Recently found that chainsaw is not suitable for shaving sheeps any more (didn't test it without GregTech), so maybe made an electric shaver for that purpose?
Shocker is hand device that does not cause a lot of damage, but will "knockback" and cast a "slowness" for 5 seconds on entity, enough to retreat and pickup a BFG9000 from a nearby chest. Perfect for fighting maniacs in the dungeons. )
