What would be the minimum tool sets you need to start leather crafts. No.2

With the article No.1, I explain what you need cut and make some hole to the leather.

As article No.2 I want to explain chemicals including wax you need to use.

The chemical I use most is “TOKONOLE” (The one in the photo is old bottle.), which is the glue to smooth up the back side/cutting edge of the leather. You can find an explanation by the maker of TOKONOLE here.

You can use your finger to apply it to the leather parts.
As far as I understand, you should use it to only back/edge of the leather.

After applying it, slick the surface with something hard. I use metal spoon or piece of glass. By slicking it, the surface becomes very flat and start to shine.

If the edge of the leather parts were not smooth, you could polish it with sand paper. I usually use paper of #400 to #800. Then apply the TOKONOLE again. You can repeat this process to get a smooth edge.

Once the TOKONOLE dried up, you can apply “Koba-wax” (“Koba” is a Japanese word for “edge”)to the edge.

I usually heat the edge with iron, then apply the wax directory several times. Then again use the metal spoon or piece of glass to polish it up.
