Hardened Atom spring
steel cross blades absorb
shock when rocks and
hard objects are hit,
ensuring long edger life.
Non-Atom edger blades do not absorb shock
due to solid stiff construction. Gear and edger
life is reduced. NO WARRANTY allowed if
damage to Atom unit caused by use of non
genuine Atom parts.
