5 words a day - day 34

1) blast (noun)
A sudden blast made him fall over so unluckily he twisted his hand.
A blast is bigger, more like an explosion. If there was a sudden blast a person would likely be severely inured. Your sentence is correct, but I might say it like this instead, "A sudden blast made him fall over and caused him to twist his hand." 

2) gobble (verb)
A hawk catches mice and gobbles them in one piece.
"A hawk catches a mouse and gobbles it up in one piece" Usually for the verb gobble, meaning to eat quickly, we say "gobble up." It is more used for slang than formal speaking. 

3) sleight (noun)
Thanks to a bold sleight he had managed to free himself right before beheading, but he hadn't been running away quickly enough and they caught him again. This is correct. In English, we don't use this word much at all, except for speaking about magic trick or card playing. Then we use the expression "Sleight of hand."

4) pendant (noun)
When I was a little boy, I played basketball with my unckle uncle once in the living room at my grandmother's house. At some moment (at some point), I threw the ball so powerfully my uncle hadn't managed to catch it and it bounced off the wall smashing the pendant. No need (needless) to say my grandma wasn't pleased. Though it is correct, this sentence still doesn't define what a pendant is. Most commonly, it refers to a type of jewlery.

5) colon (noun)

It is advised to put a colon in a sentence before you start enumerating things.  (this is a colon :  )
A colon is also a body part-- part of the large intestines/rectum/digestive tract.
