The knife is the most used tool in the kitchen.
While it is essential to its use, it is still dangerous in certain circumstances due.
, Certainly on some occasions, the cook must have missed something which could help to use the knife to make certain cuts, especially those that require a certain precision or impaire the dangers of using it.
This is why we developed a design for a holder for the knife, with the purpose of assisting in cutting certain parts, in addition to providing greater safety.
I had already produced parts that support a while ago, but after that there were problems with the computer connection impressora3D, resoolvi trabalhasr now that this support was leaning.
Utilized to support the operation of the lever principle, namely, multiplication of forces applied to this project. For that reason they requires less effort for cutting hard certain parts, such as frozen, for example.
Furthermore, because of the knife being stuck in the holder, it will always produce straight cuts in the vertical direction, the fact that this knife fixed on the bracket, this serves as a guide. Thus, she slips sideways, thereby resulting in greater safety for those who handles.
Also if one wants to cut vegetables with precise cuts resulting in perfect pieces in the cutting angle, this support well fulfills this function, as well as sausage salami, mortadella, ham, if one wants very fine and precise cuts, this support provides this condition.
To install the knife this support, the operation is very simple, because it does not require any tool. Simply just fit the cable in the niche in his support, and the tip of the knife in a recess exists at the other end. And to secure the cable in the holder, simply hold that cable holder, as a knife usually safer and ready, ready for use.
There is a limitation for this support to be usable knife; impressora3D produced by the prototype, which is plastic, could not stand to be used the way it is because it would break easily. The user of the knife with this support would require efforts beyond the mechanical resistance of the material used in making it.
How then do a demonstration of support with the knife, if he can not stand to be plastic? The solution was found to strengthen this support by means of grafts of metal parts (wires) fixed with epoxy putty, especially in places where they are subject to greater efforts. Both the reinforced support, as where the base supports the workpiece and also put wire from the head of the movable support, following the curvature at the top and extending to the end of the cable on the other side. With that, the two units were produced separate parts. In addition, all outside coating with epoxy putty, resulting in a rigid and sturdy.
Doing so has a lot of work, as you can see in the illustrations.
Provided for demonstration prototype was needed all these initiatives. Naturally, it is this form that this support could be marketed.
In tests, the performance proved satisfactory for cutting round vegetables such as carrots and turnips, as well as a sausage semicongelada. But, because the holder is sized for a small knife with a blade length of only 12 cm, the most she could cut products were up to 5 cm in diameter. There has to produce more support due to platform limitations printer. But that does not mean it is not possible to produce more support. Simply by producing parts, and then assemble.
To work well, this knife support must be manufactured with materials durable enough to cut frozen parts. Thus, both the holder and the base, or the whole set has to be material that resists cutting so that generally do not break.

The files for impressão3D are in stl format. For convenience, let also available in print mode of Makerware.
The movable part of the support, that will be embedded in the knife has dimensions that exceed the printing platform. For that reason they, was divided into two forms, with fitting to facilitate their union after being produced.
Thus, three files will be needed to form a whole, with the exception of the bolt, which of course being described as metallic, this bracket produced with plastic 3D printer is not meant to be used. It is for viewing purposes only.
To be usable, the demo level, has to be reinforced grafts and metal epoxy putty, the points where mechanical stresses are applied, the way it did, as seen in the illustrations, and full outer shell. Option is to paint later.
For this it is necessary to have tools such as a mini drill, sandpaper and epoxy putty.
