 Re @-@ appearing in " Kir 'Shara " were the traditional Vulcan weapon , the lirpa , which was first introduced in The Original Series episode " Amok Time " . The lirpa is a long shaft with a crescent blade on one end and a spiked <unk> on the other . Brand new props were built for this episode , <unk> the original design by making them more lightweight . They were wielded in " Kir 'Shara " by Vulcan commandos , who were all played by stunt actors in non @-@ speaking roles . Additional stunt doubles were required for Archer , T 'Pol , T 'Pau and Talok while two puppeteers were needed for the Andorian <unk> seen on screen .
