I had a similar issue - Neutron didn’t open or close very easily.
After disassembling, oiling, and trying some experiments I determined the liner lock was putting too much pressure ( and therefore friction ) on the side of the blade.
While disassembled, I applied modest pressure to bend it back closer to the liner a very small amount. Now the lockup remains the same, but it opens and closes MUCH more smoothly.
