I have to say that my new Tri Cu Neutral is my favorite Mac EDC to date. I have had the pleasure of owning a few of Mac's EDC's so my opinion counts. The Cu is definetly a keeper. Perfect tint, beam profile and H/M/L mode output separation to suit my needs. The character of the copper patina will develope with time and use making this a worry free EDC as far as finish goes. No parinoia of nerfing a Ti finish or the concerns that come with Cerakote chipping, scratching or wear through.
Just a totally bitchin handmade work of art that you can carry everyday for the rest of your life and leave to a worthy heir.
