toe knife

a culinary knife used by Frank Reynolds (played by Danny DeVito) of cult hit sit-com It's Always Sunny in Philadelphia to scrape foul matter from beneath his toenails, causing other characters to comment on their disgust. The knife is probably riddled with disease. Frank uses the knife for other things such as eating.

"Heyo Frank what you doin'?"
"Just usin' my toe knife to cut this bread"

"That's disgusting Frank"

take a knife

If a fool takes a knife he stabs enemies in the back. A wise man will cut himself free before he wants to stab others in the back!

Take a knife, now cut yourself free!

gentleman's knife

A knife that is appropriate to carry with business attire in an urban environment. It's functional and classy without being tactical looking (i.e., without unnecessary, menacing, mall ninja-type features).

Every man should have a classy watch and a reliable gentleman's knife.
