Williams Sonoma's $30 "Reversible Meat Tenderizer" is described on its website as an "impressively weighty pounder" and "two tools in one." (It's also available on Amazon as the Leifheit Pro Meat Tenderizer Tool)
One side is smooth for flattening meats and poultry; the opposite side has "teeth" for tenderizing. Triple-plated-chrome construction over a zinc core adds heft.
Flattens and tenderizes meats and crushes other foods such as garlic and nuts.
Ergonomic handle provides leverage and a comfortable grip.
Crafted of dishwasher-safe chrome with a zinc core.
It's 6 and one quarter inches "high".
