What is a Blade?
A blade is a flat, elongated, and typically narrow piece of metal, plastic, or other material, that is designed for cutting, scraping, or thrusting. It is a common tool used in various activities such as cooking, gardening, and construction.
Types of Blades
There are several types of blades, each designed for specific purposes:
- Utility Knife Blade: Used for cutting and scoring various materials such as cardboard, leather, and linoleum.
- Serrated Blade: Characterized by its jagged edge, used for cutting through tough or fibrous materials such as bread and meat.
- Circular Saw Blade: Designed for use with circular saws to cut through wood, metal, or plastic.
- Scalpel Blade: Extremely sharp and used in medical and surgical procedures for precise cutting.
- Mower Blade: Used in lawnmowers to cut grass to an even length.
Blade Safety
When using any type of blade, it is important to observe safety precautions to prevent accidents and injuries:
- Always use the appropriate blade for the specific task.
- Keep blades sharp to prevent slipping and use less force when cutting.
- Store blades in a safe place and keep them out of reach of children.
- Use protective gear such as gloves and goggles when handling blades.
- Dispose of used blades properly in a designated container.
Fun Facts About Blades
Here are some interesting facts about blades:
- The oldest blades found are over 2.5 million years old and were made from volcanic glass.
- The world's largest pocket knife was built in 2005 and stands at 7.62 meters tall.
- Scalpel blades are so sharp that they can cut through skin with minimal pressure.

PHYSICAL SCIENCE
Motion and Stability: Forces and Interactions
Investigate the resulting motion of objects when forces of different strengths and directions act upon them (e.g., object being pushed, object being pulled, two objects colliding).
Use observations and data from investigations to determine if a design solution (e.g., designing a ramp to increase the speed of an object in order to move a stationary object) solves the problem of using force to change the speed or direction of an object.
LIFE SCIENCE
Ecosystems: Interactions, Energy, and Dynamics
Distinguish between living and nonliving things and verify what living things need to survive (e.g., animals needing food, water, and air; plants needing nutrients, water, sunlight, and air).
