For quick trims or major grooming, a good pair of shears and scissors should be a part of your grooming kit.
Things to Consider:
Care -- Like clippers, shears and scissors should be cleaned and thoroughly dried after each use to prevent any rust.
Keep them sharp -- To cut like a pro, you need to have sharp scissors. After several cuts, you may need to take your scissors in and have them sharpened.
Horses only -- Because shears and scissors can become dull, it is best to keep them for hair cutting only, and avoid using them for other projects, which can dull them faster.
