A seal formed between at least two blades in the turbine of a turbine engine, a first turbine blade and a second turbine blade, wherein one of the turbine blades comprises a turbine rotor blade (126) and the other turbine blade comprises a turbine stator blade (128), and wherein a trench cavity (150) and the seal is formed between the first turbine blade and the second turbine blade when first turbine blade is circumferentially aligned with the second turbine blade, the seal comprising: a cutter tooth (160) and a honeycomb (162); wherein: the cutter tooth (160) comprises an axially extending rigid tooth that is positioned on one of the first turbine blade and the second turbine blade and the honeycomb (162) comprises an abradable material that is positioned on the other of the first turbine blade and the second turbine blade; and the cutter tooth (160) and the honeycomb (162) are positioned such that each opposes the other across the trench cavity (150) when the first turbine blade is circumferentially aligned with the second turbine blade.
