thanks for the video, I have raised some doubts, what kind of acid used to reveal the hammon?, that hits the back end, to straighten the road? and one more where I get one of those sharpening stones? can answer by private message if you wish thanks in advance

@clorsa I don't know what kind of acid Mr. Bolf uses, but ferric chloride is very common (and it looks like he might be using it). Some people also use lemon juice.

@hesparus He's using nitric acid.
