well pepperspray, teargas, taxers, etc are illegal in my country. The legal selfdefence "weapons" you are allowed to use are sprays ( the only spray that actually block vision uses foam for that purpose... ), personal alarms ( CO or battery powered ) and the flashlight.

Also i think the actual chance of getting attacked is too low for me to carry a specific selfdefence "weapon", that is proberbly not very effective anyways. A high power multipurpose flashlight is already part of my EDC, so it's more suited in my situation. It also draws less attention than the alternative´s.
