I wish I had a link to a video for us. There was a TV report on self-defense for those of us that use a cane. It showed different ways to use your cane as a quick weapon and to YELL if you feel danger or someone was to grab for you, a purse or wallet. You can really wack someone in the face, stomach, arms or legs. I believe the report was for blind or nearly blind people, but I think any of us could use a cane if needed. The yelling keeps us breathing instead of holding our breath and yelling draws attention. I just thought it was worthwhile to share.
Hope we never have the need to use a cane as a weapon.
