Two Thai cooking tasks justify the time and money required to buy some good kitchen scissors. Snipping hanks of softened bean thread noodles into manageable two-inch lengths is one job, and cutting wild lime leaves crosswise into infinitesimal threads is the other. Sure, you don’t do either of those jobs on a daily basis, but perhaps that’s because you have not done them with a pair of kitchen scissors dedicated to culinary tasks. Look in kitchen equipment stores and hardware stores for a heavy pair that is dishwasher safe, and then keep it both in and for the kitchen, resisting any urges to carry it off to the den for wrapping birthday presents. Once you have a pair, you will find many other kitchen uses for them.
