at the mention of door knob I now know what you are alking about. I inherited from a $5.00 box at an auction many odds and ends. this is a thing which goes in the end of I think a 3/8th drill. it feels like there could be several different sizes of a blade inserted in diffrent size circles. however different that what I am reading here so far t this one blade that I have , feels like more of a very small band saw blade . I wonder if this size blade can be bought as a individual item?Lee
