Accursed Items
The idea of accursed items comes from:
Deuteronomy 7:26 Do not bring any detestable objects into your home, for then you will be destroyed, just like them. You must utterly detest such things, for they are set apart for destruction.
I will link to a few videos of deliverance ministries going over items they encountered in their ministry.

While these videos are repetitive. I personally found them very interesting and helpful. Of course as with everything always lean on the Holy Spirit to guide you.

I just want to add that I personally do not cast demons into the abyss. Jesus himself allowed the demons to enter the herd of pigs, as it was not their assigned time for torment. So I personally do not feel like I have the authority to determine where they should go. I use the phrase "go wherever the Lord Jesus tells/or sends you" instead.
