A novel anatomical woodworking chisel handle

Area of Science:

• Ergonomics
• Woodworking Tool Design
• Human Factors Engineering

Background:

• Traditional woodworking chisel handles may not optimize comfort or efficiency for tasks like wood scraping.
• Assessing user comfort and pain is crucial for developing effective hand tool designs.

Purpose of the Study:

• To evaluate a novel, anatomically shaped woodworking chisel handle against conventional designs.
• To compare user comfort, pain perception, and task efficiency using different chisel handles.

Main Methods:

• 18 students performed a standardized wood scraping task using an anatomical handle and seven readymade ¾-inch bench chisel handles.
• Comfort was assessed using a Comfort Questionnaire for Hand tools (CQH), and pain was mapped using a hand-based pain map.

Main Results:

• Functionality was the most important comfort concern, while sweating was the least.
• The anatomical handle received the highest ratings for comfort and was perceived as least painful across most hand regions.
• The anatomical handle also resulted in the shortest task completion time.

Conclusions:

• The novel anatomical chisel handle offers superior comfort and reduced pain compared to conventional designs for wood scraping.
• Ergonomic handle design is a significant factor in improving user experience and performance in woodworking tasks.
