This range of Faithfull Flexi Blades are designed for use in conjunction with the FAIPFLEXMAS Flexi Master Trowel. They are the only metal interchangeable blades available that are supplied moulded to a unique 10mm foam backing. This drastically increases the blades flexibility when in use compared to a fixed handle flexible trowel. Simply select your blade and insert the Flexi Master Trowel into the Flexifit system and start plastering. Each blade is lightweight, easy to use and designed with squared and rounded corners on opposite edges of the blade, giving you the option to use the system in a variety of ways. These steel blades are supplied with a full blade guard which should be removed prior to use, and we recommend reapplying the guard to protect the blade when not in use.
