i got this swamprat custom shop piece made of 154cm at BLADE and it has been magnetic from day one.dont know why but its cool.
somebody in the shop has to have some idea what this is from and why some and not others.
i highly doubt it means their is any defect in the blade such as an air bubble or anything else that would be a problem but i am very curious.i doubt it has any efect at all on the blades performance or longevity.
