CobraTec Large FS-3 Punisher Black Automatic Knife
CobraTec Large FS-3 Punisher Black is a large-format OTF automatic knife with a D2 steel blade and a high-grade aluminum alloy handle. The FS-3 model uses a dual action mechanism, so both blade deployment and retraction are operated by the same thumb slider.
Detailed product description
CobraTec Large FS-3 Punisher Black belongs to the OTF knife line designed for everyday carry as well as practical use where the user appreciates fast, straightforward operation. The large FS-3 version combines a D2 steel blade with a high-grade aluminum alloy handle, matching the construction approach the manufacturer uses for this model series with a focus on durability and functional simplicity.
The FS-3 line uses a dual action mechanism: the blade both deploys and retracts using the same control slider.
