I did not know about the counterfeit Cardsharp 2 knives before I bought some :( 1 was purchased from eBay seller digittradeusason for $4.99, and a 5pk was bought from eBay seller refineryworkwear for $17.50. They all have the 4 groove safety latch, the SAME serial # of 001041752, and all were packaged in a plain clear cellophane envelope. No cardboard cover or insert.
