Till the spring mechanism breaks . better a small fixed blade boot knife or push dagger with a 2-3 inch blade combined with training at your local martial arts school in basic self defense will allow you to quickly & more importantly quietly stop a attacker.
I have a crapload of fixed daggers, boot length and otherwise.
The switches are mostly for “fun”.
One might well break in the future but the Beltrame has a warranty, so it’s all good.
I would *love* some training but I have severe issues with balance, thanks to a near fatal head injury.
Not sure how I could ever manage to ‘spin’ without falling over.
