170 mm Chef Knife Blade Santoku Blank Powder Steel Hidden Tang DIY Custom Kitchen Knives

Chef Knife Blade Santoku Blank Powder Steel

Create your own custom Japanese-style kitchen knife with this 170mm Santoku knife blank made from powder steel. Designed for knife makers and DIY enthusiasts, this unhandled blade blank provides a strong foundation for building a personalized Santoku chef knife with the handle material, shape, and finish of your choice.

The Santoku is one of the most versatile Japanese kitchen knife designs. Its compact 170mm blade is well suited to everyday kitchen tasks including slicing vegetables, cutting meat, preparing fish, chopping herbs, and general food preparation. This makes the Santoku an excellent choice for makers who want to build a practical custom kitchen knife that combines precision, maneuverability, and a distinctive Japanese-inspired profile.

Powder Steel Santoku Blade

The blade is made from powder steel, offering the characteristics sought by knife makers who want to create a premium custom kitchen knife. Powder metallurgy steels are widely appreciated in modern knife making for their refined microstructure and potential for excellent edge performance when properly heat treated and finished.

This blade blank gives you the opportunity to build a knife around your own preferences rather than purchasing a finished production knife. Choose your own handle material, shape, dimensions, and finishing details to create a truly individual Santoku.

170mm Santoku Blade Length

With a 170mm blade length, this blank has the classic compact proportions that make Santoku knives popular for home kitchens and professional food preparation.

A 170mm blade provides a useful balance between cutting surface and maneuverability. It is long enough for most everyday vegetables and boneless proteins while remaining comfortable to control on a standard cutting board.

The relatively compact blade can also be an excellent choice for cooks who prefer a more agile kitchen knife than a traditional 210mm or 240mm chef knife.

Hidden Tang Construction

This Santoku blade blank features hidden tang construction, allowing the tang to be enclosed within a custom-made handle.

Hidden tang construction gives knife makers considerable freedom when designing the handle. You can select your own wood, stabilized wood, composite, or other suitable handle material and create a shape that fits your preferred grip.

The 69mm tang length provides the foundation for constructing a compact custom handle while maintaining the clean appearance associated with hidden-tang Japanese-style knives.

2.2mm Blade Thickness

The blade has a 2.2mm thickness, providing a practical starting point for a kitchen knife designed for controlled slicing and chopping.

The relatively slim profile is appropriate for precision food preparation while still providing a substantial blade structure for a custom knife project. Final geometry, edge thickness, bevel configuration, and performance will depend on the maker’s grinding, heat treatment, sharpening, and finishing process.
