The hammer heads are 3” cut from a 2×2 with a 3/4”dowel for a handle. I clamped a stop block on the drill press, drilled 3/4” deep, added some glue and hammered in the dowel (no nails or screws used in this project).
The screwdriver handles are 1” dowel 3” long with 5/8” dowel drilled and glued in place. I cut the flat heads on the band saw. The 5/8” dowels are 3 1/4” long set in the handle 3/4”. I made a jig out of 1/2 plywood to mark the dowel centres and to hold the dowel on the drill press.
I sanded down the edges and corners.
