Clippers get used for anything I can't cut easily with a knife. It makes no sense to hack away at tougher woody stems and branches, you end up doing more cell damage, so those take a swift clean cut from these clippers. This simple type has been a long time favourite, as one that lasts well and cuts most stems easily.
Ribbon scissors get the most use during wedding season. This pair has held up well, but I tend to go through these faster than any other tool I use. A few absent minded snips on something other than ribbon and these get dull and useless.
I use simple garden twine to tie my posies and bouquets with. Nothing fancy, I buy mine at the dollar store. A paddle wire has many uses, most especially I use this for garlands and wreaths but it is great for corsages in a pinch. I prefer a paddle wire to a spool, as it is less likely to roll off the work bench and get lost in the sea of leaves on the floor. And florist tape is a tape that binds flower stems together, you stretch it slightly which makes it hold onto itself tightly as you wrap it around and on top of itself. I prefer the plastic type, but there is also a paper one available. That one makes me mental as I find it dries out a bit and then snaps easily.
And there you have it, Trapped on a desert island with this small collection of tools, I could indeed whip up a floral masterpiece for you, no question!
