My vote is for the scapel blade seam ripper with replaceable blades, my Ott light, my needle threader for my serger, needle threader on my sewing machine, my brass stilletto, and last but not least is my needle trolley. By the way a needle trolley looks like a thimble with a needle soldered to it, it works like a stilletto but does not have to be picked-up and sat down like a stilleto. I would not have been able to complete my nephews dww quilt in time without it.
