The Aesculap GT343 is a #7 SnapOn blade set for animal grooming with a 3.2 mm cutting length and a 40 mm cutting width. Its comb has alternating long and short teeth, giving this model the recognizable skip-tooth pattern. The exact GT343 number identifies this tooth arrangement as well as the blade size when selecting a replacement cutting head.

The SnapOn connection allows the blade to be fitted to compatible clippers and exchanged without tools. Made in Suhl, Germany, it uses carbon steel cutting plates with precision-machined working surfaces. The finish of those surfaces and the shape of the teeth support a consistent cut as the blade moves through the coat. Professional resharpening is possible when the cutting edges need attention.

For regular grooming use, clean out accumulated hair before it interferes with the movement of the cutting plates. Aesculap's instructions call for a soft cloth or brush to clear both plates and the tooth gaps, followed by light lubrication with GT604 blade oil. Maintain lubrication during clipping and store the blade oiled in a dry location. Routine cleaning does not require unscrewing the SnapOn assembly; leave sharpening and internal assembly work to a qualified service provider.
