Inspect your sharpening machine for shipping damage. Look for broken or bent parts. Notify freight carrier if damaged. Assemble plastic eye shields. Attach to the Twice as Sharp® with screws provided with your equipment. Never operate your scissor sharpener without eye shields in place.
The question of maintenance comes up from time to time concerning the Twice as Sharp® scissor sharpener. Here are a few things you need to know:
Routine Maintenance
Never oil any part of your scissor sharpening machine. The motor bearings are sealed ball bearings. The arm bearings are self lubricating and need no lubrication. Just be sure to brush or blow off grit as necessary.
The Sharpening Clamp
If the clamp movement becomes stiff or difficult, loosen the angle knob and clean any grit out.
To sharpen, slide blade across the LEFT wheel slowly with a light pressure against the wheel. Keep arms in the position shown and slide blade from pivot to tip. If machine slows down, use less pressure.
The following angles are used on most scissors today and produce the greatest customer satisfaction. Sharpening old scissors with the new angles produces the desired cutting ability. Scissors that have been previously resharpened were often done at the wrong angle.
Your scissors are now sharp. Close them several times normally, wipe clean, and test as follows:
Pinkers, embroidery: 1 to 2 layers, 8 to 11 oz. double knit
Kitchen Shears: 3 to 4 layers, 8 to 11 oz. double knit
Fabric Scissors: 6 or more layers, 8 to 11 oz. double knit
Knife Edge Shears: 2 to 24 layers, 8 to 11 oz. double knit
Paper Scissors: test on 2 layers of newspaper
Barber Shears: 1 layer paper towel, hair if available
Thinning shears: 1 layer of 20 lb copy paper or paper towel
Surgical shears: 1 layer of latex rubber
To start, loosen the small black knob on the side of the clamp and move the clamp’s upright to the desired angle. The angle is determined by the break line (space) between the upper and lower sections of the clamp. (NOTE: Sharpen all scissors with the same angle setting before resetting the angle to save time. Small variations in angles won’t noticeably affect cutting.)
