Bend an pegboard holder into a corner shape by holding it in a vise and pounding it with a hammer to make the series of right angles. Make one corner to hold the left side of the tool and another to hold the right.
Pegboard Shelves store a lot of tools with only two pegs. Bend the pegs to about 85 degrees. Use 1 x 3 boards for shelves, customize slots for tools, drill peg holes from end, hammer pegs in, make sure they fit tightly.
