Fintiso Santoku Knife 7 Inch (S35VN Steel, Blue Celestial Resin Handle)

What makes S35VN steel superior to standard kitchen knife steel?

S35VN powder steel offers significant advantages over traditional steel. It achieves 62 Rockwell hardness whilst maintaining toughness that prevents chipping. The powder metallurgy process creates uniform carbide distribution throughout the steel. This results in superior edge retention, corrosion resistance and impact strength. Unlike carbon steel that requires frequent sharpening, S35VN maintains its razor edge much longer.

How should I care for and maintain this knife?

Hand wash immediately after use with warm soapy water and dry thoroughly. Avoid dishwashers as they can damage the handle materials and dull the blade. Store in a knife block or magnetic strip to protect the edge. The celestial resin handle withstands water but should be dried completely. Occasional honing maintains the edge, though professional sharpening may be needed less frequently than with standard steel.

Is the 7-inch blade size suitable for all kitchen tasks?

The 7-inch santoku blade provides excellent versatility for most kitchen tasks. It handles slicing, dicing and chopping vegetables efficiently whilst being manageable for detailed work. The size suits both small and large ingredients. However, for very large items like whole chickens or melons, a longer chef's knife might be more suitable. For intricate tasks like paring, a smaller knife would be better.

Why does each handle look different?

Each blue celestial resin and yellow wood handle is individually cast during manufacturing. The resin contains natural variations that create unique patterns and colour distributions. This means no two knives are identical in appearance. The casting process cannot be perfectly controlled, resulting in one-of-a-kind handles. This adds character whilst maintaining the same ergonomic properties and durability across all knives.

What is the significance of the 8-12 degree edge angle?

The 8-12 degree per side edge angle creates an extremely sharp cutting edge totalling 16-24 degrees. This is significantly more acute than typical Western knives which use 20-25 degrees per side. The sharper angle reduces cutting resistance and creates cleaner cuts. However, it requires more careful handling and storage to prevent damage. The S35VN steel's toughness allows this acute angle without excessive fragility.

Can this knife handle heavy-duty tasks like bone cutting?

This santoku knife is designed for slicing, dicing and chopping soft to medium-hard ingredients. Whilst the S35VN steel is tough, the thin blade geometry and acute edge angle make it unsuitable for heavy chopping or bone cutting. Use it for vegetables, boneless meats, fish and herbs. For bones, joints or frozen foods, use a cleaver or heavy-duty chef's knife to avoid damaging the precision edge.

How does the anti-stick surface actually work?

The sandblasted finish creates microscopic texture that reduces surface contact with food. Double-sided grooves channel air and moisture, breaking the suction that causes sticking. This matte surface also eliminates the smooth finish that food typically adheres to. The combination reduces drag during cutting and makes cleaning easier. Unlike non-stick coatings, this mechanical surface treatment won't wear off with use.

What warranty protection comes with this knife?

Fintiso provides 100% worry-free warranty service covering manufacturing defects and quality issues. Additionally, there's a 180-day refund policy allowing returns within six months of purchase.
