The cutter, as received, has a cut Persona prep blade taped to the fence. This is the verification blade done to ensure the cutter performs as designed.

Caution: If not using Personna prep blades, be certain the blades you are going to cut are not too hard. They will crack along the cut line and could chip the cutter. Contact us if in doubt.

We have found the current supply of Personna blades may have more oil on them than in the past. I suggest carefully wiping the oil from the blades after the back has been removed to minimize the cut recipient site blade sticking to the cutter.

Beginning to cut blades

The fence on the cutter slides left and right.

With the cutter in the closed position, set the fence to the 90 degree position and slide to the right until it just touches the cutter top blade. Tighten the screw on the fence finger tight. This step is not necessary for the angles other than 90 degrees.

Lay a piece of paper under the cutter. This will catch the blades and allow you to easily feed them into the organizer tray. Best results will occur if you remove cut blades from under the cutter as they are cut. Loosen the knurled screw on the width adjustment link. Push down the width adjustment link with your fingers about 12mm (1 /2 inch) . This moves the blade stop and allows the notched end of the blade to be removed in 1 cut.

It is very important to remove the notched end in one piece to prevent the little chips from hanging up and chipping the cutter .

Place the blade against the fence and into the blade grove with the sharp side up, be careful not to touch the sharp edge of the prep blade. Lift the handle and slide the prep blade in just far enough to remove the notched end.

Be certain to keep finger force down on the blade during cutting. Failure to press down may permit the blade to lift causing cutter damage and the blade may squirm and the cut blade will be tapered. To cut, push the handle away from yourself gently and smoothly as far as it will go and discard the cut off notched end. Pull the width adjustment link up until it cannot be pulled up any higher, and re tighten the link lock screw. This replaces the blade stop.

Scalpel blade cutting angle

Loosen the stainless steel screw on the blade fence. Lift the left end of the fence and drop into the desired hole to adjust the angle 90, 60, 45 or 30 degrees. Tighten the screw with your fingers.

Scalpel blade width adjustment

Adjust the scalpel blade width by turning the blue adjuster knob. This will be pre set for one millimeter. Turn clockwise for narrower blades, and counter clockwise for wider blades. Blade widths are marked on the knob. Line up the number with mark on the adjustment link. The blade width adjustment knob is marked from .5mm to 1.4 mm. If larger widths are desired, continue turning the width adjustment knob counter clockwise adding 1mm to the graduation on the knob. Pull the handle back until the prep blade will slide under the cutting blades, slide the prep blade in until you hit the stop.

The cutting fence has a shallow recess under the upper edge to help prevent the prep blade from lifting while cutting. Never the less, keep even pressure on the blade so it doesn’t slide around, and push the handle away from yourself until the blade is completely cut. Use a slow steady movement. You will feel the blade being cut smoothly. Do not use a quick jerky movement as this will prevent you feeling a potential double cut and there will not be time to stop cutting. Continue this process until you are satisfied with the number of blades cut. It is very important to pull the handle far enough back for each cut to ensure the prep blade contacts the width stop and the cut blade drops from under the cutter top blade.


If cutting force suddenly increases, stop and see if a previously cut blade, or part of a blade, has become trapped on top of the uncut blade. Do not try to cut through two thickness. Cutter damage will result.

If you are cutting blades less than 0.9mm or thinner than the Personna prep blade, you may find them not falling out of the cutter as easily as wider heavier blades.

Check the paper under the cutter to see that the cut blade has dropped out. If the blade has hung up, depress the stop arm a little. The blade should drop out. Reposition the stop arm and cut the next blade.
