That’s not medical at all — it’s a meat tenderizer clamp (sometimes called a scissor-style steak tenderizer).
🥩 Scissor Meat Tenderizer
What It Does
The two square plates with pyramid spikes are designed to:
-
Grip a piece of meat
-
Press and pierce the surface fibers
-
Break down tough muscle tissue
You squeeze the handles like scissors and clamp down on the meat. The spikes puncture it evenly, helping:
-
Tenderize tougher cuts
-
Allow marinades to penetrate better
-
Reduce cooking time
