Revision as of 13:56, 9 February 2014 by en>Slawekb (Restored last good version of the article. The new revision is unnecessarily long-winded, and uses the Heine-Borel theorem in the proof (!) which introduces a circularity in the argument of that theorem. Will add "Theorem 1" as an easy corollary.)

Scales or grips are usually attached to the manage portion for a more comfy grip.
