Welcome, I passed through New bern on the way to go fishing many times while stationed at Fort Bragg in the 80s. As was said, throwing a hand grenade is not all that, unless you drop it while throwing. I earned an Expert badge in Grenade, so I may have a bit of perspective. As to your blacksmithing goals, they should be achievable, with the help of many of the experts on this site (of which i do not claim to be one. )
