The Kasumi Boxed Knife Set SM-20012 represents authentic Japanese craftsmanship from Sumikama Cutlery in Seki. This professional-grade set features 32-layer Damascus steel construction with a VG-10 high carbon steel core.
Each blade maintains 59-60 Rockwell hardness and features a precise 15-degree bevel angle for exceptional sharpness. The set includes a versatile 20cm chef's knife and a 12cm utility knife for various kitchen tasks.
Full tang construction ensures perfect balance whilst laminated wooden handles provide comfortable grip. Both knives arrive in an elegant black presentation box, making this set ideal for gifting or personal use.
Damascus steel features multiple layers of steel folded together, creating distinctive patterns and superior performance. This set uses 32 layers with a VG-10 high carbon core that provides exceptional edge retention. The layered construction also helps prevent food from sticking to the blade and creates beautiful cloud-like patterns that make each knife unique.
These knives arrive razor-sharp with a 15-degree bevel angle per side. The VG-10 steel core maintains this sharpness exceptionally well due to its 59-60 Rockwell hardness rating. Users report being able to slice paper and perform detailed cutting tasks immediately upon unboxing without any additional sharpening required.
No, the laminated wooden handles should not be placed in dishwashers. Hand washing with warm soapy water and immediate drying is recommended to maintain the handle's integrity and appearance. The laminated construction provides moisture resistance, but prolonged exposure to heat and water in dishwashers can damage the wood over time.
The 20cm chef's knife serves as the primary workhorse for most kitchen tasks including chopping vegetables, slicing meat, dicing onions and general food preparation. Its size and weight make it suitable for both delicate work and heavier chopping tasks. The sharp edge and balanced design allow for efficient rocking motions when mincing herbs or garlic.
Clean the blades immediately after use with warm water and mild soap, then dry thoroughly to prevent water spots. Avoid abrasive cleaners or scouring pads that could damage the Damascus pattern. Store knives in the provided box or use knife guards to protect the edges. Regular honing with a steel rod will maintain the sharp edge between sharpenings.
The 12cm utility knife features a thinner, narrower blade ideal for detailed work like filleting small fish, trimming meat, or precise vegetable preparation. The 20cm chef's knife offers more weight and blade surface for general cutting, chopping and slicing tasks. Together, they provide complete coverage for most kitchen requirements from delicate to heavy-duty tasks.
Yes, these knives meet professional standards with their VG-10 steel construction and precise manufacturing. The 59-60 Rockwell hardness and 15-degree bevel angle provide performance comparable to much more expensive professional knives. However, the wooden handles may require more careful maintenance in busy commercial environments compared to synthetic alternatives.
The VG-10 steel core provides excellent edge retention, typically requiring professional sharpening only every 6-12 months with regular home use. Regular honing with a steel rod between uses will maintain the sharp edge much longer. The high carbon content makes these knives easier to sharpen than many stainless steel alternatives when professional sharpening is eventually needed.
