Hasegawa Wood Core Thermoplastic Elastomer (TPE) Cutting Board | FRK Series

If you are looking for the ultimate "Goldilocks" daily driver that balances knife edge protection with heavy-duty durability, the Hasegawa FRK Series is the definitive answer. Featuring a premium Thermoplastic Elastomer (TPE) surface, this board provides the excellent grip and forgiving nature of rubber—keeping your ingredients from slipping and protecting the delicate edges of high-carbon Japanese knives—while remaining vastly more resistant to deep scratches, odors, and stains than softer alternatives.

How does it compare to the FPEL and FSR boards? While the soft polyethylene (FPEL) offers a faster, snappier chopping feel, and the soft rubber (FSR) offers maximum laser-edge protection, the TPE surface of the FRK series is the perfect middle ground. It absorbs impact beautifully with a satisfying "thud," but has enough structural rebound to resist deep gouging, making it the ultimate all-purpose board for both professional prep stations and serious home cooks.

Key Features & Manufacturer Specs:

Thermoplastic Elastomer (TPE) Surface: Provides exceptional grip for slippery ingredients (like raw fish and poultry) while maintaining high resistance to deep cuts and mechanical damage.

Hermetically Sealed Wood Core: Hasegawa's patented structural kiln-dried wood core makes these boards 30-50% lighter than solid rubber boards, making washing and handling effortless.

Warp-Resistant Rigidity: Unlike solid synthetic boards that bow over time, the wood core acts as a skeleton, ensuring the board remains perfectly flat even in high-heat commercial environments.

SIAA Antimicrobial Certified: Meets ISO 22196 standards with Silver-Ion (Ag+) technology impregnated directly into the surface material to actively resist bacterial growth.

Thermal & Chemical Tolerance: Dishwasher safe and highly heat resistant up to 194°F (90°C). Safe for sterilization using boiling water, as well as chlorine-based or oxygen-based bleach.
