Like any other artist, a flower designer needs different tools!
There are a variety of tools used for cutting flowers. These are the tools I use most often for cutting the variety of flowers I choose.
I use pruning shears for cutting flowers from the plant , and also heavy stems such as evergreens. This tool easily cuts through the bark and makes a clean cut. I sometimes use pruning shears to cut flowers underwater.
Ribbon scissors are used exclusively for ribbon. This pair of scissors need to be very sharp. This allows a clean, sharp cut on the ribbon. I try not to use these on wired ribbon. This may dull the scissors. I may cut the ribbon with a pair of shears, pull through the wire on the end, then make a clean, angle cut on the ribbon ends.
Shears are another pair of scissors that are used by designers. My Mother used shears, instead of a knife, to design flower arrangements. These shears are multipurpose. They can cut flowers, thin wire, plastic, and other thin solid surfaces. Shears are usually serrated. This can cut through heavier objects.
Another cutting tool is the florist knife. There are different styles of knives. The knife I used is a foldable knife. It is very sharp. It takes practice to use a knife. To use a knife, learn the hold the knife at a 45 degree angle against the stem of the flower. The trick is to pull the stem against the stationary knife. This helps prevent cutting your thumb.
Remember, practice is the best way to learn control and speed when using the tools for flower designing.
