Identify Tool

Hello, my name is Bill & I am new here. I am in the Buffalo, NY area. I stumbled upon a KRW tool that has performed well for me in a non-traditional way, in pulling/pushing a pulley wheel off of the arbor of a 16" wood jointer. An example of the tool is shown in your photo section on "board 16", on the right edge of the display, a bit below center. The tool is marked "KRW" on both front and rear sides of one arm. The other arm is marked w/"AATA 2" on both sides of the arm. What does AATA 2 stand for? I'll post up a photo asap. I paid $5.00 for the tool in an antique shop in Tonawanda.
