NOS Recently uncovered from a Florida hoard! These are functional but meant for the collection not use. These are clean but they do have some level of oxidization inside and will stick and misfire on occasion but mostly are just awesome relics with an entirely different internal system for effecting what we see today in widespread use for a dual action OTF we found out when we cracked one open. Do not oil this knife at all. Only use graphite for lube. If you get curious and hammer this knife open you will find a mechanism no one ever even considered for DA OTF it's quite amazing. Plastic green handles with a top slider as shown. Push the slider to open pull back to retract. One per customer max please.
