"With the Severing Charm, cutting or tearing objects is a simple matter of wand control. The spell can be quite precise in skilled hands, and the Severing Charm is widely used in a variety of wizarding trades. Useful as it is, this charm should be practised with caution, as a careless swipe of the wand can cause injury."

— Miranda Goshawk

The Severing Charm (Diffindo) was a charm used to precisely and accurately cut something. It was taught in second year charms classes and Fourth year classes, and if used inappropriately can cause death or injury.

A spellbook for this charm could be found in one of the Herbology greenhouses; this was also detailed in both Book of Spells and The Standard Book of Spells, Grade 1.

History

"The Severing Charm was created in the fifteenth century by wizarding seamstress Delfina Crimp who created it as an easy and convenient way of cutting cloth and thread."

— Book of Spells

Delfina Crimp using this charm to shorten a dress

This spell was invented in the fifteenth century by seamstress and witch Delfina Crimp. She made the spell because prior to her discovery, cutting spells were apt to burn or shred things. However, a rival Muggle clothes maker, Snickerton, realised that she could do magic and raided her shop with friends. They held her tied up and nearly killed her. However, she convinced them to release her to scratch a wart on her chin. When allowed to do so, she drew it out, revealing the wart to be her hidden wand. She then disapparated with a sack of gold.

It is implied that Crimp may have continued to use it, or cast a curse on Snickerton with similar effects, as all of his subsequent creations were found sliced up.

Known uses

"“Diffindo!” Cedric’s bag split. Parchment, quills, and books spilled out of it onto the floor. Several bottles of ink smashed."
