After much research, I purchased a Portasol II disbudding iron, as many breeders speak very highly of it, plus I liked the fact that it seems to be lighter weight, and without the cord, easier to handle. So a couple weeks ago, a friend of mine and I attempted to use it disbud one of my kids, and we were surprised at how thin the edge of the tip is (not sure how to describe it, but I believe the literature calls it "a cutting edge") Anyway, as we started to disbud this kid, it seemed like the iron wasn't cauterizing the skin enough; it burned through, then the skin was sort of able to move around around the burn :? So we ended up finishing up with the rhinehart iron. So my question is... has anyone had any experience with this type of iron?? If so, is the technique different?? I'd really like to be able to use it as it seems much easier to handle..just not sure how... Thanks!
