I have a pair of sharp fine nose pruning shears that I use to trim up most everything in the garden. They are
sharp and I trim everything from lettuce to Bonsai and other precise hand pruning activities. I recommend stainless blades and comfortable polypropylene ribbed grips with a brass thumb lock.

Some people want to work in the garden but do not have the strength in their hands. This is where a ratchet pruning
shears comes in. A lightweight yet durable hand shear, the ratchet cut hand shear easily prunes branches up to 3/4" in diameter. This type of hand shears is ideal for the precision pruning of flowers including roses.
All gardeners, from novice to professional, benefit greatly with this powerful hand device. The features should include a high carbon spring steel pruning blade, and Teflon coated to resist pruning residue buildup. I suggest
handles of fiberglass-reinforced nylon they are strong and light in weight. A ratchet cut mechanism works like the jack on your car. This mechanism multiplies your strength up to 700% when pruning with
this hand shears. This type of hand shear will allow people with arthritis, carpal tunnel or low hand strength to once again enjoy the pleasures of gardening. I have a pouch to keep my shears in, to make it easy to reach.
