I am going to try out a new Angle Grinder's Belt Sander attachment which I bought online recently.
This is the standard assembly.
The platen is set to grind off materials downward.
I am going to modify it using a bracket to grind off materials away from me.
This Bracket!
Ok, let's assemble them together and see if it works.
It works!
Put three fingers on this surface and press gently on the belt sander. Try tilting it just like sharpening the knife on a whetstone.
Use a marker (sharpie) on the cutting edge surface to see if it is the correct angle (tilting angle).
Apply a light pass on the belt sander to see if the angle is too wide or narrow.
Once the angle is establish, continue sharpening and focus on producing the burrs.
This is the burrs.
Continue sharpening with a light pass on the belt sander.
This is to remove most of the burrs.
Let the knife gently slice a piece of wood or cardboard to remove most of the burrs.
and a few more laps on the belt sander
At this stage, I will strop the knife on a leather strop that I made from my own used leather belt.
To begin with, I rub a polishing compound (sorry guys, I forgot to show how the polishing compound looks like) and gently let the knife pass lightly on the leather strop.
like so
I normally test the sharpness of the knife by slicing a piece of paper. But here, I'll show you 4 ways of testing the sharpness of a knife.
Test 1: The bite on the fingernail. (WARNING! Don't do this if you are not sure how to do it. Whoever is watching this is responsible for their own safety)
Test 2: The Shaving. (WARNING! Don't do this if you are not sure how to do it. Whoever is watching this is responsible for their own safety)
Test 3: Chopping on Vegetable/Soft Leaf. (WARNING! Don't do this if you are not sure how to do it. Whoever is watching this is responsible for their own safety)
Test 4: Slicing paper. (WARNING! Don't do this if you are not sure how to do it. Whoever is watching this is responsible for their own safety)
