I was totally wrong about those $30 shears from the beauty supply store.
For years I stuck with my expensive professional pair, thinking anything cheaper would ruin a cut. My apprentice brought in a set of 'Mizu' shears she got on sale, and I let her use them on a basic trim last Tuesday. The glide and the edge were shockingly good. I ended up borrowing them for a men's scissor-over-comb cut and the control was perfect. Has anyone else found a budget tool that completely changed their mind?
