Common Questions About the LionSteel Q4ttro

The LionSteel Q4ttro builds on the modular heritage of the T.R.E. series, offering a sophisticated EDC folder with four distinct opening methods. Crafted in Maniago, Italy, this series features premium CPM-MagnaCut steel and a robust titanium frame lock.

What kind of steel does the LionSteel Q4ttro use?
Every model in the LionSteel Q4ttro series features a CPM-MagnaCut steel blade with a satin finish. MagnaCut steel is highly regarded for its exceptional balance of toughness, edge retention, and corrosion resistance.
How many ways can you open the Q4ttro?
The Q4ttro offers four distinct opening methods: a removable back flipper, a front flipper, a blade cutout for thumb or reverse flicks, and a traditional two-handed opening. This versatility is made possible by the ReF (Removable Flipper) system and smooth ceramic ball bearings for effortless deployment.
What handle materials are available for this series?
The Q4ttro series utilizes a titanium frame lock construction paired with several inlay and scale options. Depending on the variant, handle materials include black G10, green burlap Micarta, carbon fiber, or marbled FatCarbon in various colors.
Is the LionSteel Q4ttro a good size for everyday carry?
With a 3.3-inch blade and a full-flat grind, the Q4ttro is optimized for daily cutting tasks and provides enough handle space for a comfortable four-finger grip. The milled titanium pocket clip and relatively slim profile make it a capable and pocket-friendly choice for EDC.
Does the Q4ttro come with maintenance tools?
Yes, LionSteel includes a set of dedicated adjustment tools with the Q4ttro, including T6 and T8 bits. These tools allow you to easily adjust the pivot or remove the flipper tab according to your preference.
Why is the LionSteel Q4ttro popular with collectors?
The Q4ttro stands out because it combines the modularity of the award-winning T.R.E. system with modern MagnaCut steel and high-end Italian precision. Its ability to change deployment styles while maintaining a clean, technical aesthetic makes it a unique and versatile addition to any collection.
