Abstract

Animals raised on a farm or harvested from the field need to be field dressed and skinned in order to obtain quality, unspoiled meat. This process is often interrupted due to a dull cutting blade that is not sized properly for the task. The OSAT cutting tool allows the user to cut only what is needed in a safe manner. This is accomplished by mounting a replaceable utility blade on a 3D printed handle with a guard. This design allows the user to cut just underneath the skin without puncturing organs.

Allowing the user to replace the blade ensures the tool is replaceable and easy to use time after time.

Bill of Materials

Utility blades can be ordered in bulk for little cost. TEKTON supplies 100 utility blades for $9.26. This is available here. http://www.amazon.com/TEKTON-82580-Utility-Dispenser-100-Piece/dp/B000NPPCPK/ref=sr_1_1?ie=UTF8&qid=1417533173&sr=8-1&keywords=utility+blades

The STL file for the part and openSCAD file can be found here:

Tools needed for fabrication of the OSAT

OpenSCAD
Slic3r

Technical Specifications and Assembly Instructions

The part takes about 30 minutes to print.
Once printed simply snap the utility blade into place as seen in the pictures.

Common Problems and Solutions

If needed the blade can be heated and pressed into the handle. If this is not possible the part may need to be scaled larger and reprinted.

Cost savings

A commercial equivalent to this cutting tool is available here for 12.61: http://www.amazon.com/Gerber-45924-E-Z-Zip-Sheath/dp/B000W0EW9I/ref=sr_1_3?s=industrial&ie=UTF8&qid=1417644410&sr=1-3&keywords=wyoming+knife

Blades are about 12 cents a piece if ordered in bulk.
About 4.5 meters of filament are needed to produce this part. This equates to about 50 cents.
Savings for this part are about 79 percent..
