Those old B&D are the real deal. Worst tool mistake I ever made was letting mine go.
Those who worry about the cords and grounding of metal housing power tools are correct to do so, but in sixty years of working with them, I've never had a problem. So far, so good.

I did have a problem with my old Port-A-Band- All aluminum construction, and get this; there was nothing wrong with the saw itself, properly grounded etc. There was an improperly wired drill press, (****** import) plugged into the same circuit, and I was cutting off a cyclone fence post, (read WELL grounded) and every time I started to cut, I'd get shocked. Nothing big but clearly not right...
I finally traced it back to the DP un plugged it and tried again. no shocking feeling. I finally traced it to where, IIR (Almost 30 years ago...) they really didn't see the difference between ground and neutral and the plug itself was wired backwards, and it was back feeding to me.
ALWAYS recheck old tools cause you never know...
Another potentially bad experience, was a few years ago we were replacing all the receptacles in a house my buddy lived in previously, then it was a rental for near 20 years. About 1/2 the receptacles were wired bas-acwards, and that could have been disastrous...
Most recently my next door neighbor (an old school marm literally..) complained the one of her receptacles was out and she could not find the issue with the breakers. Someone had actually daisy chained in another lamp and that one was out. I happened to plug in a night light to test the plugs we suspected were on the circuit, and the "dead" plug came on. so the plugs were wired in series not parallel...
The point being, Check ANYTHING someone else may have mucked with or is old and know the difference between Line power and neutral (And ground for that matter

)when wiring things up, because it CAN matter...
The best couple of bucks you can spend is one of those idiot light "circuit testers' that will tell you if a plug is wired properly. And the matter is made even simpler if you simply remember green screws are ground, the Neutral (White) goes to the silver screws, and the Line (black) to the brass/gold screws on outlets...
