SPF....................... Behold the rare and highly collectable Parker Imai model K-534, considered by most balisong enthusiasts to be the BEST of the 1980s vintage Seki City imports. This beauty is LNIB with no handling marks and NO PATINA on the brass handles. Factory edge was dull, so it was sent off to member WickedSharp to have a mirrored edge done. This will slice a roll of paper towels down to the cardboard tube now. The Parker Imai K-534 with the 4" blade is so desirable due both to the unique deep bellied blade profile, as well as the grooved and recessed brass handles. You are unlikely to drop this knife, VERY grippy handles. Flips like a dream, tight lockup both open and closed, you will not be disappointed with this top quality balisong. I recently paid 170 for this. It is a steal at $80 shipped, priority mail, insurance, and PayPal fees included. No trades unless you have an interesting Spyderco hawkbill that is lefty friendly.
