No, iaito swords are specifically designed to have a non-sharpened or blunt edge. Unlike functional or live-blade swords, iaito swords are intentionally constructed with a flat or rounded edge for safety during iaido practice.

Iaito swords are made to replicate the look and feel of a katana, but they are not intended for cutting or combat purposes. The non-sharpened blade allows practitioners to perform repetitive drawing and sheathing techniques without the risk of accidental cuts or injuries. This design feature is crucial for the safe practice of iaido, where the focus is on form, precision, and control rather than cutting targets.

It's worth noting that while iaito swords do not have a sharpened edge, they still retain the weight, balance, and overall appearance of a traditional katana. This allows practitioners to develop proper technique, timing, and fluidity in their iaido movements while maintaining a safe training environment.

If you are looking for a functional sword with a sharpened edge for cutting exercises or other purposes, it is advisable to consider a different type of sword specifically designed for those applications. Functional swords, often referred to as shinken, are constructed differently and are made for cutting and combat use.
