CONGRATULATIONS
You are the owner of the world’s finest scissors sharpener designed to permit everyone to sharpen
scissors to professional standards, simply and easily. The ScissorPro®will put an incredibly sharp
edge on your kitchen, household, sewing and arts and crafts scissors. It is important to completely
read this booklet to optimize your sharpening results.
ScissorPro®owes much of its uniqueness to its precision magnetic guides, designed to hold the
scissors blade securely at a precise angle against the specially contoured, Omni-Curve™rotating
diamond abrasive disks. These guides (see Figures 1 and 2) incorporate a unique hold-down spring
mechanism and, in combination with the magnets, comprise the unique Magne-Flex™scissors hold-
down system. Before sharpening your first scissors it is important to read the following section:

IMPORTANT INFORMATION
1. WARNING: EVEN THOUGH ALL SCISSORS MAY APPEAR TO BE SIMILAR, THERE ARE
MAJOR DIFFERENCES AMONG THEM THAT MUST BE UNDERSTOOD BEFORE YOU USE THIS
SHARPENER. THE ScissorPro®WILL SHARPEN MOST, BUT NOT ALL TYPES OF SCISSORS.
DO NOT ATTEMPT TO SHARPEN HAIR STYLING SCISSORS, PINKING SHEARS, MANICURE
SCISSORS, SERRATED BLADES, TIN SNIPS, SCISSORS GREATER THAN 12” IN LENGTH OR ANY
BLADE THAT DOES NOT FIT READILY IN THE SHARPENING POSITION.
ScissorPro®will sharpen most other blades, including those of knife-edge scissors, as
described later. It is essential that you follow the instructions to optimize your results.
2. Obviously, all scissors have two blades, Not so obvious is that often these blades are very
different. When you cut with scissors, one blade (the anvil blade) is below the material, and the
other blade (the cutter blade) is above the material, as shown in Figure 4.With certain scissors,
the blade on top of the material (the cutter blade) does most of the cutting.
There are several ways to distinguish the cutter and anvil blades. Referring to Figures 3 and
4, note the cutter blade usually has the oblong finger-hold and a more rounded tip. The anvil
blade has a more pointed tip and a round finger hold.
3. It is important to be able to identify the special knife-edge type scissors. They have a cutter
blade factory sharpened at a very low angle to form a knife like edge that is extremely sharp.
THE KNIFE-EDGE BLADE MUST BE SHARPENED ONLY WITH THE KNIFE-EDGE ACCESSORY
SUPPLIED WITH EACH ScissorPro®. With these scissors, the knife-edge cutter blade does
virtually all the cutting. When sharpening this type of scissors, only the knife-edge cutter blade
needs to be sharpened. If you have any doubt about whether you have this type of scissors,
ask your nearest fabric or sewing center to help you identify these special blades before you
sharpen them.

4. During the sharpening process, you will be asked to feel for a burr on the scissors blade
in order to know when sharpening is complete. It is essential that you understand how this
is done.
Feeling for a burr involves running your finger carefully across (NOT ALONG) the back of the
blade as shown in Figure 5. A burr is a microscopic protrusion of metal produced during the
sharpening process under the edges of the blade that can be felt but is not always visible. It
will feel rough and jagged compared to the smooth finish of the back of the blade.
5. Your ScissorPro®will sharpen either right hand or left hand scissors without any need to
disassemble them. If you are left handed, you probably have purchased left hand scissors.
To sharpen right hand scissors, turn the sharpener so you face the switch side of the
ScissorPro®(see Figure 6). To sharpen left hand scissors, you should face the opposite side
of the sharpener (see Figure 7). From this point onward, these instructions are written as they
apply to right hand scissors.
6. Before you turn on your ScissorPro®,take a minute to get the feel of the Magne-Flex™
hold-down system and to learn how to insert a blade into the sharpener. Select a blade and
insert it—cutting edge first—under the fingers of the hold-down spring of the FINE sharpening
slot using the grip shown in Figure 6. If inserted correctly, the blade being sharpened is the top
blade, and the free blade will be hanging below the blade being sharpened.
Practice inserting the scissors blade under the hold-down spring, as close to the scissors
pivot as feels comfortable and pulling the blade smoothly toward you. Feel the effect of the
magnet and hold-down spring as they establish the sharpening angle for you. Light pressure
is required to slide the blade down the magnet slope and underneath the hold-down spring
as the blade approaches the diamond sharpening disk. Allow the Magne-Flex™hold-down
system to control the sharpening angle for you. It is also important to prevent the free blade
(that is the one not being sharpened) from hitting the sharpener in a way that might influence
the sharpening angle. It is convenient to stabilize the free blade using your forefinger and
thumb as shown in Figure 6. Turn over the scissors and repeat with the other blade.
7. Generally, most scissors can be sharpened by using only the FINE stage (Figure 1). The highly
efficient diamond abrasive used in the ScissorPro®will quickly develop a superbly sharp edge.
The COARSE stage sharpens at a larger angle using somewhat large diamonds.

