Something to pay attention to ...
In my experiences, the magnetism transfers through the blade (metal swarth sticks to blade during sharpening and to itself) and pivot (metal swarth attracts to inside pivot assembly). Blade may need to be degaussed (aka de-magnetized) after sharpening to eliminate the blade & pivot continually attracting metallic dust in future (a horrid condition for anyone that uses grinding equipment).
I learned this years ago when installed neodymium magnets into the underside of table on EdgePro. I now reserve the use of magnetics during sharpening to clean-up duty AFTER sharpening.
It may take sharpening a few knives to notice the condition, comments here simply to make you aware of the potential.
Example of blade possibly in need of degaussing (less of an issue on knife w/o pivot assembly to trap/hold metal swarth):
