A brush cutting blade having a curved slitter type/non-raker tape primary cutting tooth and a preceding appendage forming a combination depth gauge and small stem slitter. The primary tooth terminates over the blade body with the cutting edge provided by that curved portion of the tooth between its most lateral point and the point of termination over the blade body. The cutting edge is curved but outwardly directed in a slitter configuration throughout its length. The lateral point of the cutting edge determines the kerf width to prevent binding. The slitter cutting edge of the appendage is hook shaped to cut small willowy-type stems and the appendage has an upper inclined guide edge that guides the larger rigid-type stems into the primary cutting tooth. The uppermost point of this guide edge of the appendage provides a depth gauge for the primary cutting tooth. |
