This is my absolutely favorite garden tool, perfectly for dividing tubers. The sharp point can go to tiny areas with precision. Best part, it stays sharp and rust-free after dividing 1000 tubers and dipping 1000 times into 10% bleach.
The package comes with a protector so you can carry it in your pocket for cutting flowers as well.
This is the tool I can't live without. Made in Japan. Very limited quantity in stock.
