Harrison Nash Wells' blaster is a weapon used by Harrison Nash Wells.
When Nash and Joe were stuck in a cave-in in the sewers, he tried to use the blaster to blow up the rocks. However, due to Earth-1 is vibrating at a different frequency, it only caused fire and reduced their air supply.
- Vibrational frequency: The blaster does not work properly when it is used on an Earth with a different frequency. The blaster will cause a fire instead of a laser blast.
