This script removes all sheathes the player decides to wear, so no knife sheaths or even the knife will show. This is script is different from removing it in the wardrobe because the second you change outfits in the wardrobe, then it wil become visible again due to how rockstar coded the outfits to work. This script always makes sure it stays removed.
Special thanks to SgtJoe from the modding community to provide the script!!!!

Just copy it to your RDR2 directory!!
