I picked up a Kershaw launch 4 recently because they look cool, and I'm a Kershaw fan. I was a little surprised at how small it is, especially in my big hand. After playing around with it and trying not to puncture myself for a few minutes, I noticed how difficult it was to mash the release. The button is very small and it kept sticking. I oiled it and it seems better, but not where i want to be. Anyone have one? I'm hoping over time it will loosen up.
