What is a cursed tool

you find them in the 3rd mine under ground (you have to till the ground, some times there under rocks so get rid of rocks and animals) you can not remove them from your rucksack until you get the cursed removed at the temple (by phone or face to face with the vicar in his temple) the tool is alot better after woulds. if it is cursed then it drains your stamina quickly and also drains time alot quicker where as if it's blessed it does the same effect as a normal tool. hope this helped thanks.
