Frequently Asked Questions
What is butternut wood and what is it known for?
Butternut, also known as white walnut, is a domestic hardwood with a warm, light brown colour similar to walnut but significantly softer. It has a coarse, open grain with an attractive appearance and a Janka hardness of approximately 490. Butternut is known for its ease of carving and working with hand tools, and has been used in North American furniture and woodworking traditions for generations.
How does butternut compare to black walnut?
Butternut and black walnut are closely related species in the same genus. Butternut is significantly softer and lighter in colour, with a pale tan-brown tone compared to walnut's rich chocolate brown. Walnut is harder, denser, and more durable for furniture applications. Butternut carves more easily and is a better choice for detailed hand carving. Both species have attractive, complementary grain characters.
What is butternut used for in woodworking?
Butternut is used for furniture, carved decorative items, interior panelling, millwork, and musical instrument components. It is a traditional carving wood in North America. Its soft, workable nature and attractive colour make it suitable for decorative woodworking where detailed carving is part of the design. It is not suitable for high-wear surfaces or exterior applications.
Is butternut endangered or difficult to source?
Butternut has been significantly affected by butternut canker, a fungal disease that has killed a large proportion of butternut trees across eastern North America. As a result, butternut lumber can be less consistently available than common domestic hardwoods. Windsor Plywood sources butternut through responsible suppliers when available. Contact your local branch to confirm current availability before specifying butternut for a project.
What finish is best for butternut?
Oil finishes and penetrating wiping varnishes are traditional choices for butternut that enhance its warm colour and open grain without obscuring the wood's natural character. Butternut also accepts paint and stain. A grain filler is recommended for a smooth painted finish due to the open grain structure. Clear finishes with UV inhibitors help preserve the warm tone from darkening with light exposure.
