My dad retired as a conductor on the Rock Island. That's his lantern, it's probably gone a million miles. I got hired as a laborer on the Rock when I turned 18. Hard work, great money. Got laid off and went back to the truck stop until joining the US Air Force, pic has my union military withdrawal card. The Rock Island was no longer a mighty fine line, it went bankrupt while I was on my first hitch. My background automatically drew me to the 33. I have OCD about blade rub, and most factory knives that open at opposite ends on a single spring generally can be expected to have some. Conductors are no exception. The 33 is a true slipjoint, no halfstops, it opens smoothly and doesn't try to bite you. Sharp tip works great for my uses. I don't have a 34 to compare but I prefer smaller traditional folders and can't see any advantage it's extra size and weight has over a 33. I do wish all 33s had coping secondaries.
