Unlike many other brands of tools, Channellock tools do not have a lifetime warranty. If your tool experiences any disfigurement or failure, you will be required to pay for the replacement yourself. Additionally, due to the roundness of teeth and the inherent wobble in jointed Channellock tools, they may not cut as smoothly or evenly as other types of tools. Finally, the tips on Channellock tools may become rounded over time, which can reduce the effectiveness of the tool's cutting edges.
