Another :thumbup: on getting your CF Hati, Thin-Slice. Nice one, man. As much as I like my BB Shiros, I'm really enjoying the feel of the Hati on washers now that I've got mine tuned up--feels like a CRK flipper with sort of that same hydraulic smoothness. I still might take another taste off the washers, though.
I like your funky tool, too. I keep a quarter, nickel, and penny in with my knife tools and use whichever one fits a particular PacMan screw best.
And Scrim's right--reassembling AXIS lock knives is a PIA. I too have found that slipping the blade and washers out the front without disassembly after pulling the pivot is the best method. When reassembling, I slip the D-shaped pivot in first just a little proud of the first liner and drop the first washer on that. Pull back on the AXIS, slip the blade in, and push the pivot up into it. Then you can let go of the AXIS, feed the last washer in, center it with a tooth pick or similar, and push the pivot the rest of the way through. Seb 21s and other bushing pivot knives (like the Hati) make this process super easy.
