• Extremely dull knives can be  

sharpened in Stage 1, but many 

strokes may be necessary. Stop 

periodically and check the blade for 

sharpness by carefully cutting paper. 

Then hone the knife in Stage 2.

• Avoid excessive downward pressure 

on blade. 

Resharpening

Knives can be resharpened by follow-

ing the procedure described above, 

but, generally, fewer strokes will be 

required than for the initial sharpening.

Maintenance

• The exterior can be cleaned with a 

damp, soft cloth.

• No oils or other lubricating liquids are 

necessary with this sharpener.

• Not for scissors
EdgeCraft also offers a wide range

*  To test periodically for sharpness, hold a sheet of paper  

by its edge, a short (but safe) distance from your 
fingers, and carefully slice through the sheet. A sharp 
blade will cut smoothly without tearing the paper.

1. Sharpening - Stage 1

Holding the knife in the right hand, 

place blade in the first slot (above 

number 1). Center the blade left to 

right in the slot. While keeping the 

blade well seated in the slot and  

continuously centered in the slot, 

move the blade back and forth 

smoothly along its entire length, 

through Stage 1. It is unnecessary to 

lift the blade after every stroke. Apply 

light downward pressure

 on the 

blade and continue the back and forth 

action until the blade is sharp. Stage 

1 creates a first bevel along the edge. 

Unless the knife is very dull, it will 

take less than 25 full back-and-forth 

strokes to sharpen in Stage 1. Do not 

proceed to Stage 2 until the edge is 

very sharp. It should, for example, be 

sharp enough to cut paper well*.

2. Honing - Stage 2

To hone the sharpened edge to razor 

sharpness, move the blade to the slot  

of Stage 2. This hones by creating a 

second “micro-bevel” along the edge. 

Maintaining the blade centered in the 

slot, move the blade back and forth 

through this slot. Apply little to 

no 

downward pressure

 on the blade. 

If the blade is sharpened adequately 

in Stage 1, only a few, (less than 10), 

strokes will be necessary in Stage 2.

Suggestions

• If left handed, turn the sharpener  

around, hold the handle with your  

right hand and the knife with your  

left, and follow sharpening and  

honing instructions above.
