The correct sharpening (honing) angle – 30°
The difference between grinding and sharpening (honing)
How to use a honing guide for consistent results
What a burr is and how to remove it
Why sharp tools are safer and easier to control
🧰 Tools, Equipment & Materials
🔧 Tools:
Honing guide
Protrusion guide (DIY or bought)
Diamond stone (1000 / 400 grit)
Bevel edge chisel
🦺 PPE:
Safety awareness (hands behind cutting edge at all times)
🪵 Materials:
Scrap timber (for testing sharpness)
📐 Key Concept
👉 Sharpening angle (secondary bevel) = 30°
This is the angle we are creating after grinding.
Consistency is more important than speed — that’s why we use guides.

🔄 Step-by-Step Method
1️⃣ Set the Angle
Use your protrusion guide to set the chisel in the honing guide at 30°.
✔ This ensures consistency every time.
2️⃣ Secure the Chisel
Place the chisel into the honing guide
Make sure it sits correctly in the grooves
Tighten carefully (don’t overtighten)
3️⃣ Choose Your Stone
Diamond stone (recommended – clean and simple)
Oil stone (works well but can be messy)
4️⃣ Sharpen the Edge
Place the chisel flat on the stone
Roll it back and forth smoothly
Use a figure-of-eight motion to avoid uneven wear
👉 You’ll start to see a burr forming on the edge
5️⃣ Check for the Burr
The burr is:
a fine edge of metal pushed over during sharpening
✔ This tells you the edge is ready
6️⃣ Remove the Burr
Flip the chisel over
Keep the back completely flat
Pull it back across the stone gently
7️⃣ Test the Sharpness
Use end grain timber:
✔ Clean cut = sharp
✔ Smooth feel = sharp
