Here is a picture of the Chene Tritoon Anchor.
You can see the material added to the flukes (on top of them)
It is a pretty sharp edge design compared to many other anchors. Not enough to cut you, but clearly not soft and rounded design.
It seems to penetrate well and bit hard, but is also easy to retrieve due to the slip ring design.
All I can say is so far so good. Your results may vary,,,
Below is their marketing description:
Chene Anchor Tritoon Boat Anchor
The Chene Anchor Tritoon Boat Anchor features a unique shank configuration unlike any other anchor on the market. This Chene anchor rotates a full 90° degrees, allowing the flukes to penetrate deeply with a full 45° set. This 45° angle provides 4 times more holding power than other slip-ring anchors, and as a result, the Chene Anchor Tritoon Boat Anchor requires 70% less anchor line and performs best with an approximately 2:1 line-to-depth ratio. The unique slip-ring design also allows easy retrieval. The solid steel construction brings more durability, along with a zinc coating that helps protect against the harshest environments, even saltwater. Perfect as temporary mooring for swim rafts, shore moorings, and docks. 15"L x 15"W. Manufacturer's lifetime limited warranty.
