Seeing the "wooden object brought back many wonderful memories of so many years ago.
The object, in those days was called a Slider. In our woodworking class the construction of a Slider had to be completed to the satisfaction of the teacher before we could attempt more ambitious projects.
To complete a Slider, the student would have to use just about all of the hand tools in the shop.
I can remember Mr. Catino with his hands behind his back walking around the class observing our progress or in many cases, our lack of progress.
After the Slider was complete, it was use to "hold an angle" that is to move the small blade, measure an angle and then transfer that angle to the project you were working on. It was, after all a very useful tool.
Many of us having completed our Sliders would carve our initials into the bottom and carry them in our pockets with pride.
Thanks for the reminder of the Slider.
