You think you'd get bits of gill, fins and scales all over the place.
Well, that would be better than the other sort of pike, which was used in a historical battle re-enactment in Birstall over the weekend.
A pike, for those who don't know much about medieval armoury, is a long stick with a spear on the end.
They were used by soldiers for hundreds of years.
Then some bright spark put a hook on the side of the pike's head, so soldiers could cut the reins of horses in order to dismount the rider.
Charming. But enough of the weaponry lesson.
The Sealed Knot, the English Civil War re-enactment society, was at Oakwell Country Park over the weekend as part of National Archaeology Week.
Military camps were set up on the front lawn of the hall and visitors could see the day-to-day life, military drills and occasional skirmish between Royalist and Parliamentarian forces.
Both days built to a climax, with a spectacular re-enactment of the Battle of Adwalton Moor.
The original battle took place in 1643 and saw Parliamentarian forces led by Fernando Fairfax, the second Baron of Cameron, outnumbered two to one by the royal army under the command of the Duke of Newcastle, William Cavendish.
The two armies met on the ridge overlooking Adwalton Moor.
The Parliamentarians drove off several assaults by the Royalists, but the undisciplined Parliamentarians then broke ranks and found themselves outflanked and attacked from both sides.
What was left of the defeated Parliamentarians withdrew to Bradford.
David Oxley, of the Earl of Manchester's Regiment, said he had got into the Sealed Knot after seeing a previous display.
Mr Oxley, a senior nurse in his day job, said: "You have a great social life with the Sealed Knot.
"There is a great sense of camaraderie and mucking in together.
"It's also very good for the history. Younger people who weren't interested in history at school have said that seeing it presented like this really makes it come alive."
