The thong hole is 1/4" in diameter when the liner is drilled out the hole is larger than 1/4". The original thong holes before the liner was added were 1/4" as well. Stupid dang trick the thieves pull and it is or should be easily recognizable. The original thong holes were beveled and some of those dumb asses that drill these knives don't know that and that is easily recognizable. It is a constant fight. In the end, good will win over evil.
