It is a compact pocket sharpening stone with diamond surface on both sides. In the middle of one side there is a special groove for sharpening pointed objects such as fish hooks. It comes with practical leather pouch.
Step 1 - place the stone between thumb and forefinger or middle finger
Step 2 - place the blade´s edge against the flat side of the stone and gently sharpen using single stroke (as if you were attempting to slice a thin layer off the side of the sharpener); Maintain consistent angle and use a gentle pressure
Step 3 - stroke 3 - 5 times and then repeat this on the other side of the blade
Step 4 - continue until the blade is sharp
Step 5 - for sharpening fish hooks or other pointed objects use hollow lines.
Same use for both righ and left-handers.
Note:
Read the instructions before use. Do not rush and pay attention to
what you do.
Knife sharpening is an inherently dangerous activity - if you use this
sharpener properly you can not be hurt but a careless handling or pointed objects can hurt you.
