It's not an MLM or pyramid scheme; it is regular sales employment. You're not getting other people to sell them for you nor are you encouraged to find others looking to join the sales team. It just sucks dick because the pay is shit (and they go through hoops to pay you less or nothing; which is where the scam part comes in), they treat you like shit, and you have to basically sell them door-to-door.
It's stupid because the knives are great products; I still have my sample set because they actually rock. They just only sell them like Tupperware clubs and only market them via word of mouth. They'd be making bank if they just sold them to retailers instead of fucking with young people looking for their first job.
