OPERATING THE UTILITY SHARPENER (cont.) 

12.  If the item to be sharpened is in good condition, then proceed to lay the item flat on either of the 

tool rests as shown in Fig. D. Loosen the lock knobs and adjust the tool rest until the original bevel 
angle of the item to be sharpened is matched. Maintain a 1/8” distance from the grinding wheel 
after the tool rest has been adjusted to the proper angle. Firmly tighten the lock knobs. 

 

NOTE: 

To sharpen scissors, hold as shown in Fig. E. You must sharpen the bevel side of each scissors 

 

blade. 

DO NOT 

attempt to sharpen the flat side of the blade. This will ruin the scissors. 

 

 

 

 

 

 

 

13.  Practice a few times while the Utility Sharpener is 

OFF, 

slowly pulling the tool across the grinding 

wheel while keeping the tool flat on the tool rest. 

ALWAYS 

pull the item to be sharpened across the 

wheel from the angle to the tip of the blade. 

DO NOT 

ever push the item across the grinding wheel. 

14.  Plug the power cord in to the electrical receptacle and turn 

ON 

the Utility Sharpener. Ordinarily, 

cutting edges are sharpened with the grinding wheel turning toward the blade. However, if you find 
it more comfortable, you may sharpen with the wheel turning away from the blade. 

15.  Proceed to lay the item to be sharpened flat onto the tool rest and hold onto it firmly with both 

hands. Slowly and lightly pull the item across the rotating grinding wheel. Inspect the item after a 
few passes to check the progress. The cutting edge should have a shiny appearance the entire 
length of the cutting surface. If the surface has dark and shiny spots, the angle of the tool rest is not 
properly adjusted or the user is not keeping the item flat on the tool rest. Make adjustments as nec-
essary. 

16.  Alternate sharpening on both sides of the tool. 

17.  Upon completing the sharpening operations, a small burr might form on the cutting edge. Remove 

the burr by turning the Utility Sharpener 

OFF 

and unplugging it from the electrical receptacle. Light-

ly pull the blade across the stationary grinding wheel until the small burr is removed. 

18.  Dump out the water that was poured into the water trough earlier by tilting the Utility Sharpener 

backward. 

19.  Wipe the Utility Sharpener off with a clean dry rag and inspect for any damage to the grinding 

wheel.
