Ice pick

Ice pick is a physics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Ice pick rather than just read about it. In short: An ice pick is a pointed metal tool used to break, pick or chip at ice. The design consists of a sharp metal spike attached to a handle.

Key takeaways

  • Ice pick belongs to physics; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Ice pick to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Ice pick from memory before moving on to harder problems.

Reference excerpt

An ice pick is a pointed metal tool used to break, pick or chip at ice. The design consists of a sharp metal spike attached to a handle. Though traditionally made out of wood, modern variants may have a plastic or rubber handle to improve safety and grip. Otherwise, the tool's design has been relatively unchanged since its invention.

History During the 1800s, ice blocks were gathered from frozen water sources and distributed to nearby homes. Ice picks were used to easily cut the blocks into smaller pieces for use. In many cases these smaller blocks were used in iceboxes. Iceboxes are similar in use to refrigerators, with the major difference being that iceboxes could only stay cold for a limited time. They needed to be restocked with ice regularly to continue proper functioning. The ice pick slowly began to lose popularity beginning in the early to mid-1900s due to the creation of the modern refrigerator. Many refrigerators came with a built-in ice maker which allowed for easy access to small ice chunks at any time and eliminated the need for the ice pick.

Modern usage Some bartenders will carve or chip blocks of ice into aesthetically pleasing shapes to be served with their drinks, using tools including an ice pick. Because blocks of ice melt much more slowly than cubes, sailors, campers and others who will be away from civilization for periods of time may carry blocks of ice along with an ice pick to shape and serve the blocks.

Use as weapon Because of its availability and ability to puncture the skin easily, the ice pick has sometimes been used as a weapon. Most notoriously, New York's organized crime groups known as Murder Incorporated made extensive use of the ice pick as a weapon during the 1930s and 1940s. There were up to 1,000 murders committed by this group. In 1932, the bodies of two young men were found who had been stabbed numerous times with an ice pick. A man named Jacob Drucker was found guilty of murdering a man in 1944. His victim had been stabbed with an ice pick over 20 times. The most feared hitman of his day, Abe Reles, used the ice pick as his weapon of choice, usually stabbing his victims in the ear. According to New York City police, ice picks are still used today as street weapons. On August 21, 2012, a man was attacked with an ice pick in the Bronx. John Martinez, a man from the Bronx, was convicted of several robberies using an ice pick in 2011. Murderer Richard Kuklinski, who claimed to have killed over 200 people, was reported to have used an ice pick among other weapons. During the early morning of August 16, 1975, Utah Highway Patrol Trooper Robert Hayward arrested Serial Killer Ted Bundy, amongst the items found during a search of Ted's Volkswagen was a brown gym bag containing a red handled ice pick along with handcuffs, rope, ski mask, panty hose mask, flashlight, GLAD garbage bags, and other incriminating items. Leon Trotsky is sometimes incorrectly said to have been killed with an ice pick. He was actually killed with an ice axe, a mountaineering tool. An item that resembled an ice pick (later revealed as a screwdriver) and a kitchen knife were used by Luka Magnotta to murder Jun Lin in 2012.

Use in medicine The lobotomy was a medical treatment that gained popularity during the mid-1930s. Lobotomist Walter Freeman performed thousands of lobotomies across the world. Though he would later use a specially commissioned tool called an orbitoclast, he reportedly originally experimented using an ice pick from his family's kitchen. The pick would be inserted into the brain through the eye socket. The procedure would be done without the use of anesthetics. This "Ice Pick Lobotomy" was believed to diminish mental issues, however, these often resulted in paralysis and early death. This treatment failed due to a lack of testing before being performed on thousands of people. Walter Freeman's medical license was revoked in 1967 after a woman died during a lobotomy. This method of lobotomy led to the deaths of around 500 people over the course of 50 years. By the 1970s, the procedure would be banned in many countries for being "inhumane".

In popular culture In the 1992 film Basic Instinct, the character Catherine Tramell (played by Sharon Stone) is strongly associated with an ice pick, used in the film’s infamous opening murder scene.

Worked examples

Example 1 — a first encounter with Ice pick

Start with the simplest possible case. Write down what Ice pick claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Ice pick before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Ice pick ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Ice pick

In research
Ice pick appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Ice pick in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Ice pick is common in secondary-school and first-year university syllabi. It links to neighbouring topics Mechanical hand tools, so understanding it makes those chapters shorter.
In everyday life
Look for Ice pick outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Ice pick in simple terms?

An ice pick is a pointed metal tool used to break, pick or chip at ice. The design consists of a sharp metal spike attached to a handle.

Why does Ice pick matter?

Because it connects several physics ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Ice pick?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
