Hi, I saw these types of forges many time on czech blacksmith's sites and saw that the "clinker breaker" isn't like the ones we have in north america.
They have, instead of the clinker breaker, a swirling thing. We can see them on Branco's site: http://www.branco.cz/smith-forges-spare.htm
My question is, does it swirl when the air is passing through the pipe or it is only turning with a handle to break the clinkers?

And, if it swirls with the air, what is its purpose? No accumulation of clinkers? Creates a better blast on coal?

Thanks

I used them many times while in Europe. They do not swirl. They are to make the air swirl. Clinkers still form. I wouldn't say that it makes a better blast, but they do work nicely.
