The Kwaiback MK5, introduced in June, 2019, incorporates some new design changes that both improve performance and allow for longer periods between cleanings!
The MK5 has:
- An external stop pin versus an internal stop pin
- A detent that engages the blade at the stop pin track versus its own hole in the blade
- An improved lock insert shape and a reduced number of hold-down screws
- Improved lightening pockets for easier cleaning of the knife
