Mr Davids was on his way to visit a mate and spend the rainy day playing PlayStation until the freak accident left him impaled.
He told the Herald from North Shore Hospital he felt a piercing pain but nothing severe, so figured it was only his jeans that were caught.
"I was trying to yank them, trying to get free, when I realised my leg was caught more than just my jeans.
"There was a bit of pain around the area but I thought it was just the jeans that got caught."
The panic set in when he realised the spike was sticking into his thigh. "I was hanging there for 10 minutes and started yelling when I couldn't get free.
"My jeans looked to be free but I wasn't going anywhere. That's when I started to freak."
His mates inside eventually heard his calls for help. His first reaction was to get free as his mates held him up.
"I was just going to rip it out. At first I just wanted to lift me off and rip it out but one of the boys was smart enough and said not to.
"Lucky he said something, we were just going to yank it off. I was already putting my hand at the bottom of the spike and trying to lift the skin up."
He had surgery on Sunday night to remove the spike and will have the wound closed today.
Mr Davids was shown a scan that showed how close the spike came to a crucial artery and nerves. "It showed it [the spike] just pushed it out of the way and didn't go in."
He'd been told if the spike hit the artery he could have bled out quickly and realises how lucky he was.
The pain didn't start until the spike was sawn off the fence and he could feel the injury - and it moving inside him. "That's when the pain was there ... Because I was moving around and it was still attached to me."
The builder's apprentice and kickboxer said he had definitely learned his lesson and wouldn't be trying to leap over any fences in the future. And he won't be keeping the spike as a souvenir either.
"I'm going to give it back so they can weld it back on."
