Ever Wanted a Knife That Spreads Butter AND Toasts Bread? Now You Can Have One Thanks to Colin Furze!

Too many times I have looked in the butter dish while toasting a piece of bread to make a grave discovery……there is no more butter.  I know I will then have to take out a new piece from the refrigerator where it will be so cold that I’ll barely be able to scrape a bit off of it.  Oh, and you can totally forget about getting a nice even spreading of butter on your toast–it will be far too cold for that. I’ve thought, what If I heat up this knife over an open flame, maybe it will cut into the cold butter better then?  But alas, that is a major fire hazard and one slip could torch my kitchen curtains and burn my fingers.  

There has to be a better way! 

What if I told you that there was a knife that you could not only cut and spread cold butter with, but also TOAST the bread as you cut it?  You’d probably tell me “No way, Marisa!  That’s too good to be true, why would anyone buy a toaster if that knife existed?”   Well then prepare to be amazed! I recently stumbled across a YouTube video where inventor Colin Furze has built just that.  Watch the video below to marvel in all of its toasty glory: 

In the video, he explains that the knife is made using a modified microwave transformer that runs a current through cables that are connected to copper tubes that the current passes through and in turn heats up a metal blade attached to them.  This invention looks surprisingly simple to make, and after a few Google searches I’ve found that all the materials can be acquired for less than $100 total. Also, as someone in the comments pointed out, an added bonus is that if you cut your hand with the knife it’ll also cauterize the wound! 

Take a look at his video (and his channel because he has some other wicked cool inventions!) and let me know if you attempt to make a Furzo Toasto of your own!  As for me, I can truly say that this knife is the best thing since sliced bread.
