I wanted to get some photos up of the new captured bearing race on the Triple Aught Design Dauntless MK4. Apologies ahead of time for the cell phone pics.
The lockface on the MK4 and MK3 appear to heat treated or carbidized? The bearings are captive in a small metal race, which makes me think Kershaw / KAI is not producing the Dauntless. The race is stamped around the bearings and appears very solid but does have an open "back" which could possibly lead to some lint or dust choking unlike KAI's solid poly races.
On the G10 side, the bearing race rides on a metal spacer to keep the bearings from wearing the G10.
The grinds and sharpening are beautiful. The stonewashing is less aggressive than the MK3 but still much nicer than the previous blasted finish.
All told, a great improvement on the production Dauntless'. I will use this knife exclusively through the winter and report back on the bearing system and lock movement.
