LINDER Black Tactical Double Action= (Works Automatically or Manually) Hidden Button Release Liner Lock Auto with 440 Stainless Blackwash Blade

This model works manually via the dual thumb studs or automatically via the hidden release located under the textured hard rubber inlays.

Lone Wolf had a model somewhat similar in operation, but much larger (the D2 Harsey), which is highly collectible today, in fact, nearly all the hidden button models are now extremely collectible.

There are very few "high quality" double action models out there with the hidden button  mechanism.This model has a Zytel frame with stainless liners and non-slip textured hard rubberized  inlays on both sides. Black stainless pocket clip on the backside.

Opens Manually with one hand with silky smooth action via the dual thumb studs. Also Opens automatically via the hidden button located under the rubber inlay on the front side. Totally hidden release. If you need a discreet auto, this is your choice.

No one will ever figure out this is an auto unless you tell them. Don't let the low price fool you. This is a very nice piece, and if released under a more prominent brand name like Benchmade or Protech would easily sell for $100-$200 more. Switchblade action is positive and fast. Lockup is excellent. (Watch the video on how to open this knife)

Special Black Tac Model measures 4 1/2" closed. 3 1/4" "Blackwash Finished" (like a stonewash finish but blackened), blade has dual thumb studs and features 440C Stainless. Blade is marked "LINDER 440 ROSTFREI"  Leaf Spring operation. One of the most affordable double actions on the market. Totally discreet auto operation.  Highly Recommended.
