Tim: Let's talk about knives, these are chef's knives, stainless steel with carbon in them. They're very expensive, so it's a good rule of thumb not to use too much pressure. The pressure must be exact.
Al: Well, what do you know about pressure? You know. I'm almost 40 and I'm still single.
Tim: You keep this up, you'll be 40, single and unemployed.
Tim: As I said, these knives are pricey, and you want to pay attention, Al.
Al: I know what I'm doing.
Tim: I'm just saying, with proper care, these tools can always be a precision cutting instrument.
[Sparks fly as Al puts a knife in the sharpener. When he pulls it out, the blade is half the size it was.]
