Roadie.
Born of a rather convoluted pathway- where the FAA had suggested EASA would be allowing a very specific type of folding knife back onto planes, Spyderco leaped in with their compliant design in anticipation.
However, it turned out this wasn't the case and the Roadie was born.
(Aside- this kind of duff info is typical of the FAA's field offices from my day-to-day experience in the aerospace industry. I can say for a certainty EASA weren't even considering it, being even more risk-averse than the FAA)
What we are left with is- in fact- an excellent little knife and what I consider to be the Spyderco 'modernized finger-nick slippie' of olden days of yore
It's nearly impossible to open one handed just using your thumb- as required by the original spec.
You can grip the machined divot (Which is the original precursor of the Spyderhole) and hook the back of the handle against a clothing seam to lever it open if needs be.
Slipjoint is at a 'goldilocks' setting- neither too stiff nor too weak but just right.
N690 holds an edge nicely and the choil is well shaped to keep you safe in use. There's just enough curve to the blade to make it more versatile than the straight-up sheepsfoot or whancliffe.
This has turned out to be one of 'those' knives that everyone- even non-knife-folks- really like...My father in law had to be patted down at a family gathering to get it back after saying "Aww. That's a handy little blade. Oi loike that"
This one is extra special to me as it was part of my first Amsterdam Meet goodie bag...I added a Spydie lanyard with some extra GITD paint in bugs to give my littlest finger something to rest upon.

Warhammer 40000 is- basically- Lord Of The Rings on a cocktail of every drug known to man and genuine lunar dust, stuck in a blender with Alien, Mechwarrior, Dune, Starship Troopers, Fahrenheit 451 and Star Wars, bathed in blood, turned up to eleventy billion, set on fire, and catapulted off into space screaming "WAAAGH!" and waving a chainsaw sword- without the happy ending.
