I don’t know about where you live, but it really isn’t rare at all. Some areas more so than others I’m sure, but it is far from a rare occurrence. Pocket knives are even more common, do you have a problem with knives as well? My kids all got their first knife by the age of 6, some were younger. My husband grew up in Mexico. His favorite toy was his dad’s machete, until he was 3. Then his favorite toy was his own machete. He got it as a Confirmation gift, a machete and a belt. He was so proud!!! It’s the culture in my husbands town. They use them as tools, and they use them for fun. If a kid gets hurt or, even worse, killed, most people would wonder how something so terrible could happen. It would be viewed as a tragic accident. No one would even think of punishing the parents more than they already are punished. It is so rare a kid is hurt that no one can imagine it happening. Do you think that is wrong of them too?
