Yes, some monkeys can use a knife and fork, though their use is limited and not as precise as humans'—studies show they often adopt unconventional grips like the reverse (ice pick) grip for stabbing rather than slicing.
Can monkeys use utensils?
Monkeys can use utensils like knives and forks to some extent, primarily for food manipulation or simple tasks such as stabbing or scooping, though their precision and technique differ from humans.
According to National Geographic, tool use in primates is instinctive for survival tasks like cracking nuts or digging for insects. While they may not "use" utensils in the human sense, their ability to hold and apply force demonstrates cognitive adaptability. Take capuchin monkeys in Brazil, for instance—they’ve been observed using stone tools to crack nuts, showing early tool-use behaviors similar to primitive knife manipulation.
What kind of knife did Crocodile Dundee use?
The knife used in the Crocodile Dundee films is a Bowie-style hunting knife, custom-made by Australian gunsmith John Bowring.
This iconic blade, nicknamed the "Dundee Bowie," features a large, fixed blade with a clip point and a distinctive handle. It was crafted specifically for the 1986 film and instantly became a cultural symbol of Australian bushcraft. You’ll still find replicas today from specialty knife makers, though the original is a collector’s item. The design prioritizes raw strength and durability—perfect for the wilderness survival scenarios in the movie.
Who says “that’s not a knife”? “This is a knife”?
Paul Hogan’s character, Mick Dundee, delivers the line “That’s not a knife. This is a knife” in the 1986 film Crocodile Dundee.
This quote became one of Australia’s most quoted movie lines. Later, in 2021, it popped up in a Grill’d marketing campaign—a burger chain that got tangled in legal disputes over trademark use. While Grill’d’s founder argued the phrase had entered public domain, Hogan and the original studio fought to protect their rights. Honestly, this is the best kind of legal battle—one rooted in pop culture.
What movie is “that’s not a knife” from?
The phrase “That’s not a knife. This is a knife.” comes from the 1986 film Crocodile Dundee, starring Paul Hogan.
This moment happens in a tense scene where Mick Dundee dramatically pulls out an enormous survival knife to defend himself. The sheer size of the blade and his bushcraft skills made it unforgettable. Since then, the line has been parodied and referenced everywhere—TV shows, films, ads—you name it. It’s now cemented in pop culture history.
Is a knife a wedge?
Yes, a knife functions primarily as a wedge, which is a simple machine designed to split or separate objects by concentrating force on a narrow edge.
A knife blade is essentially two inclined planes meeting at a sharp edge. When you apply force to the handle, the wedge shape pushes material apart, reducing the effort needed to cut. That’s why even a dull knife feels harder to use—the wedge angle and edge geometry directly impact cutting efficiency.
Is a fork a wedge?
A fork isn’t traditionally a wedge, but its tines act like tiny wedges when piercing or separating food.
While forks don’t split material like a knife blade, their pointed tines concentrate force when stabbing or lifting. Some prongs are slightly tapered, which could be seen as a micro-scale wedge effect. Still, forks are better classified as levers or piercing tools rather than true wedges.
How does a knife work as a wedge?
A knife works as a wedge because its tapered blade converts downward force into lateral splitting force, allowing it to cut through materials by pushing them apart along its sharp edges.
When you press a knife into an apple, for example, the blade’s wedge shape applies pressure to a minimal surface area. This increases pressure (force per unit area), letting the knife penetrate with less effort than pushing with a flat object. The sharper the knife, the thinner the wedge angle—and the easier it cuts. That’s why regular sharpening makes such a difference.
What are the 3 types of inclined planes?
The three types of inclined planes are fixed, movable, and spiral, each serving a distinct purpose in mechanical advantage.
Fixed inclined planes include ramps and slides, which let objects be raised gradually with less force. Movable inclined planes are tools like wedges and axes, where the plane itself moves to cut or split. Spiral inclined planes appear in screws and drill bits, converting rotating force into linear motion. These variations are everywhere—in engineering, construction, and everyday tools.
What is a real life example of an inclined plane?
A real-life example of an inclined plane is a wheelchair ramp, which lets users move upward with reduced effort compared to climbing stairs.
Other common examples? Escalators, loading ramps for trucks, and roads with gentle grades. These designs reduce the force needed to move objects or people vertically by increasing the distance over which the force is applied. Inclined planes are one of the six classical simple machines because they multiply force so efficiently.
Do stairs count as an inclined plane?
Yes, stairs function as a modified inclined plane, converting a steep vertical climb into a series of smaller, manageable steps.
Each step acts like a tiny horizontal platform, reducing the overall angle of ascent. This makes climbing easier for humans and animals alike. The total rise (vertical height) is spread over a longer run (horizontal distance), lowering the force required per step. That’s why stairs are more accessible than ladders for most people.
Is a knife an inclined plane?
A knife isn’t classified as an inclined plane, but its blade is made up of two inclined planes meeting at an edge, giving it wedge-like cutting properties.
An inclined plane is a flat surface set at an angle, like a ramp. A wedge, however, is a double-sided inclined plane designed to split or cut. The blade of a knife functions primarily as a wedge, not a single inclined plane. Still, the beveled edges of the blade can be seen as micro-inclined planes that guide material apart as the knife cuts.
What 2 simple machines make up a shovel?
A shovel combines a wedge and a lever, with the blade acting as the wedge and the handle functioning as a lever.
When you push a shovel into soil, the blade’s wedge shape splits and lifts the earth. The long handle acts as a lever, letting you apply force at one end to lift a greater load at the other. This dual mechanism makes digging far more efficient. Some shovels even incorporate a fulcrum—like when you step on the blade—enhancing their lever function even further.
Who says “that’s not a knife, this is a knife”?
Paul Hogan’s character, Mick Dundee, says the line in the 1986 film Crocodile Dundee.
Hogan later argued that Grill’d, an Australian burger chain, blatantly used the catchphrase in a 2021 marketing campaign without a license. Grill’d’s founder, Simon Crowe, countered that the line had become so widely used it was effectively public domain. The legal dispute highlighted how deeply the quote had embedded itself in Australian culture.
What movie is “that’s not a knife” from?
The phrase originates from the 1986 film Crocodile Dundee, starring Paul Hogan.
In the scene, Mick Dundee dramatically pulls out an enormous survival knife during a tense confrontation. The line has since been parodied and referenced in countless TV shows, films, and advertisements worldwide, cementing its place in pop culture history.

Wheelchair ramps, escalators, and loading ramps are all real-life examples of inclined planes.
These designs reduce the force needed to move objects or people vertically by increasing the distance over which the force is applied. Other examples include sloping roads, carpenter’s planes, and even hatchets. Inclined planes are one of the six classical simple machines because they multiply force so efficiently.
