By now, a lot of people credit Microsoft co-founder Bill Gates. As the saying goes, the best person for the job is a lazy person, because he’ll find the easiest way to do it.

Now I’m not saying the founder of Experimental Fun is lazy, but he does come up with interesting ways to reduce the amount of work he has to do in the future.

Take for example this customized kitchen knife, which is made to hold three utility blades on its cutting edge. By swapping out the cheap blades once they get dull, you never have to sharpen the knife itself.

Let’s take a look at Experimental Fun’s custom knife, shall we?

Making The Blade

The main attraction of the knife is the blade shape that is drawn onto a piece of metal before being cut out.

Once the metal is cut, three indents are carved into the cutting edge using a drill bit. These indents will keep the utility blades safe and snug while you slice away using the handle.

Threading the Screws

To keep the utility blades from falling off, you’d want to add some connectors. After drilling two small holes per utility knife indent, Experimental Fun uses a tap wrench to create the screw threads. These will allow you to remove the blades once they become dull and replace them with fresh ones.

The Handle

You can only do so much with a handleless knife, so make sure to cut and carve out a wooden piece to fit around the tang of the blade. Using a variety of saws, drill bits, and even the exact same utility knives at the end of the knife he’s making, Experimental Fun makes himself a handle fit for a knife-wielding expert.

While most knives use rivets to connect the knife blade and the handle, he instead opts to use screws and nuts. By cutting off the excess metal and filing it down, he creates custom-made connectors specific to the knife.

Putting on the Finishing Touches

Both the metal and the wood get a good amount of sanding and polish to make them more presentable. With that finished, the only thing left to do now is fit in the utility knives and cut some stuff up!

Though Experimental Fun made this knife specifically to save time sharpening blades, he has still mentioned that the carbon blades corrode quite easily, requiring them to be swapped out often. It also goes without saying the multiple parts of the knife make it harder to clean than a single blade knife.

This doesn’t change the fact this knife looks downright awesome. Experimental Fun has always wanted to make something like this and hopes to eventually sell these knives to other like-minded lazy knife users.
