Was reading this and got inspired:
Axe of BoomBase Weapon:Tomahawk (throwing axe)
Dmg: (STR/2)+2P
Weapon Modifications:Smartgun System
Advanced Safety (Explosive Self-destruct, 10P flechette, 5 AP, blast -2/m Radius)
Gecko Grip
Wireless Adapter (dunno if this is needed)
Throw axe, hit, do damage, laugh manically, remotely trigger the axe's self destruct.
The Gecko Grip is there to make the axe harder to pull out once it hits, plus you can "store" axes ready for use just by sticking them to your body.
All for under a thousand nuyen a pop.
