Can obsidian break easy?

Obsidian's Characteristics

Blades crafted from obsidian are not only thinner but can also be up to five times sharper than those constructed with top-quality surgical steel. This exceptional sharpness enables surgeons to perform cuts with greater precision, resulting in reduced trauma and scarring to the skin. However, it is important to note that while obsidian can chip, scratch, and break quite easily, it remains a favored material for use in jewelry and artistic creations.
