A brand new, unsharpened standard pencil — the classic No. 2 yellow pencil from Dixon Ticonderoga, Staedtler, and Faber-Castell sold at every Staples, Walmart, and school supply store across America — measures exactly 7.5 inches fresh out of the box. A pencil sharpened a few times lands right at the 7-inch mark.

A standard butter knife — the everyday flatware piece from dining sets sold by Oneida, Reed & Barton, and Pottery Barn at Crate & Barrel, Williams Sonoma, and department stores across America — measures approximately 6.75 to 7.25 inches in total length.
