SuStel, I believe you are making your argument for us.  You are clearly explaining <<weq>> as "hitting (something) in the manner in which one hits a drum."  We are arguing that <<chIp>> means "cutting or trimming (something) in the manner in which one cuts or trims hair."

And what is the difference between cutting one's hair and, say, cutting a rope? Cutting a banana? Cutting a presentation? Can you chIp a much?

Sorry, but when Okrand says hair, he means hair. When Okrand says percussion instrument, he means percussion instrument. When you slap your knees rhythmically, your knees ARE a percussion instrument. When you trim the lawn, the lawn is NOT hair. If Okrand had meant "(e.g., hair)" he would have written "(e.g., hair)."

At least until Maltz says otherwise.
