Can a rod have a stab-safe tip?

Relevant bit of the wiki: profounddecisions.co.uk/empi … Implements

A staff that’s an implement may have a stab-safe tip, but what about a rod? I know, “email PD”, but I wondered if anyone had done it already

No.

No weapons under 5ft can have stab-tips.

Is that “may not be constructed with” or “may not be used to thrust even if constructed with”?

The latter.
