I'd like to see if anybody has things they find handy. I found these screws and always keep a few in the vest pocket I wear while banging about the garden. I use them for securing string, row cover all kinds of things. I don't need a screw driver they are easy to remove and to install in wood.

I've got sooo many handy things! Most of my handiest things are pretty, shall we say, low-tech:
I have many uses for a piece of bamboo
I have bubblewrap plugging up a badly-placed outlet in a rainbarrel, as well as insulating 'uncurtainable' windows
Old cotton sheets torn into strips are really handy for tying up tomatoes and raspberries, coralling fava beans...
at the end of the season the whole lot can go on the compost, or break down in place.
Hmm, this list looks more 'frugal', than 'handy'
Ok, officially handy: my multi-screwdriver: never again will I stomp back to the shed muttering #@#$%^^&Phillips, squaredrive etc

Old army shovel--this is my rake, hoe, shovel, machete, stool, fill-in-the-blank around the place.

hori hori knife http://www.amazon.com/Joe-SJHH1901-Hori-Hori-Landscaping-Digging/dp/B007PQNNJM/ref=pd_sim_lg_20 So useful, lasts so much longer than cheap plastic or cast metal trowels.

small vice grips (with wire cutter) and selection of screwdriver bits in a mini altoids tin (in my watch pocket). Will solve 80% of problems requiring tools on the farm.

And of course--duct tape, baling wire, and WD40. If you can't fix it with those three, it was too complicated to begin with...

robert ray, those screws do look incredibly useful, what are they called?

Kristine,
I found a box of them in an old junk store in Portland called the Happy Hippo. I don't even know if they are still there but it was a great store.

okay, thanks. i am going to keep my eyes open, i think those would be useful to me as i am just getting started into permaculture and i will be building all me beds, ect. this fall/in spring

They are called 'Wing Screws' and usually they do not have a sharp point. Haven't seen one in quite a while.

Those screws are so cool, I had to find some!
