What he wore, might have saved his life.
The whole incident was caught on surveillance video.
"The adrenaline rush still hasn't gone down," Abby Dumoff said.
That's understandable, as the surveillance video shows, graphic designer Abby Dumoff coming face to face with a scissor wielding robber, and winning the round.
"I didn't want to hurt him, I just wanted to get him out of the store without my computer," Dumoff said.
He works overnights at a copy store in Murray Hill.
Late last week, he locked the door, which has had problems, and took his dog for a walk.
He came back to find an intruder inside.
The intruder unsuccessfully tried to steal two computers that are bolted down and then headed to the cash register.
"I said something like, "You've got to get the hell out of here'," Dumoff said.
The robber then tried to carry out an expensive MAC computer.
"If when I come in I see him with a weapon of some sort, take whatever you want, but his hands are full with my computer," Dumoff said.
"You're determined," Eyewitness News reporter Sarah Wallace said.
"It's just not going to happen," Dumoff added.
Dumoff says the intruder threatened him with a non-existent gun, and he fought back.
"I put my arm around his neck and I'm prying him away from my computer," Dumoff said, "When I got him apart from the computer, the scissors appeared."
"Now, he's stabbing at me with the scissors, at my head and at my side," Dumoff described.
"Do you think the jacket helped?" Wallace asked.
"The jacket was everything," Dumoff said.
It even helped pad the fall as Dumoff fought the intruder to the floor and put him in a headlock.
"I grabbed him by the collar and dragged him out of the store and that's one of the things you can see most clearly on the surveillance video," Dumoff said.
And the drama continues; Dumoff. The loyal employee, pulls the computer away, gets inside, and locks the door.
But, his attacker kept on coming, trying to using the scissors to jimmy the lock.
"I hit the light switch here, and with the phone in my hand, and he took off," Dumoff said.
Detectives did ask Dumoff to look at a number of photos but he was unable to identify anyone.
Cops are hoping that someone will come forward after seeing the surveillance video.
