This is my EDC. It started out life as a standard Spyderco Manix 2 XL. Then I replaced the blade with a custom made recurve with a built-in wave. The lock was upgraded with a silicon nitride ceramic ball and a brass control slider. The scales are now “Jade” G-10. The clip, lanyard tube, and screws are all brass-anodized titanium.
That full flat ground recurve in S90V slices better than anything else I have.
