The Techflex Hot Knife Accessory Kit provides everything you need to organize the cord, plus tighten and clean the blade. The replacement blade attachment screws are reliable socket head bolts than can be easily tightened with the provided allen wrench for the best possible contact with the heating element. Use the wire brush to clean buildup from the blade periodically. The included Velcro One-Wrap strap lets you bundle the power cord for easy storage and transport.
