Aha!
There it is!

From the FL Statutes.
It says…..

776.012 Use of force in defense of person.
–A person is justified in using force, except deadly force, against another
when and to the extent that the person reasonably believes that such conduct
is necessary to defend himself or herself or another against the other’s imminent
use of unlawful force. However, a person is justified in the use of deadly force
and does not have a duty to retreat if:

(1) He or she reasonably believes that such force is necessary to prevent
imminent death or great bodily harm to himself or herself or another or to prevent
the imminent commission of a forcible felony; or

(2) Under those circumstances permitted pursuant to s. 776.013.

…and then,

776.08 Forcible felony.
–“Forcible felony” means treason; murder; manslaughter; sexual battery; carjacking;
home-invasion robbery; robbery; burglary; arson; kidnapping; aggravated assault;
aggravated battery; aggravated stalking; aircraft piracy; unlawful throwing,
placing, or discharging of a destructive device or bomb; and any other felony
which involves the use or threat of physical force or violence against any individual.

…and lastly,

790.10 Improper exhibition of dangerous weapons or firearms.
–If any person having or carrying any dirk, sword, sword cane, firearm,
electric weapon or device, or other weapon shall, in the presence of one or more persons,
exhibit the same in a rude, careless, angry, or threatening manner, not in necessary self-defense, the person so offending shall be guilty of a misdemeanor of the first degree,
punishable as provided in s. 775.082 or s. 775.083.

Now.
The way I understand it,

You can only do 776.012,
if you are under 776.08
but you can not 790.10.

I see.
Now only 2 questions left in mind.

1. Should I feel safer now?

and 2,
What in the hell is a “Dirk?”
And who uses it?

(Okay that was 3.)

–update: Here’s a picture of a ” Dirk.“
