Got a new tool for Christmas! It’s a multi-purpose garden knife from Jackson Tools, the professional tools division of Ames True Temper.
I will say, this tool is a hybrid version between a narrow hand shovel and the traditional hori hori ; the traditional Japanese flat blade knife used to work the garden soil.
If you need to tamp down, pry, dig, shovel, plant, open, cut, design, measure, mark, weed, etc. with minimal soil disturbance and/or in small area like a container, this is the tool you need.
Your favorite blue hardware store sells a lighter version for few dollars less, under the Ames brand, but you will not have the reinforced handle and the well-designed sleeve.
