"Don't use a nice knife on anything other than food. (a common offense would be opening a food package with it)
Don't send a nice knife through a dishwasher
Don't leave a sharp knife in the sink
Don't leave a knife wet, even ones claiming to be stainless will often rust if left wet."
Sounds like you're doing it wrong. Line a baking sheet with foil, lay out the bacon in a single layer, and pop it into the oven. If you like chewy bacon, start with the oven cold, turn it to 400, and cook 15-17 minutes. if you like it crispy, start with a hot oven and 12-14 minutes. no splatters, ball up the foil afterward for easy cleanup, and done.
