I also don't advise using bars that aren't knurled.

Double negatives are hard to follow. Don't use no
double negatives, nohow. Avoid double negatives like
the plague, and keep far away from double negatives.
The poster's double use of the negative was not technically a double
negative, and was perfectly correct. He does not recommend - a bar
that is not knurled. Each negative is part of a totally different
segment of the sentance. There is one negative in the verb part and
one in the noun/pronoun part.
