I've heard Tony Bose puts pivot bushings inside his custom slip joints, so I know it's not unheard of to do such a thing. I know almost nothing about slipjoints, but it seems like it might be a bad idea to have a non-bushing model slipjoint built as a user servicable piece, in the way all CRK folders can be taken apart and reassembled so easily.
It's my assumption that the tightness of the pivot on a slipjoint would have to be set very perfectly each time, more so than a standard locking folder. To keep the slipjoint from disengaging during use if it was too loose of a pivot. But I know almost nothing about slip joints, and I imagine CRK's engineers put significant thought into this endeavor so maybe it's actually preferential to use a non-bushing system on a user servicable slip joint for some reason? Curious to learn more about it, for sure, from an engineering perspective at least!
