A hammer. So called due to the difficulty faced when our dextrousley challenged chums, fancy a spot of D.I.Y

Hey fergus, chuck us that Irish Screwdriver, Im having a wee spot of bother with this nail!

Irish screwdriver 

A hammer. From an old joke about an Irish labourer talking to his boss.

"How'd you get them screws driven in so fast Paddy?"
"Oi used an 'ammer sir, et were much faster."

"it's not working"

"use an irish screwdriver then"