SHARPENING PROCEDURES
GENERAL PROCEDURE
Read this before starting to sharpen.
Either blade may be sharpened first. You will find when sharpening correctly that the blade you
are sharpening always ends up to be the top blade. The free blade always hangs freely below the
blade being sharpened. In any sharpening stage you should lay the back of the blade on the magnet
surface as close to the pivot of the scissors as feels comfortable. Then, slide the scissors blade—
cutting edge first—under the hold-down spring using slight thumb pressure as shown in Figure 8.
Make sure that you allow the hold-down mechanism to control the sharpening angle for you.
Continue moving the scissors blade into the hold-down slot until gentle contact is made with the
rotating diamond disk. Upon contact, you should pull the scissors promptly but slowly and evenly
toward you, keeping the blade in contact with the diamond disk all the way to the tip of the blade.
Each sharpening stroke should take 1-2 seconds for a 6” scissors. Longer scissors require more
time; for example, 3-4 seconds for a 10” scissors. It is convenient to complete all sharpening steps
on one blade before beginning to sharpen the second. Proceed as follows:
FOR STANDARD SCISSORS
(Note: for knife-edge scissors blades use only the special procedure on page 7).
Press switch to “ON”.
Step 1—Fine Stage
Always start with the FINE stage. Use the General Procedure outlined above; select one blade and
pull it through that slot three (3) times.
a. If a uniform burr is felt (see item 4, page 4) along the entire back of the blade, give the blade
one (1) faster pull (1 second per pass) to reduce the size of the burr. Proceed to Cleaning step
below. You are now finished with this blade and you can start sharpening the next blade.
b. If no burr is felt proceed to Step 2 below.
Step 2—Coarse Stage
Following the General Procedure, pull the blade through the COARSE stage (Figure 9) 4-5 times and
check for a burr. With some blades it may take 10-15 strokes to develop a burr along the entire
blade length. When a burr has developed, give one last fast pull (1 second) and then repeat Step
1 in the FINE stage.
CLEANING
After each blade is sharpened, clean the blade with a soft cloth of folded paper towel. CAUTION:
the blade and burrs are now very sharp. Then slowly close the scissors, which will cut off the burr.
Then clean off with the cloth any burr fragments that may remain.

FOR KNIFE-EDGE SCISSORS
Knife-edge scissors, designed particularly for cutting heavy fabric layers, have one or both blades
capable of cutting like a knife. Commonly, only the cutter blade of this type scissors has the knife
edge. When that is the case, and you can properly identify and sharpen that blade, sharpening the
other (anvil) blade is optional or even unnecessary. Only the knife-edge scissors blade is sharpened
by this special procedure. If you elect to sharpen the anvil blade, use the standard sharpening
procedure described above. Do not confuse these blades.
Proceed as follows:
a. Insert the Knife-Edge Scissors Accessory to the FINE Stage.
b. Press switch to “ON”.
c. Using the general procedure, pull the blade through the slot two (2) times.
- If a burr is felt along the entire back of the blade, sharpening is complete. Then clean the
scissors as described above.
- If no burr exists, make 2-3 additional stroke. If a burr still has not developed, then this is not
a knife-edge blade.
d. Remove the Knife-Edge Scissors Accessory and proceed to sharpen this blade as with
standard scissors.
e. Never store the ScissorPro®with the Knife-Edge Scissors Accessory positioned in the
Magne-Flex™guide. Always remove and store the accessory in a safe place when not in use.
SUGGESTIONS
Your ScissorPro®Diamond Hone®Scissors Sharpener Model 500 is designed to produce scissor
edges that are like new, quickly and easily. To ensure you get the very best scissor edges every
time, we suggest:
1. Loosen your grip on the scissors and use your thumb to advance the blade gently against the
rotating disk. Never apply excessive pressure when the blade is against the diamond disk.
2. Make sure the loose blade does not interfere with alignment of the blade being sharpened.
3. Pull the blade through the sharpening slots with an even and continuous motion. Do not stop
the motion. Be sure to make fast pulls after sharpening in each stage. This minimizes the burr.
4. On each stroke, start at the pivot and pull the scissors handle as necessary to maintain the blade
in contact with the diamond disk as the curved section of the blade is pulled through the slot.
5. It is essential to learn how to feel for the burr. This is the best indication sharpening in a given
stage is complete. Make certain the burr has formed along the entire blade… from pivot to tip.

Figure 9. Coarse Stage.Figure 8. Start with the “Fine” Honing Stage.

6. With poultry shears, you need to sharpe only the smooth convex blade. The concave (usually
serrated) blade will not need sharpening.
7. Do not attempt to sharpen serrated blades. However, where only one blade is serrated, the
other can be sharpened using the procedure for standard scissors. Look carefully for serra-
tions. They can be very small and difficult to see.
8. Scissors Adjustment: All “professional” scissors and many other scissors have a screw ten-
sioner at the pivot. The performance of your scissors and your scissors life may be improved
by adjusting this pivot to establish and maintain a smooth edge contact when you close the
scissors. Proper adjustment is determined by opening scissors to 50% of blade length, then
tightening until blade looseness is just barely removed. It is important that the pivot not be
overtightened. (If you are uncomfortable with this adjustment—seek assistance.)
NORMAL MAINTENANCE OF THE ScissorPro®
No lubrication is required for any moving parts, motor bearing surfaces or sharpening surfaces.
Your sharpener may be cleaned by carefully wiping with a damp cloth. Do not use detergents
or abrasives.
To clean metal dust that may accumulate in the sharpening section, simply remove the circular
plastic plug that is located on the underneath side of the sharpener. Shake out the metal dust and
replace plug. Do this once every eighteen months for normal use or more often with heavy use.
SERVICE
In the event post-warranty service is needed, return your sharpener to the EdgeCraft factory where
the cost of repair can be estimated before the repair is undertaken.
Please include your return address, daytime telephone number and a brief description of the prob-
lem or damage to the sharpener on a separate sheet inside the box. Retain a shipping receipt as
protection against loss in shipment.
