OPERATION TIPS
SHARPENING SCISSORS
If possible, take the scissors apart to make the sharpening operation easier and safer. Remove
material only from the outside surface and work from the heavy end of the blade towards the tip.
SHARPENING SCREW DRIVERS
The end of a properly sharpened screwdriver will be a perfect rectangle, absolutely flat and
perpendicular to the center line of the shank. The two sides and two faces will taper outward from
the edge of the shank of the screwdriver. They should be flat with intersecting faces perpendicular.
Hold each face of the screwdriver against the wheel to true it up, and then ease the end straight
into the stone to grind it true.
SHARPENING KNIVES
Remove metal from both faces of most knives, working from the heavy end of the blade towards
the tip.
SHARPENING TWIST DRILL BITS
Drill bits are best sharpened on a sharpening jig but some sharpening can be done on your bench
grinder. Begin on one side of the point at the existing angle, then twist the bit while maintaining
a constant angle with the grinding surface. Sharpen only the tip. This technique requires
considerable practice so try a few times with the grinder OFF. Be sure to maintain the original
cutting edge angle, as this is important to maintaining the efficiency of your bits.
