This fence has a curl - shaped cross - section and is made from plastics or wood.
In the convex part of the curl, you put sand, salt or commercial slug repellent.
A slug creeps in, up the curl and into the convex part where it is either repelled or killed, depending on the filling.
The advantages
over normal fences are:
1. It looks unusual and original.
2. The filling keeps dry. All conventional anti - slug measures do not work when wet, which limits their usefulness in practice.
3. Snails can not creep over it, while they can overcome most other obstacles.
The fence has a portion extending into the ground, to keep slugs from burrowing through, of course.

Nothing, as long as they keep out of my salad. This is why this fence can be loaded with non-lethal stuff such as sand (they can not crawl over it, so they turn back) or slug repellent. |

|
could the slug "rear up" and stick onto the thing above the gap? |
|
|
I welcome ways to prevent these critters from eating my plants, but with a title like this, this idea should be for a novel form of bullet-proof vest - as a matter of fact, off to post. |

Copper has been shown to be an effective all-weather repellant. They're making all kinds of products out of it. Still, the fence looks kind of cool, and could hold other pesticides, adhesives, and whatnot. |

I notice that slugs can go the opposite way, by falling off the overhang. You can export your slugs to the neigbours. |

Slugs can't crawl across sand? |

Not very well - see link. |
