Titanium Halligan

Tico Titanium makes a halligan bar out of titanium.  Half the weight of steel - less then 6 pounds... but more than twice the cost- $600.  ($610 for the 30 inch model with eyelets for a strap)

The reduced weight would be great for lugging around, but when it comes to driving the claw into a door jamb or other tight space, that weight of the bar might be missed.

Cool Tools:

This is a great tool if you live in earthquake country, or for first-responder firefighting or rescue folks. I imagine that with a sledge hammer, gloves, and this tool you could tear apart a whole woodframe house in a matter of hours. Everything you need is in the box, including the big Phillips-head screwdriver and adjustable wrench you might need for switching configurations around.
