[hank ernade]

1 piece 1x2” wood the length of your forearm.
Wrap it to your forearm with an Ace bandage.
Put on your jacket.
Use it to block blows from sticks or clubs.
If someone gets in your face bop them with it.

Don’t carry a weapon.

[miserare]

That sounds very cumbersome.

There are lighter weapons that work much better for self defense. (hint-hint.)
