Always clean the blade free of dirt, oil and food before inserting into sharpener.
Before you turn on the power, slip a knife blade smoothly into the slot between the left angle
guide of Stage 1 and the plastic spring. Do not twist the knife. (See Figure 3.)
Move the blade down in the slot until you feel it contact the diamond disk. Pull it towards you
lifting the handle slightly as you approach the tip. This will give you a feel for the spring tension.
Remove the knife and press the Power Switch. A red “indicator” on the switch appears when
this switch is turned “ON.”
Stage 1: If you are sharpening a straight-edge knife for the first time, start in Stage 1. Pull
the knife once through the left slot of Stage 1 (Figure 3) by slipping the blade between the left
plastic angle guide and the plastic spring while pulling the blade toward you and simultaneously
moving the blade downward in the slot until it engages the diamond coated disk. You will hear
it make contact with the disk. If the blade is curved, lift the handle just enough as you sharpen
near the tip of the knife to keep the blade edge in audible contact with the rotating disk. Sharpen
the entire blade length. For an eight (8) inch blade each pull should take about 6 seconds. Pull
shorter blades through in 3-4 seconds.
