Pine is a softwood.

Balsa is a hardwood.

"Softwoods are not necessarily softer than hardwoods. In both groups there is an enormous variation in actual wood hardness, with the range in density in hardwoods completely including that of softwoods; some hardwoods (e.g. balsa) are softer than most softwoods, while the hardest hardwoods are much harder than any softwood. The woods of longleaf pine, douglas fir, and yew are much harder in the mechanical sense than several hardwoods."
