I have several things that I garden with that I prize and things that my husband knows better than to touch.
1. My stainless steel border spade
2. My Felcos
3. My 18" Nejiri Gama Hoe (hand held weapon of destruction) I also have a 12" one too.
4. My Hori Hori Knife
5. My Dutch Perennial Divider
6. My Fiskars foam knee pads
7. My Foxgloves Gardening Gloves (I wear these religiously)
8. Round-up
I have lots of other implements of destruction that I like to use in the garden, but these are my favorite ones.
