Sharp tip for Portasol Pro Piezo

The damage

I was not aware that multi-layer tips of modern soldering irons cannot be activated with sal ammoniac and it caused stripping of the top anti-corrosive coating layer.

Sharpening the tip

Instead of putting the tip to the trash, I decided to make a sharp tip that is not provided by the manufacturer.

After several minutes of grinding on a rasper, I got a very sharp tip.

The new tip is much sharper than PP-1 DF, the sharpest double flat tip from Portasol:

I know, that such tip is slowly dissolved in the soldering iron and needs often sharping. But with this tip, Pro Piezo is an amazing tool for fine work. I purchased Portasol Pro Piezo because the distance between the holder and the tip (48mm between the grip and tip spike) is smaller than most other small soldering irons (both electric and gas) have. It allows precise soldering of small parts and prevents leverage efect amplifying of vibration of my shaky hands as well as accidental burn of my fingers.
