I got the wild idea one day to include some foundry work in one of my advanced classes, so I took all my bullet casting equipment to school. Kids loved it. Finally, the powers that be suggested that we probably shouldn't be casting bullets. I asked if it was OK to cast fishing sinkers, since it was the same technology, I had tons of old wheel weights, and I had all the molds. Sure, that's OK, so from then on we just cast sinkers---45 caliber sinkers, 30 caliber sinkers, and 38 caliber sinkers. I just had to educate the students on what to "ask for".
I got most of my buffing compounds, wheels, etc., and blank blades from Jantz Supply. Good to know they're still in business. They were always good folks to work with.
I agree with the comment made on using your 303 as an edc--always good for a conversation starter. My coffee pards like to ask, "Well, what kinda knife you carrying today?" I try to surprise them with something different.
