Curtiss Knives is a custom knife operation based in Indiana, founded by maker David Curtiss. The lineup focuses on titanium framelock flippers built around precision-machined components and a proprietary pivot system designed for consistent, reliable deployment across every unit, with fit and finish that sits squarely between production and full custom.
The F3 is the flagship, and our selection runs it in Medium and Compact sizes with Slicer and Wharncliffe blade options in CPM MagnaCut and S45VN, both covered in our knife steel guide. The handles are where Curtiss shows off: signature milling patterns from diamond to PM and SPM cuts, under anodization work spanning bronze, purple, yellow, gold, and root beer treatments, no two configurations quite alike. That machining detail on handles and hardware is the defining characteristic of the brand, jewelry-grade surface work on a hard-using folding knife.
The wider catalog ranges from compact everyday options like the Dog Tag and Nano flippers up to the full-sized F3 Large, with steels including CTS-XHP and Damasteel depending on configuration, and individually numbered runs like the carbon fiber Cruze landing when the shop releases them. All Curtiss knives are backed by a lifetime warranty from the maker, and the batch-driven output means an in-stock Curtiss is a window, not a shelf: when the run sells through, the next one will be different.
