I have a Japanese garden knife that I got as a gift from Brett for some irises I sent him. I don't have a picture of it, but it is a really handy tool in the garden for weeding, dividing irises, or thinning them. I use it a lot. It is like a knife with a serrated edge on one side, and a sharp edge on the other, and a nice pointed end for digging and weeding. I also have a sharp pointed small shovel that my dad made years ago to dig up small trees to transplant that is very handy.
