This is by far my favorite piece of titanium and I have a lot of titanium edc stuff! I now own the 30mm, 42.7(golf ball) and the 50mm! Love them all, now just waiting for the 100mm to restock! They all have there own different noise when being bounced. It is obviously very tough being titanium but the lattice design I believe makes it that much more tougher. It looks amazing, it’s like a piece of art! I love looking at it, holding it, rolling it around and of course bouncing it! Also like pulling it out just to show it off to other people because i know they have never seen anything like it and most are fascinated like myself. Great customer service! Customer for life here and look forward to other cool things y'all come out with! Don’t know if possible but could y'all make like a double thickness like y'all did with the 100mm for the 42.7? Thanks for the great product guys, and keep up the good work!
