Professional Spring-Loaded Meat Tenderizer

Product Description: Will it alter the shape of the meat?
It creates tiny channels within the meat rather than flattening it; consequently, the meat becomes more receptive to marinades while retaining a shape very close to its original form.
Do the blades remain exposed after use?
The blades automatically retract once the downward pressure is released. After washing and drying the tool, please be sure to reattach the protective cover before storing it.
How should I clean it?
Please rinse the tool immediately after use, or soak it briefly in warm, soapy water. Afterward, use a small brush to clean between the blades, and allow it to dry completely before storing.
