I cut copper laminate for making printed circuit boards by scoring it deeply

oilstone. I've been using the same blade for months.

I keep telling SWMBO, "I'm not cheap, I'm just value oriented.", but
last Chanuka she got me a little porcelain figurine of Disney's Scrooge
McDuck anyway. I was born at the end of the great depression and learned
how to make do before america became a "disposable" economy.

I never had great success sharpening utility knife blades on a stone,
but once I got a 320 grit "diamond file" with a working area about 3/4"
wide by 2" long, WHAT a difference. A couple of strokes on either side
of the blade and it's good enough for me.

Thanks for the mammaries,

rubbing them around the inside of a straight sided drinking glass.)
