Patented, oil-resistant, anti-slip, plastic flock on handle helps prevent slippage. Rounded end virtually eliminates pressure points in the palm of the hand. Triangular-shaped handle for more turning power. Handle size and shape provide greater contact area with hand for maximum turning power and a more comfortable grip.
