Another item from the Half Moon Bay meetup of PAST Tool Collectors.
This was free. As I was paying for the countersink bits, I spied it on the table and picked it up, saying “oh, wow, a countersink for wood! The ones today with the multiple flutes are largely for metal and are utterly horrible in wood. I would love to have this, how much?”
He threw it in for free. No charge. He only charged me for the other items I was buying at the time (previously seen in the series as the countersink drill bits).
It’s not a Millers Falls but I took a photo of it next to the Millers Falls entry on the similarly shaped item, called a single-lipped countersink.
