The Abbey Bike Works Chain Whip is the perfect complement to the Dual Sided Crombie tool -- in fact, the Crombie stores neatly inside the Chain Whip's handle. It uses a single length of chain to simplify the design and eliminate a weak spot of traditional whips. Also differentiating the Abbey Bike Works Chain Whip is the 12in stainless steel handle that offers plenty of leverage, and a comfortable grip.
