how to make my entity affect other entities EXCEPT the entity/player that spawned it

how to make my custom entity, for example, affect other entities EXCEPT the entity/player that spawned this entity (if you spawn it through the entity spawn procedure). for example, I made a mob a circular saw, and in fact it should in the radius of 2 blocks to cause damage to other entities, except for me, if I spawned it through some kind of key.
