hopefully this is a joke, giving a 10 year old a sword is extremely dangerous. there are plenty of mass shooters, a sword isn’t going to protect him in the modern age. you need to buy this little guy a gun. a lot of people would say to start him off with something small, but i say get him used to something heavier with more kick first so he REALLY learns how to use it. it also ups the risk to himself and will make him more cautious, whereas with a smaller gun he might be tempted to twirl it (which is cool, but you can teach him how to do that later)
