Marking the 10th anniversary of the T.R.E. model, winner of the Overall Knife of the Year award at the 2015 Blade Show, the new EDC folder with multiple opening options is ready: it's time for the Q4TTRO.

This lightweight frame-lock knife features a satin-finished CPM-MagnaCut steel blade equipped with the “ReF” (Removable Flipper) system and ceramic bearings for a smooth and fast action.

The SOLID frame and clip are made of titanium, while the front handle plate is made of G10. The entire handle is designed for a secure and comfortable grip, and the titanium spacer matches the SOLID clip.

Around the pin area there are four manual opening options to choose from: rear opening tab (back flipper), front flipper (front flipper), nail nick (nail nick) or the classic “two-handed” opening.
