Not that long ago, most every station (CDF) had a device usually mounted to the floor of the ap bay, that would hold all the hand tools for sharpening. All the ones I remember were “home made”, from a piece of 6″ x 1 1/2″ channel iron about 18″ long. It had various notches cut into the channel and screw clamps to hold the tools This device was invented by Fire Captain Newman and bears his name. He worked in HUU probably in the mid 70’s. It is still referenced in the 4300 manual but no one seems to know what it is. I am looking for any information about the device or Captain Newman, photos, or the actual tool.
