A fully automatic melee weapon powered by a miniature nuclear battery that drives a toothed chain along a grooved bar at up to 8,000 RPM. This allows the sharp teeth to shred virtually anything they come into contact with.
The version modified by the Gun Runners differs from its standard variant in being able to accept modifications. Compared to the standard, when fully modded, the GRA chainsaw deals more damage with the same attack rate, thus having a higher damage-per-second (DPS) value. It also has significantly higher durability and weighs less as well as having a significantly higher caps value.
Special attack[]
The GRA chainsaw has a specialScrap Heap attack, which does 50% damage in V.A.T.S. but at the cost of 20 less action points.
The chainsaw (GRA) can successfully strike about 7,995 times, or 11,995 times when equipped with the heavy duty chain, from full condition before breaking.
A fully upgraded chainsaw, with all related perks, is the second strongest melee weapon in the game, only surpassed by the thermic lance.
The damage and DPS displayed is counted for 1 second of continuous attacking. The critical damage, however, is counted for every damage tick. Those ticks happen tens of times per second and because of this, the chainsaw, along with other "hold down for continuous attack" melee weapons, is extremely strong with critical chance/damage bonuses. With no critical damage bonuses, difference between 0% and 20% critical chance is double the amount of damage displayed. With 100% crit chance the damage seems to be seven times the basic amount.
This weapon, like all other continuous attack (automatic) close combat weapons, has only its "start-up attack" animation sped up by attack speed bonuses, while damage dealing and DPS is completely unaffected.
Due to an engine bug, the Ignore DT/DR effect does not apply correctly and because of this, Piercing Strike gives a marked improvement in DPS.
