At last! Stainless steel guillotine clippers that are tougher than my big shepherd-collie's nails! Spring loaded mechanism isn't flimsy either. Plastic, no-slip grip handles. A loop to hang them, if you like, although i stash my own away in a drawer until grooming day. The open / close stopper catch is my only - very slight - concern. It's plastic, rather than metal, so I worry it may wear down over time, preventing closure of the clippers when not in use. However, I'd rather carefully store these in their open position than break yet another weak or cheap pair, then buy another, and repeat a cycle that hurts my wallet and could eventually injure my pet as well.
