One of the three improvements for the Shovel Blade the Charge Handle allows the use of a charged Dig Slash by holding down the attack button. When released the Dig Slash does two damage and pierces through most defenses (such as that of a Hoppicles or Goldarmor). On the other hand as long as the attack is charged Shovel Knight moves far slower unlike the charge attack given by the Dynamo Mail.
Amiibo Mode[]
The Charge Handle can only be used by Custom Knight by equipping the special move "Shovel Upgrades". However, using a different charge move will disable Charge Handle.
