Joseph Fourier's Pocket Knife

A pocket knife owned by French mathematician and physicist Joseph Fouirer. Using the knife, the blade will increase in temperature, resulting in the object melting. The only downside is that using the knife too long will burn the user's hand. Not using the knife for a few minutes will cool it.

Origin
Jean Baptiste Joseph Fourier (21 March 1768 – 16 May 1830) was a French mathematician and physicist born in Auxerre and best known for initiating the investigation of Fourier series and their applications to problems of heat transfer and vibrations. The Fourier transform and Fourier's Law are also named in his honour. Fourier is also generally credited with the discovery of the greenhouse effect.

Origin
The blade was collected by an agent of Warehouse 12 soon after Fourier's death in 1830. The blade has been used many times by agents, but only for a few minutes.
