Indeed. You need to build a grinder on the assembly area next to the fence. Click the book there and select the blueprint. It is one of the ones unlocked when you inherit the workshop.

For materials, you need two copper bars per copper blade. You can make copper bars in a stone furnace (also built on the assembly area) and you'll find copper ore in Abandoned Ruins no. 1 at the foot of the mountain where the church is located.
