Got my DFLE in the mail today (and also an Optimus 111 stove I got off eBay). Double delight.

What can I say. It's awesome. What's most striking is how much nicer a full flat ground knife feels in the hand than a saber ground knife. I also have a Swamp Rat Battle Guard (they're also full flat grinds) that feels so much better than a regular Battle Rat.
