Everyday, women spend about 1.5 hours just to cut vegetables to make curry. Using my $2 prototype, cutting time reduces to just 15 minutes per day!

I live in a rural area outside Bangalore, so I wanted to solve a problem which plagues housewives: Cutting vegetables. Actually, I went to several house and interview housewives regarding the problems they faced in everyday life.

I saw this design being used by a chef just after making my prototype, but it costs a lot: https://www.instructables.com/id/How-to-Replace-th... .

Step 1: Sourcing Materials

I sourced these materials from my junkyard, hence I got it for free! I think this would not cost more that $2 to purchase and make.

Materials:

Knife x8 (I bought one knife for 10 rupees)

Circular plastic container

Circular wood piece

Screw x16

Wood piece

MasherTools:

Cutting machine

Hand drilling machine

Marker pen

Screw driver

Step 2: Mark the Circular Wooden Piece

Take circular wooden piece and mark a square of the required length.

Step 3: To Cut the Circular Wood Piece

To cut the circular wood piece by using the cutting machine as 1 cm less than knife length

Step 4: Place the Knife on the Circular Wooden Piece

Take the circular wooden piece and cut the notches as shown in the image ( I cut around 1 cm ).

Take 4 small wooden pieces and put 2 horizontally and 2 vertically.

Place the end of the knife so that it fits in the notch.

Fix the 4 wooden pieces on the base circular wooden piece by the help of 2 screws per piece.

Fix the screws in the small wooden pieces using a hand-drill or a power drill.

Step 5: Take a Plastic Container

Take a plastic container which has adequate diameter to fit the circular wooden piece tightly and cut the end of the plastic container like half circular.
