Here we go, As I mentioned here are pictures of my Paratech Top Cut axe, its matching Hoolian tool, and my Biel rescue tool
Ah, The Irons.
The flat head axe and Halligan bar (Married together and called The Irons) are the staple of forcible entry in most of the US fire service. The Halligan was invented in 1948 by Chief Hugh Halligan of the FDNY. His originals have his name in the casting and go for around $1K on eBay. I blew my chance to grab one for cheap around 10 years ago. Grrrrr.
The Halligan is designed to be able to be struck or pry in three different directions. Great tool. The Hooligan you have is a take off to avoid the Halligan name.
