They're in the latest crates. These crates will either:
- Drop a Hat
- Drop a Strange Weapon, or
- Drop an Unusual
You can get them for Rocket Launchers, Direct Hits, Pain Trains, Shotguns, Natascha, GRU, Grenade Launcher, Sticky Bomb Launcher, Chargin' Targe and Eyelander. Valve will be adding more weapons to the strange weapon pool in the near future.
The crates are said to drop these strange quality items commonly, they're just new at the moment so they'll be in small quantities.
Oh, and here's a list of ranks for the weapons:
"KillEaterRank0""Strange"
"KillEaterRank1""Unremarkable...
"KillEaterRank2""Scarcely Lethal"
"KillEaterRank3""Mildly Menacing"
"KillEaterRank4""Somewhat Threatening"
"KillEaterRank5""Uncharitable...
"KillEaterRank6""Notably Dangerous"
"KillEaterRank7""Sufficiently Lethal"
"KillEaterRank8""Truly Feared"
"KillEaterRank9""Spectacularly Lethal"
"KillEaterRank10""Gore-Spatte...
"KillEaterRank11""Wicked Nasty"
"KillEaterRank12""Positively Inhumane"
"KillEaterRank13""Totally Ordinary"
"KillEaterRank14""Face-Meltin...
"KillEaterRank15""Rage-Induci...
"KillEaterRank16""Server-Clea...
"KillEaterRank17""Epic"
"KillEaterRank18""Legendary"
"KillEaterRank19""Australian"
"KillEaterRank20""Hale's Own"
Can't seem to find a kills for each rank at the moment, although I'm sure the wiki will be able to inform us sometime soon.
