Some woods are valued for strength and others for color. Buckeye burl is valued for pattern. A single piece can show gray, white, black, beige and warm brown swirls, and no two pieces look alike. This guide explains what buckeye burl is, where it comes from, how it behaves in the shop and what people make with it.
What is a burl?
A burl is an abnormal growth on a tree in which the grain grows in a tight, twisted, chaotic pattern instead of running in straight lines. Burls are generally thought to form in response to stress, injury or infection. That distorted grain creates the swirls, knots and “eyes” that woodworkers prize.
What is buckeye?
Buckeyes are trees in the genus Aesculus. The burl most widely sold today comes from the California buckeye (Aesculus californica), which is native to California and Oregon. Ohio buckeye (Aesculus glabra) and yellow buckeye (Aesculus flava) also produce burl, mainly in the eastern United States.
Why is the color so unusual?
Sellers and woodturners attribute the gray, black and orange tones in buckeye burl to oxidation from minerals the burl absorbs. As a result, color varies widely between pieces and even within a single blank.
Buckeye burl properties
- Hardness: Soft. Published Janka figures range from roughly 350 to 770 lbf depending on the species and source. Burl is irregular, so treat any single number as approximate.
- Weight: Light to medium. Ohio buckeye is listed at about 520 kg/m³.
- Workability: Easy to cut, but the low density can cause fuzzy surfaces and torn grain.
- Durability: Low natural rot resistance, so it is not suited to outdoor use.
- Finishing: Takes glue and finish well.
Why is buckeye burl usually stabilized?
Raw buckeye burl is soft and can crumble, chip or contain voids. Stabilization infuses the wood with resin under pressure, which hardens it, reduces movement and lets it take a high polish. Stabilized blanks can also be dyed. Most buckeye burl pen blanks sold today are stabilized.
Common uses of buckeye burl
- Pen and pencil blanks
- Electric guitar and bass tops and backs
- Knife scales and grips
- Hollow forms, bowls and boxes
- Veneer, inlay and other decorative work

Photos only go so far with a wood this varied. In the video below, we cut into the burl so you can see how the grain and color open up.
How to choose a piece of buckeye burl
- Color: Mostly gray, mixed, or light with dark figure.
- Size: Pen blanks, thin tops, turning blocks or slabs.
- Stabilized or natural: Stabilized is easier to finish and more forgiving for beginners.
- Voids and cracks: Check photos for gaps that may need filling.
Tips for working with buckeye burl
- Use sharp tools and light cuts to limit tear-out.
- Sand through the grits and fill small voids before the final finish.
- Use a hard finish such as CA glue or lacquer to bring out depth.
- Wear dust protection, as with any wood.
