"I'm sure it's at least drawn blood in accident.
"
Heck, it's drawn my blood. I very carefully sharpened it to about as good an edge as is possible. I've cut myself a couple of times.
Anyone who has not cut himself (minor) sharpening a knife is: compulsively cautious, or; doesn't own many knives, or: most commonly, carries about a dull knife, the most dangerous kind to use. A half-dull knife makes its owner try too hard and when it finally slices through its bit of work, there is the tip of one of your off-hand digits just waiting to get sliced off.
