HSS White Steel Knife Blade Blanks – 3mm Thick x 30cm Long (Pre-Heat Treated)
Take your custom knifemaking to the next level with our professional-grade HSS White Steel Knife Blade Blanks. High-Speed Steel (HSS), commonly referred to in machining and toolmaking as “White Steel” for its clean composition and bright grind, is renowned worldwide for its ability to hold a razor-sharp cutting edge through the most demanding tasks.
These premium flat stock bars are the perfect canvas for bladesmiths, DIY hobbyists, and professional makers looking to design high-performance kitchen cutlery, rugged bushcraft tools, utility knives, or custom daily-carry blades.
Why Choose Our HSS White Steel Blanks?
1. Pre-Heat Treated & Tempered
The complex heat treatment required for High-Speed Steel is notoriously difficult to perform in a standard home workshop. We have eliminated the risk of warping, cracking, or uneven crystallization. These blanks arrive professionally heat-treated, tempered, and ready to go directly to your grinder or sander.
2. Incredible Hardness & Edge Retention
HSS White Steel is engineered to withstand extreme friction, wear, and high operating temperatures without losing its hardness. This translates directly to a finished knife blade that keeps its biting edge significantly longer than standard carbon steels, requiring far less maintenance and sharpening.
3. Versatile 30cm Length & 3mm Thickness
The 30cm (approx. 11.8 inches) length provides ample material to layout large camp knives, chef’s knives, carving sets, or multiple smaller pocket knife blades. At a robust 3mm thickness, your finished knife will maintain excellent lateral strength, flex resistance, and balance.
4. Clean, Flat Surface Finish
Each blank is precision-milled and flattened, giving you a smooth, clean surface that is highly cooperative with layout ink, scribe lines, and precision drilling for your handle pins and lanyard tubes.
Tips for Working with Pre-Hardened HSS Steel:
Because this steel is already heat-treated to a very high hardness, we recommend the following working guidelines:
-
Keep it Cool: When grinding your bevels, dip the blade frequently in cold water. Letting the steel get too hot (turning blue) can ruin the temper.
-
Use Quality Abrasives: Utilize ceramic or high-quality zirconia sanding belts/files designed specifically for hardened tool steels to ensure efficient material removal.
-
Drill Before Detailing: If you need to drill pinholes for handle scales, use high-quality carbide drill bits at a slow speed with plenty of cutting lubricant to avoid work-hardening the steel.
