The Kinkajou Bottle Cutter

  

Recycling glass bottles is something we should all be doing but cutting them and reusing them is more fun. The Kinkajou is a crafty bottle-cutting tool that lets you turn your empty wine and beer bottles into drinking glasses and vases. The Kinkajou is currently AVAILABLE at http://www.thekinkajou.com/

About the Kinkajou

Named after the small South American mammal with big teeth the Kinkajou is a bottle cutter with a new twist. The cutters currently available on the market are big and bulky and not very interesting to look at. My design was meant to be simple to operate, easy to store and more aesthetically pleasing; something you wouldn’t mind keeping in your kitchen.

Some of my favorites:

The evolution to the Kinkajou:

Cutting a bottle is an easy 3-step process

Actually it’s a 4 step process if you include consuming the bottles contents first 🙂

  • Scoring: While the Kinkajou is called a bottle cutter it does not actually cut the bottle. The tool is meant to create a score line on the bottle at the location you wish to cut the bottle. You simply need to put the Kinkajou around the bottle, tighten it to create a snug fit and align the cutting wheel to the location you want to score the bottle. Once it is snug and the cutting wheel is at the proper location, start slowly turning the bottle. You only want to go around once.
  • Separation: There are many videos on the internet showing different methods to separate the two sections of the bottle but after trying them all, the method that produces the most consistent results is simply to use hot water (doing this over a kitchen sink is recommended). Boil some water and pour it over the score line. After a few seconds, use a faucet to pour cold water over the same score line. This cycle of hot and cold will cause the bottle to crack along the score line. The bottle should separate after one or 2 cycles of hot and cold, thicker glass may take additional cycles.
  • Finishing: Now that you have separated the two halves you will be left with a sharp edge. To remove this edge, you simply have to sand it down with a piece of sand paper. The sand paper needs to be made of silicon carbide or aluminum oxide (I will include the proper sandpaper with every Kinkajou I ship). Using water to keep the sandpaper wet will help keep the dust to a minimum. There are 3 sections to sand: the outside edge, the inside edge and the flat surface. Using an 80 grit sandpaper to start, will quickly remove the sharp edge but will leave the glass scratched and frosted. If you want to bring this edge back to a smooth clear like finish you will need to use multiple sheets of sandpaper with a different grit. These are the grit levels I would recommend. 80, 120,180,220. Once you’ve sanded the glass with a 220 it should be very smooth, if you want to make even smoother you will need to use glass polishing compounds (found at your local hardware store).

Color Voting Option

While the Kinkajou will be available in 2 standard colors, bright white and deep black, there will be a third color. This color will be decided via a majority vote by all those who have backed the color voting option. If any of these backers are unhappy with the winning color they will be allowed to select one of the two standard colors in its place.

Design Changes

1. To ensure that no additional tools are needed to operate the Kinkajou, the securing mechanism has been redesigned. It now includes two small handles to lock in the bottle once it has been hand tightened.

2. The cutting wheel has also been redesigned to be spring-loaded to ensure the correct amount of pressure is applied to the bottle at all times.

How will the money raised be used?

The Kinkajou will be manufactured using a process called rapid injection molding. This process requires me to first create a master mold.

I need a large enough initial order to take advantage of the economies of scale. My initial order needs to be in the thousands in order to bring the per unit price down enough to make this product affordable. Every Kinkajou will be made up of approximately 35 separate parts.

The majority of my rewards include shipping. I did this to simplify things but my actual cost to ship Kinkajou’s across North America is substantial. Approximately 25% to 30% of a typical $50 pledge will be used for shipping.
