Talk about the "Jennings Pattern" bit reminded me of part of a page I cut-and-pasted from a vintage hdw. comp. catalog. Sorry, I don't have the date of the catalog at my mental fingertips. Too, I've yet to go through all my auger bits to see if I agree with Strelinger's rap on the two patterns, but I thought youse might be interested in it. Too, check the pricing of one of each; say, the 1/4" dia.
Do you think the "genuine" was worth 50% more? That argument seems to lose to price every time. Domestic vs foreign, union vs open, local vs Walmart etc.
I like quality. I would really like to know, first hand, how well tge original performed vs. the copy.
