Is your knife sharp?

Magazine test - Slice a folded magazine page. A sharp blade will easily slice the paper, a dull blade will not.

Food test - The ultimate edge will grab onto the skin of a tomato or onion. If the blade slides off the edge (or pressure is required), it's dull.

 

 

Supplies

If you are new to sharpening, all that you need is a hone and a stone to get started.

Japanese water stones are simple to use and provide excellent control to obtain a razor sharp edge.

 

 

 

 

Honing 101 

A hone is a regular maintenance tool to be used as often as you feel necessary. Its purpose is to align the blade's edge and increases efficiency. The trick is right pressure and right angle.

Pressure - Grab your knife by the handle and press the blade on a kitchen scale until you reach 4-6lbs of pressure. 

Angle - Hold the blade against the hone and place a matchbook in between the hone and the blade (12-15 degree angle). See image (left) as a guide.

 

 

 

Honing, Step-by-Step 

1) Anchor the tip of the hone on a cutting board.

2) Place the edge of the blade against the hone at a 12-15 degree angle.

3) Put your finger at the heel of the blade, and press into the steel.

4) Keeping the angle, pull the blade down in an arching motion from heel to tip.

5) Repeat 4-8 times on each side of the blade, moving from moderate pressure (4-6lbs) to lighter pressure.

6) When finished, do the magazine test or onion test to check your work.

 

 

Water Stones

When the hone no longer brings the edge back to the level of sharpness you desire, it is time to use a water stone to make a new edge.

Start with a lower grit stone (removes material and makes a bur or wire edge). Then move to a higher grit stone to polish.

The trick is maintaining a consistent angle and keeping even pressure across the blade (see guides for honing above).

 

 

Using a Water Stone, Step-by-Step

Preparing the Wet Stone

Determine if your stone needs to be soaked by squirting water on the surface -- if it absorbs then it needs to soak: 

- Submerge the stone in water for 10 minutes. 
- When the bubbles stop, take the stone out of the water and set the stone on a flat surface.

Super Stones do not need to soak. Simply wet the stone's surface, and you're ready to go.


Stoning the Blade

Use the same 12-15 degree angle as with the hone.

If you're right handed, hold the handle in your right hand and spread your left fingers across the blade for even pressure.

Keeping that angle, move the blade straight back and forth or make an arcing motion across the stone (pull the knife towards you, heel to tip, making a swooping motion on the stone).

Start with about 4-6lbs and end with about 2-3lbs of even pressure across the blade. 

Flip the blade and repeat on the other side.

When you can feel the wire edge, it's time to move to a finer grit stone to polish.


Polishing the Blade

With a finer grit stone, repeat as above, lightening pressure as you go.

After using the finer grit stone and while it is still wet, scrub it with the Gold stone to create a slurry on the surface for extra polish. Then, repeat as above with light pressure.

When you're finished, wipe the metal residue off of your blade, rinse and dry the stones.

 

         

 

 

How to care for your water stones 

Maintenance

Keep your stones clean and cutting easily. The finer grit stones (1000 grit and higher) build metal residue that needs to be cleaned. After using the stone, and while still wet, scrub with the Gold Surfacing stone. This will create a 'slurry' on the surface. Sharpen the blade for a few strokes in the slurry for extra polish.

Keep your stone flat. Wet stones tend to wear more in the center, which needs to be corrected for even sharpening. Wet the stone and rub with the Blue Ceramic Flattening stone until flat (you can also use a sheet of silicon carbide sandpaper on a flat surface with a little water on the back).

Cleaning

Rinse with cold or luke warm water and air dry your stone before storing. Do not use hot water, soap or dry with a fan. Doing so may damage the stone.

Storage

Wet stones should be stored indoors room temperature in a clean, dry place. Do not store in water, direct sunlight or the cold garage.

 

 

Stropping for the final touch

These strops are set up in two stages to remove any remaining burr or wire edge and to give a very fine high polish to the blade's edge.

The following description is a general suggestion for achieving a high polished edge but you may want to experiment once you become comfortable with how the strops work.

Leather Strops

There are two leather strops (rough and smooth) backed with a rubberized magnetic backing. The side marked "mag" goes on to the steel base.

Important Tips

- Go slow and easy with light pressure. Stropping does not require a lot of pressure. 
- ALWAYS move the knife in a 'backwards motion' on the strop. Do NOT push the edge into the leather. 
- Use the same 12-15 degree angle and approx. 4-6lbs of pressure.

 

 

Stropping, Step-by-Step 

Rub the green chromium oxide over the 'rough' leather strop.

Remember to drag the knife BACKWARDS on the strop.

On the 'rough' leather strop your blade 5-10 times on each side.

Now switch out the rough strop with the smooth strop on the steel base.

It is not important to use the green abrasive with this strop simply strop the knife again BACKWARDS 5-10 strokes per side.

You should now have a highly polished edge.
