These torque wrenches are the ideal for tightening and loosening the screws on all of our Zuani/TWT cutting tools. They are designed not to strip or apply excess pressure, and will shut off the torque delivered to the screw with a characteristic click when the right tightness has been reached. Take the guesswork out of knife changes and save yourself the time, money, and potential safety hazards stripped or improperly tightened screws on your tools can mean by using the right tool for the job.
