Whats your time worth? And where do you get a blade for $0.02, even Amazon doesn't list them for that price. 10 pack for $7.99, or 81 for $18 not including shippnig. Hell I've been using the same blade for over 6 years, and sharpen it 2 or 4 times every time I start cutting up boxes. Believe me sharpening the blade is a hell of a lot cheaper.
