What is the ergonomic handle made of?

The ergonomic handles of the Steak Knife Set are made in pakkawood — a durable and waterproof thermoplastic — and finished with three stainless steel rivets. The ergonomic handles are a blend of real-wood aesthetic and easy-to-grip utility. And because each knife is made from a single bar of steel, the weight of the blade is well distributed, ensuring a firm hold while cutting through meat and other foods.
