Hawkmate

This tool is awesome, I use it all the time. The hawkmate is a spackler’s hawk [tray for carrying mixed spackle] with a plate on its underside that holds the taping tools. I no longer have to hold multiple knives in my hand or in my pockets. Also when I put the tool in my truck the knives stay protected from chipping or bending.
