Not all fix-its can be done in the home workshop, and for those times when you have to carry tools to various parts of the house or garden, make yourself a simple carrying box.
First assemble the bottom and four sides with nails. The sides can be as deep or shallow, or tapered or straight, as you prefer. Cut the center panel which acts as a divider inside the box.
With a coping saw make an opening through which your fingers will fit, to carry the box.
Place the partition in center of the box, and attach it with nails through the bottom of box and the two end boards. Sandpaper all surfaces smooth.
