minus-squareSpaceNoodle@lemmy.worldlinkfedilinkarrow-up3·4 days agoHow does the handle have no “inner surface?”

minus-squareSpaceNoodle@lemmy.worldlinkfedilinkarrow-up1·4 days agoAh, I see. Well, it’s still a hole.
minus-squareSarah Valentine@pawb.sociallinkfedilinkarrow-up1·4 days agoYes, the hole through the handle loop. The person you were replying to was talking about a potential hole inside the handle itself.
minus-squareSpaceNoodle@lemmy.worldlinkfedilinkarrow-up1·4 days agoBut is that a hole, topologically? Sounds like a shell.
