神奇刀让黄油一触即化 A new knife is hoping to solve the age-old problem of spreading butter straight from the fridge. The SpreadTHAT! blade uses a heat-transfer system that captures a user’s body heat to melt through hard butter. The advanced technology means that the device requires no batteries, charging or power of any sort. Its designers developed the device using a copper alloy* tube which instantly transfers heat from the palm of a hand to the end of the blade. It’s similar to that used to cool down computer processors* in the semiconductor* manufacturing* industry. The device has proved a success on crowd-funding* website Kickstarter, surpassing its US$20,000 target within days. Writing on their Kickstarter page, the company said: “We wanted to create a spreader that can effectively spread cold butter, and we wanted to do it without using any electricity nor hot water. We also demanded a solution that is completely safe to handle by small children, meaning that there cannot be any sharp edges.” The team behind the device, based in Seattle, Washington, the United States, hopes to have the product in mass production in time for Christmas. It is expected to retail at around US$25.(SD-Agencies) |
