The KA-BAR TDI Flipper Folder 2490 is a tough and practical EDC pocket knife, designed by John Benner. When in doubt go with black. This is true for your outfit, but also for your KA-BAR pocket knife. You open the TDI Flipper Folder with the flipper. You can also use the thumb studs, even though they serve more as a stop-pin.
The handle and the blade are black. G10 and stainless steel for the handle, AUS8A stainless steel for the blade. When opened the blade is blocked by a solid framelock. The great thing about this pocket knife is that the profile is nice and slim even though it has a 9 cm blade. Practical!
