Thanks to the Lansky Crew for letting me hang on to the Responder Quick Action for a few days. I work in shipping and receiving and need to break down a ton of cardboard during the day. The blade has enough length and weight that it cuts like a hot knife through butter. Three days of work and the edge was still perfectly sharp. The angle of the blade vs the handle left my wrist in a completely neutral position so my wrist felt fine after breaking down 30 or so boxes. I was worried it would be bulky to carry around, but when I clipped it on the inside of my pocket I almost forgot it was there. I can't wait to pick one up in April. Thanks again for the demo guys.

I recieved the responder last week just in time for a hiking trip to the big island of Hawaii. I live on Oahu and I took the responder with me on several hikes into and around the volcano. The knife carried and performed flawlessly.
I have sinced carried the responderfor work (EDC) as a (L.E.O) and again, it carries and performs flawlessly.

Many thanks to Lansky and Willumsen for a great product. Aloha T. Montgomery

Changing the pocket clip on the Responder Quick Action Knife (EDC):

  1. Use the small flathead screwdriver on your Lansky 20-Function Multi-Tool to remove the clip from its original position.
  2. Select desired clip location.
  3. Place a small amount of thread-locking adhesive in the new location.
  4. Position the clip in the new location and adjust the screw until a secure, snug fit is reached.
  5. Set aside. Thread-locking adhesive should set in about 10 minutes and will be fully cured in 24 hours.
