skewing the plane can be particularly useful when planing highly figured or dense woods that are prone to tearout due to their structure.
For those who prefer using bevel-down planes, it is still possible to achieve low-angle cuts by modifying the plane. Beveling the back of the blade, also known as a back bevel, increases the effective cutting angle. This modification can be done by carefully sharpening the back of the blade to create a secondary bevel. Additionally, retrofitting the plane with a different frog, which holds the blade in place, can allow for a higher effective cutting angle on bevel-down planes.
Summary:
- To achieve low-angle cuts, hand planes can utilize bevel-up planes or skewing techniques to modify the cutting angle.
- Bevel-up planes are designed with the blade mounted facing upwards, offering a low cutting angle and minimizing tearout on softwoods and bendable woods.
- Skewing the plane by tilting it relative to the workpiece changes the effective cutting angle and provides versatility in planing different wood surfaces.
- Beveling the back of the blade or retrofitting the plane with a different frog can increase the effective cutting angle on bevel-down planes.

Is the adjustable frog on a hand plane related to the angle of the blade?
The angle of the blade on hand planes with adjustable frogs can indeed be affected by the positioning of the frog. By adjusting the frog forward or backward, the angle between the blade and the sole of the plane can be altered, influencing the cutting performance and the type of wood shaving produced.
Modifying existing hand planes for different blade angles
Hand plane users can modify their existing tools by beveling the back of the blade or retrofitting the plane to achieve different cutting angles based on the wood being planed. Beveling the back of the blade involves creating a secondary bevel on the flat side of the blade, effectively reducing the cutting angle. This technique is particularly useful when planing softwoods or spalted woods that are prone to deformation. By decreasing the cutting angle, the blade encounters less resistance, resulting in smoother planed surfaces.
Another method of modifying hand planes is by retrofitting the plane with a different frog. The frog is the adjustable part of the plane that holds the blade in place. By swapping out the frog, users can change the pitch and cutting angle of the blade. This allows for greater versatility in planing different wood surfaces, as the ideal cutting angle varies depending on the wood’s density and figure.
When
choosing the right blade angle for hand planes, it’s essential to consider the type of wood being planed. Softwoods and spalted woods benefit from a lower cutting angle to minimize deformation, while dense and highly figured woods require a higher cutting angle to prevent tearout. By modifying existing hand planes, woodworkers can optimize their tools to achieve the best results for specific woodworking projects.
