Been wanting one for a while and finally got one of these in good condition, a Boker Superliner (not my photo). Several versions were produced in the late 90s and early 00s, but the late 90s model number 2063 with the 2000 in the titanium handles is the best of the bunch imo.
Just a really cool piece. representative of the style of customs from the time, (i believe this is a Michael Walker design actually), and also very fitting with the Y2K esthetic of the period.
Lockup and action are good (teflon washers are overhated if you ask me), ergonomics are ok but clearly take a backseat to style.
