Sharp as a Razor
Sharp as a razor means very sharp.
Razors work best when sharp. However, people must shave carefully. If not, they cut skin as well as hair.
Axes and kitchen knives should also be sharp. Like the person shaving, wood cutters and cooks must cut carefully or suffer the results.
Easy does it makes sense around sharp objects. Better safe than sorry.
People sharp as a razor are very smart.
This expression means the same as sharp as a tack. Sharp people:
- Learn easily
- Remember well
Smart people choose whether to use their knowledge.
Some smart people apply their knowledge. Others waste their skills.
- Sharp razors do no good if never used.
- Sharp people do no good if they never use what they know.
People sharp as a razor use their knowledge for good or evil.
Like sharp razors, axes, or knives, sharp people either help or harm. They do well to stay sharp. They do better to put their sharpness to good use.
“A dull ax requires great strength; be wise and sharpen the blade” (Ecclesiastes 10:10 TLB).
