So LOML is learning basketry, and there are a few tools specific to the craft, one of them being a fid. It's similar to an awl, but has a slightly blunt tip, and tapers flat on the sides, while swelling slightly on the rounded sides, so that one can insert it between slats, and turn 90 degrees to open a small space.
I started with some 3/16" steel rod, and shaped it with hammer, file and sandpaper. The handle is a pretty piece of curly maple rescued from our firewood pile. Brass ferrule from LV.
