The last enchantment was eventually removed and transferred to Stormbreaker, the hammer of character Beta Ray Bill. After this the Donald Blake persona disappeared (eventually returning from the after life ), and Thor assumed a civilian identity simply by changing into modern clothing (carrying Mjolnir concealed within a duffel bag). Thor eventually adopts the mortal persona of Jake Olson as penance for accidentally causing the original Olson's death during a battle, and simply pounds a fist to effect a change. During this period Mjolnir would disappear when Thor became Olson, and reappear when returning to his true form. Thor was also once again bound by the original rule whereby he would revert to Olson if kept away from Mjolnir for more than a minute.
