Make a Knife with the Stock Removal Method
"The stock removal method is woodcarving with metal. You take away everything that is not a knife.

Stock Removal vs. Forging
Stock removal knifemaking starts with flat steel bar at final thickness and removes material to achieve the blade profile and bevel, rather than forging the steel to shape. It requires no forge or anvil — an angle grinder, files, sandpaper, and a drill cover 90% of the work. 1084 high carbon steel is the standard beginner choice: easy to grind, heat-treatable with a propane torch, forgiving of minor temperature errors, takes a sharp edge readily.

Draw and Cut the Profile
Trace the blade outline and cut with an angle grinder or bandsaw.
Draw and Cut the Profile
Draw the blade profile on the steel bar with a marker — include the blade, ricasso (the unsharpened area behind the edge), and tang (the handle extension). Cut the outline with an angle grinder fitted with a cutoff wheel. Keep cuts outside the line — clean up to the line with a belt grinder or files. Drill handle pin holes and any finger guard holes before profiling is complete.
Grind the Bevel
File or grind a flat, scandi, or hollow bevel from the edge to the spine.
Grind the Bevel
Mark the centerline along the blade edge and scribe bevel lines with a marker. Grind or file the bevel from the edge up toward the spine. A scandi grind (flat bevel from edge to spine at a consistent angle) is easiest for beginners. Leave 1/32 inch of thickness at the edge before heat treatment — grinding too thin causes warp during hardening.
Heat Treat — Harden and Temper
Heat to non-magnetic, quench in warm canola oil, then temper at 375 F.
Heat Treat — Harden and Temper
Normalize the steel twice before hardening: heat to non-magnetic (check with a magnet), air cool twice. For hardening: heat evenly along the blade to bright cherry red (non-magnetic, around 1475°F). Quench edge-first into warm canola oil (warm oil reduces warping). The blade should be hard enough to skate a file across the surface. Immediately temper in an oven at 375°F for 2 hours to relieve stress.
Handle, Sharpen, and Finish
Shape and attach handle scales, then sharpen on whetstones.
Handle, Sharpen, and Finish
Cut two handle scale blanks from wood, G-10, or stabilized wood. Drill pin holes to match the tang. Epoxy the scales, clamp, and pin with brass or mosaic pins. Shape the handle on a belt grinder or with files and sandpaper through 400 grit. Sharpen on whetstones to 8000 grit and strop on leather. A 1084 kitchen knife properly heat-treated sharpens to a hair-shaving edge.
Materials List
1084 high carbon steel bar — 3/16 inch thick
Angle grinder with cutoff and grinding wheels
Files — bastard and second cut
Sandpaper through 400-grit
Canola oil for quench — 2 liters in a heat-safe container
Propane torch (MAP gas for higher BTU)
Magnet on a stick for non-magnetic test
Handle material — wood, G-10, or stabilized wood
Tempering Must Happen Within 30 Minutes of Quench Freshly hardened steel is fully hard but very brittle — it can snap under flex. Tempering relieves the brittleness by heating to 375°F (2 hours). Do not wait overnight to temper — an untempered blade left overnight can crack from internal stress. Move from quench bucket to the oven within 30 minutes.
"The grind is the work. The heat treat is the reward. The sharpening is the proof.
