I think get those old snake in the can tricks ya know that can you open spring thing flies out
just put your blades in those and put in a box on your porch with a amazon sticker saying electronics then when someone steals it and opens
yes sarcasm of course but would be a good porch pirate deterrent
blade bank in drawer when its full transfer to a can that is under sink looks like a tiny paint can with a lid like paint cans you can pry up and put back on and will try a recycle center most likely when it fills
I got myself one of these (settling the question of my motorcycle inclination...) Meant as a money box, but perfect for the job, metal, so likely to last a while and looks the part!
I use this guy. It's been years and it's not full yet. There's a hole at the bottom that I sealed by gluing felt over it, so I can remove it and empty the blades when it finally fills up.
