Taps have a hard life and over time get dull or don't work s well. Ordered these to replace a tap that was beginning to fail. Find stainless steel is hard on them, and harder steel too. Rather than have a tap break I order new ones, and these will work well, and a decent price too.

Was a little surprised it did so well in metal that has broken other taps.
