glad you agree sir!grinders are nice but i dont need them anymore.rathers feel it between my fingers when rolling a joint.i dont know.maybe im getting old.i dont use vapes so i dont need them.I used to have one of the Ti Space Cases and it was great. Only issue was keeping the screw thread clean. Hard to comment on the alloy used and % of titanium...
Nowadays I use the Storz & Bickel orange plastic thing like you. Or more often than not just my fingers.
