Household/Consumer meat processing equipment is geared twoard low cost, low volume use. Typically the mechanics of such devices are plastic or nylon, especially the wear parts like gears. They are really good for a few pounds of product here and there, or for your cleaned meat after a good hunting season. There is much less variety in the consumer market as there is in commercial and industrial markets. The products typcially are convenient, easy to use and affordable. To achieve this goal the equipment often uses lower cost (plastic vs metal) gears and parts. That said, the products are great for the needs of households.
