GEM Clog Pruf Micromatic came in the other day to complete my "MicroMatic Trio" -- the top cap was a little lazy to open, but after soaking in dawn and water for a day and working it over with mineral oil the TTO spins freely and the top will pop open when the TTO is given a quick spin, but turning the TTO slowly sometimes causes it to hang halfway open, but a quick shake and it pops fully open. It closes tight and locks down and forward, so I'm going to leave well enough alone and it will probably loosen up more with use. Cleaned, polished and once given a barbicide dip, it'll be ready for MicroMatic Monday!
