Shims And Wedges are a kind of manual tools that uses manpower to impact the metal wedge into holes on stone, thereby split stone. It is mainly used in splitting cracked stone and arch stone which by utilizing a wedge set can be separated into smaller or standard stone blocks. Wedge can also trim relative large and irregular stone blocks.

Each set shims and wedges consist of a metal wedge (the plug), and two shims (the feathers). The feathers are wide at the bottom, and tapered and curved at the top. When the two feathers are placed on either side of the plug, the combined width of the set is the same at both ends. The depth of drilled hole depends on the length of wedge.
