The Flytanium titanium thumbstud kit fits the Flytanim Arcade along with a plethora of Benchmade knives! It's a great way to add a personal touch to your EDC. Our precision milled titanium thumbstud kit has been tested on every knife we could get our hands on and fits most Benchmade models with a two-part thumbstud. It's a perfect replacement for: Bugout, Mini Bugout, Bailout, 940 Series, Griptilian, Mini Griptilian, Mini Crooked River, and Mini Freek. It will also fit even more models, though it is a hair shorter than the stock thumbstud on these: North Fork Folder, Vallation, Mini Vallation, Triage, Adamas, Contego, Mini Barrage, Boost, and Emissary. There are two models it will NOT fit, the Valet and the Nakamura. *Please Note: Benchmade's Warranty does not cover disassembly of any knife by any person other than Benchmade’s Warranty department.
