What do you think: is your favorite knife the same as the one you use most often, or not? If not, why?
That's a heck of a question.
I'm still getting new knives fairly often and so not carrying the favorites much.
This year it was a few Case Trappers and my first Rat 1 in D2 (my first D2).
I have a few favorites for different reasons. Favorite lock or Favorite lock for winter, the Axis lock (due to taped fingers) which is different from my over all fave lock which is the compression lock.
My favorite knife(knives) is a liner lock invariably so you see where this is going.
Favorite steel doesn't come in my favorite knife.
So no I don't carry my favorite knives much but it is a vacation or feels like coming home when I do.
Some times I need / want to carry my favorite steel (M4) which happens to have my favorite lock so that's a good time.
Some times I carry my favorite (ergonomically / over all) and forgo the top of the list steel and lock. That would be my Ti Lite IV in CTS-XHP full flat ground.
At home today I was carrying and using my latest knife (see how it kicked my favorite out) I needed to cut the end off an old spray tube that goes on my WD-40 Spray can. The tube was clogged up on the end. The tube set in a cup for about a decade. I don't use WD-40 at home much except to clean off goo / as a quick solvent. At home I mostly just use light machine oil for lube (that bottle has it's own thin application tube).
So I used the Case Trapper to cut off the end of the red tube so I could blow the WD into a hard to get at spot.
