Q. We have a hand blender that we haven’t used in several years. we think it is meat but can’t quite remember, possibly is dairy.
The top half is a motor, bottom comes off for washing, and made of a plastic body and steel blade.
what is the status?

A. Horav Shlomo Miller’s Shlit”a opinion is that since the hand blender was likely used cold and such long time has already passed, the descending metal blade can be kashered and the blender used. From the shaile it seems to be that it was most likely used for meat, so that should be the recommended use.
