Should you use different blade other then the blade that come with the lawn edger

Hello Kevin, Thank you for your question. Only the blades designed for use with the lawn edger should be used. Use of alternative blades could result in damage to the unit or severe injury. Use of alternative blades could also result in the voiding of any available warranty. If you have questions about a specific blade compatibility, please feel free to reach out to our Customer Support Team at 888-436-3722. Thanks!
