The video discusses an 1889 clinometer, an antique tool used for measuring angles, also known as an inclinometer or tilt meter. The owner acquired it at a flea market and is looking to sell it for $3,500, though willing to accept $1,500. The clinometer is a rare carpenter's tool that provides angle measurements without calculations. It was patented by William B. Melech in 1889, during a time of significant patent activity. The owner believes the tool is valuable, but a potential buyer offers only $150, which is declined. The owner decides to keep the clinometer until a better offer is found.
