I just got my first serious (ie: non-kitchen-use) knife, a Delica 4, but think it needs some lubrication to help it open more easily.
I've read through several lubrication threads already and it seems that WD-40 is not preferred as it doesn't leave a lasting grease for continual lubrication. I've ordered some Militec-1 but that won't arrive for a couple weeks. I went to a local gun/knife store, and they sell Tetra and Ballistol. I asked which would be better for knives, and they all said Ballistol. Does anyone have any experience with this? It has a strange odor (reminds me of that fish attractor stuff you spray on lures), and seems to be almost identical to WD-40, but may have more mineral oil than WD-40 (which only has ~15%). However, I couldn't find any specifics about what is actually in it.
However, after using Ballistol, there still seems to be difficulty opening the knife, especially right before its about to click fully open. If I hold the blade with my thumb and index finger and slowly open it, I can feel the higher friction at certain spots. Any suggestions? Would plain old mineral oil work alright?
