Is Black Locust Good Wood For Carving
Is Black Locust (Robinia pseudoacacia) Good for Carving by Hand?
Black Locust (Robinia pseudoacacia) is not ideal for hand carving. Its high density and hardness (Janka hardness of 1,700 lb f) make it difficult to work with chisels and knives. But, it is valued for its durability in outdoor use. They say, “Carving Black Locust is like trying to whittle a brick!”
Black Locust is a type of hardwood found in the southeastern United States. It's a strong and heavy wood, which makes it tough to carve by hand. You'd need a lot of strength and sharp tools to work with it, kinda like trying to carve a wooden rock! But, it's great for things that need to last a long time outside.
Choosing the right wood for carving is half the battle; the other half is sharpening your tools and your patience.

Is Black Locust HARDWOOD or SOFTWOOD?
Black Locust (Robinia pseudoacacia) is classified as a hardwood. This species is known for its high density and robustness, making it more resistant to impact and pressure than typical softwoods. Despite its toughness, it boasts an impressive durability that makes it an excellent choice for outdoor applications. You could say it's as tough as an old army boot, but twice as classy!
Black Locust trees typically grow quite tall, reaching heights between 65-100 feet. They have strong and heavy trunks that can be up to 3 feet in diameter. Because of its durability, Black Locust is often used in outdoor structures, like fences and decks, where it can stand up to the weather really well.
In wood carving, understanding your wood is like understanding your tools; both take you halfway to mastery.
What are common names of Black Locust?
Black Locust (Robinia pseudoacacia) goes by several names. These include Robinia and False Acacia. It's a wood that's quite sturdy, hence, its alternative names reflect its robust nature!
Black Locust is often called by different names in various regions. People sometimes refer to it as Robinia due to its scientific name. Others might call it False Acacia because it resembles the true Acacia tree in appearance.
“A piece of wood can have many names, but its true identity is revealed through the carver's hands.”
What is the Scientific Name of Black Locust?
The scientific name of Black Locust is *Robinia pseudoacacia*. It is a hardwood species native to the southeastern United States. Known for its robustness and durability, this wood is not the easiest to carve by hand.
Black Locust, or *Robinia pseudoacacia*, stands tall and dense, making it great for outdoor uses but challenging for carvers. It's like trying to carve through a rock, but at least you won't have to worry about it breaking easily.
In wood carving, every species tells its own story through the chisel's persuasion.
What is the Tree Size of Black Locust?
Black Locust trees typically reach heights of 65-100 feet, with trunk diameters ranging from 2 to 3 feet. Their substantial size and robust trunks make them suitable for outdoor structures. You could say, “These trees are the skyscrapers of the forest—just with a little more bark and a lot less steel!”
Imagine a really, really tall tree, like as tall as a ten-story building. That's a Black Locust for you. Its trunk is thick like a large soda bottle, perfect for making stuff that needs to be super sturdy.
“A big tree brings big opportunities, but also big challenges for the carver.”
- Average Height: 65-100 feet (20-30 meters)
- Trunk Diameter: 2-3 feet (0.6-1 meter)
What is the Average Dried Weight of Black Locust?
The average dried weight of Black Locust is 48.0 lbs/ft³ (770 kg/m³). This makes it considerably dense and heavy, adding to its difficulty for hand carving. Carving Black Locust could be likened to carving a solid block of lead, but at least you get a workout!
Black Locust, with such a hefty weight, is like carrying a big rock around (except it’s wood). It’s dense and heavy, making it really strong. That's why it's so tough to work with if you’re carving by hand.
“In the world of carving, the weight of your wood can either be a burden or a blessing, depending on how sharp your tools and how strong your resolve.”

Carving Black Locust: A Tough Encounter
In forests where the locusts stand so tall,
Their sturdy trunks loom, strong and not small.
With hues of green and brown that gently fade,
But carving this tough wood? Oh, that’s a trade!
Its grains run straight, yet texturally coarse,
A challenge for chisel, knife, or any force.
Patience is key, and tools must be sharp,
For working black locust is akin to dark art.
With a hefty weight that could test your might,
Like carving through stone, it’s a strenuous fight.
Yet for outdoor needs, it earns high praise,
Withstands the storm, through sun and heavy haze.
So, while it resists decay and the rot,
about hand carving, it’s not what you sought.
Choose wisely your wood, for peace and for ease,
Sometimes it's better to whittle the breeze!
