[RPG] What are the consequences of damaging a portable hole

dnd-5emagic-items

After asking a question about stitching a portable hole, and reading the DMG last night, I couldn't find any information on what happens to a portable hole if it's damaged.

I could assume the effects of damaging a Bag of Holding (the contents spilling onto the astral plane), but are there any defined effects of damage to or destruction of a portable hole, while in its unopened folded state?

From the DMG p.141:

Magic Item Resilience

... Most magic items, other than potions and scrolls, have resistance to all damage. Artifacts are practically indestructible, requiring extraordinary measures to destroy.

The Portable Hole isn't an artifact (q.v. DMG 219), so it only requires ordinary measures to destroy. It does take twice as long to destroy as a non-magical hole (hah!), but that's as far as the DMG takes us.

So any mutilation of your Portable Hole is going to go outside RAW, and you'll have to work with your DM to figure out if, how, and any consequences. (The effects you mention from Bag of Holding are certainly suggestive and may inform this discussion, but are not controlling.)
