Armourial pun

Well, after the incident with the electro-magnet, the Archdruid (who's a great fan of P. G. Wodehouse, of course) decided that the Piper should let bygones by bygones, and should give up his shin protectors. She immediately had them fashioned into digging implements: rather along the lines of swords into ploughshares.

I know what you're thinking: "What, hoe-greaves?".

I'm sorry.
