The garden trowel blade is the main working area. The blade has a sharpened edge which allows it to cut into soil or through roots. A garden trowel blade is large enough to hold a small amount of soil or compost.
A small hole is drilled into the end of some garden trowel handles so that the tool can be hung on a hook. A piece of string or a leather strip can be threaded through to aid hanging onto a larger hook.
Tang
A tang is a rounded bar that is often made into an “S” shape welded onto the blade to connect it to the handle. It increases durability by creating a stronger connection between the trowel handle and the trowel blade.
The distance created by the tang, in between the handle and the blade, provides sufficient space between the soil and the users knuckles, preventing them from getting dirty or scraping on stones.
A ladle garden trowel has an extra long tang for ease of scooping out dirt with the blade.
Some garden trowels have a depth gauge which is a series of measurements along the length of the blade with marked increments stating the distance. The depth gauge has two types of gradation: metric, ranging from 2cm to 10cm, and imperial, ranging from 1″ to 4″, one each side of the gauge.
A depth gauge helps you to plant at the right depth, for example bulbs which need to be a certain depth below the surface level.
