Secrets to a Long Lasting 
SharperBlade
™
CONGRATULATIONS! You are about to experience a faster, 
easier way of grooming your lawns edge and managing weeds.
First, you will notice that there are obvious dierences between 
your SharperBlade
™
 and string line, among which are size and 
shape. These dierences require you to operate your trimmer + 
edger slightly dierent:
1.  Use MINIMAL pressure when edging against concrete, 
brick, or stone. Since the SharperBlade
™
 is more rigid than 
string, you may feel the need to put pressure on the blade 
while edging. The more pressure you apply, the FASTER 
the blade will wear. In contrast, the less pressure you 
apply against hard surfaces, the LONGER the blade will 
last! The SECRET is to keep the blade just o the  
hard surface.
2.  NEVER FORCE your SharperBlade
™
. High speed, along 
with an impact against any hard surface, may cause the 
blade to buckle near the center hub, and tear. 
The SECRET is to allow the SharperBlade
™
 to do ALL the 
work without extra eort.

™
 cordless grass trimmer +
