Budding Knife

A budding knife has a shorter, often curved blade and typically includes a bark lifter, a rounded spatula on the spine or handle used to peel bark open for T-budding. A grafting knife has a longer, straight blade ground for making long flat cuts on scion wood. Many professionals carry both.

The bark lifter opens the flaps of a T-cut without crushing the cambium underneath. After making the T incision in the rootstock, the lifter slips under the bark and gently separates it so the bud shield slides in cleanly. Using the blade tip instead bruises tissue and lowers take rates.

A single-bevel blade cuts flat and true against the wood, which produces the smooth, even surfaces that cambium-to-cambium contact requires. The flat side rides the cut. This is also why blades come in right-handed and left-handed grinds, so confirm the orientation before ordering.

Razor sharp, always. Bud take rates depend on clean cuts that crush no cells, and a dull blade tears tissue invisibly. Professional budders strop the blade frequently during a session, often every few dozen cuts, and hone on a fine stone at the day's start.

For budders making hundreds of cuts a day, the priorities are blade steel that holds an edge through a session, a handle shape that does not raise blisters, and a properly shaped bark lifter. Weight and balance matter more than appearance, and high-carbon steel sharpens faster in the field than harder stainless.

Most T-budding and chip budding happens in mid to late summer, when bark slips easily and mature buds are available from the current season's growth. Chip budding extends earlier and later since it does not depend on bark slip. Knife prep, including sharpening and stropping, should happen before the season opens.
