Which chisel is specifically utilized to chip mortar from joints?

The plugging chisel is designed specifically for the purpose of chiseling and removing mortar from joints. Its construction features a sharp edge that enables it to easily penetrate and break apart hardened mortar, making it particularly effective for this task. The tool's shape and sharpness are optimized for precision in working along mortar joints without damaging the surrounding masonry.

In contrast, the other types of chisels have distinct uses; for instance, the pointing chisel is generally utilized for shaping and dressing brick or stone, while the cold chisel is primarily intended for cutting metal or hard materials. The tapered chisel, on the other hand, is typically used for fine, detailed work and may not be as effective for the specific task of chipping mortar. Understanding the purpose and design of each chisel helps in selecting the correct tool for masonry projects.
