If you’re looking for quality knife blanks, handle scales, and replacement parts, Thrifty Knife offers affordable gear to get you started on your custom creations.

Step 1: Choose Your Knife Style

Before picking up any tools, decide what type of knife you want to make. Consider:

Purpose – Hunting, bushcraft, kitchen, EDC?
Blade Shape – Drop point, tanto, clip point?
Size – Small utility blade or large chopper?

Sketch your design on paper or use a template to guide your build.

Step 2: Select the Right Steel

The type of steel will determine your knife’s durability, sharpness, and maintenance needs.

Carbon Steel – Easy to sharpen and holds a great edge, but prone to rust.
Stainless Steel – Corrosion-resistant and low-maintenance, ideal for outdoor use.
Tool Steel (like 1095 or D2) – Excellent for toughness and edge retention.

Tip: For beginners, 1084 high carbon steel is forgiving and easy to heat treat at home.

Step 3: Shaping the Blade

This step is called “profiling.” After cutting your steel to rough shape (using an angle grinder, hacksaw, or bandsaw), refine the outline using files or a belt grinder.

Tools:

Angle grinder or bandsaw
Belt grinder or metal file
Clamps and vise

Mark your center line on the blade to guide the bevels you’ll grind later.

Step 4: Grinding the Bevels

This is where your blade starts taking shape.

Use a belt grinder or file to remove material from the edge, tapering it down to a sharp point.
Keep the bevels even and symmetrical.
Dip the blade in water frequently to prevent overheating.

Step 5: Heat Treating

To harden the steel:

Normalize – Heat the blade to a dull red glow and let it air cool.
Quench – Reheat until non-magnetic, then quickly quench in oil.
Temper – Bake the blade in an oven at 350–450°F for 1–2 hours to reduce brittleness.

Safety note: Heat treating can be dangerous—use protective gear and ventilate your workspace.

Step 6: Adding the Handle

Knife handles (called “scales”) can be made from wood, G-10, Micarta, bone, or synthetic materials.

Drill holes in the tang of the knife for pins or bolts.
Epoxy the scales to each side.
Clamp tightly and let cure for at least 24 hours.
Shape and sand the handle to your desired grip.

Step 7: Finishing Touches

Sharpen the blade with a whetstone or sharpening system.
Polish or etch the blade for aesthetics.
Apply a protective oil to the blade and handle.
