The flat, thin, sharp part of a tool or weapon that cuts things.

Knife used as a weapon
A knife or other sharp weapon that a person carries, often for fighting.
รูปแบบการใช้:

Learners may confuse this with the normal, non-weapon sense of "blade" (the cutting part of a tool). In crime or street contexts, "a blade" often means the whole knife as a weapon.
คำพ้องความหมาย
knife (The general word for this object; "blade" in this sense is more informal and often suggests an illegal weapon.)
คำตรงข้าม
firearm (A weapon that fires bullets, often contrasted with knives or other blade-type weapons.)

Flat part of fan or propeller
The flat part of a machine, like a fan or propeller, that turns and pushes air, water, or something else.
รูปแบบการใช้:
the blade of [a machine/tool]

Learners sometimes think this only means something that cuts. In machines like fans or turbines, the blade’s main job is to move air or water, not to cut.
คำพ้องความหมาย
rotor blade (A more specific term for a blade on a rotating part such as a helicopter rotor or turbine.)
คำตรงข้าม
hub (The central part of a rotating machine that the blades are attached to, opposite in position to the blade.)
