Posted mine in the previous thread where it and the logic for carrying it seemingly were not particularly welcome. Neither have changed.
The Von Gruff design does anything any other fix blade does, but also is configured to offer a meaningful self-defense option. That too was ridiculed as unnecessary. I will simply note that self-defense situations are never events of choice.
Without any intent of any drama, I have had two experiences in Africa. Neither fortunately escalated. The first was quite a few years ago in Rundu, Namibia hard on the Angolan border. A tough town in those days - may still be. My PH went into a local market to pick up last minute provisions, while I stayed with truck with a bed full of gear including my rifle. Not an uncommon experience for clients. We were headed into the Caprivi Strip. A drunk appeared demanding money, and belaboring the existence of rich whites. He got closer and louder until I laid my hand on the hilt of my knife. I might have been able to handle him without it - after all, he had been drinking. Or I suppose I could have run away from the vehicle so he could rummage through it. In any case, he beat a hasty retreat.
The second was in Johannesburg at the City Lodge of all places. My spouse and I were overnighting on our way to Windhoek. The youth branch of the ANC was holding a convention in the hotel. Twice during the afternoon and early evening we were mildly harassed verbally by young toughs in their berets. As the night wore on, the hallways became louder and louder as drunk young people roamed them. Our door was pounded upon several times. Calls to the front desk did no good. Fortunately, the door held. But again, a sturdy blade was far more comforting and potentially intimidating than pleading had the locks failed.
As I noted in my previous post, with a very little training, a blade can be surprisingly effective where a handgun is forbidden.
