Your routine reminder: the weapon used to murder Henry Nowak was not a traditional Sikh ceremonial kirpan, but rather an Indo-Persian dagger known as a pesh-kabz.
Prominent Sikh organizations, such as the Sikh Federation UK and the Network of Sikh Organisations, have explicitly stated that the knife used in the attack was not a kirpan. Instead, experts have identified it as a pesh-kabz. This historical Indo-Persian blade was originally engineered for warfare to pierce through chainmail and heavy body armour.
The trial judge described it as a โlarge Sikh daggerโ. It wasn't. The murderous Vickrum Digwa was carrying an illegal weapon, not covered by any religious exemption.
