A sharp knife makes any task easier. But we don't always have the time or skill to sharpen like the pro's do, so here is an easy and effective method. Using a stick weldingelectrode/rod is easy and quick. It won't replicate the results from a oil- or waterstone, but it will keep you working when your knife has dulled.
Normal mild steel electrodes work fine, but if you can get those black or blue hard-facing rods, even better.
Step 1: One Knife, One Electrode.
Get your hardworking knife and the electrode of your choice.
Step 2: Technique
Hold the electrode at the tip and press the other tip to your hip. Now stroke the blade at a very flat angle over the electrode. Start from the hilt and slide the blade along the electrode, drawing to the side along the length of the blade. Press the knife down hard enough to create some friction, but don't buckle the electrode.
Step 3: Change Direction.
Turn the knife over and start from the hilt again. Maintain the same flat angle, only slightly higher than the bevel of the blade. Slide it back towards you drawing the full length of the blade over as much of the electrode's length as you can safely use.
Step 4: Repeat.
Repeat this about 10 times. Carefully feel the edge with your finger to check for a burr. Repeat steps 2 and 3 if necessary to get the result you desire. Remember, this is not an exact science, but it will give you a functional knife.
Step 5: Test Your Tool.
Slice something. I cut a fillet from this very deserving, evil tomato.
Please be careful with the sharp stuff.
