Do these knives really cost $800? Ginsu are less than $50. You can buy a more than adequate set of real knives for about $3-400.

In college my roommate had a set of Cutco knives. I found them to be better suited for the shop than my kitchen. Although, I do have to admit that if you're looking for one tool to saw some dry wall or cut your shoe in half immediately before your food, Cutco may be the Rolls Royce of this market sector...
Since the original question was about taking a job selling these knives, I'd say take the job. Learning to sell an overpriced, inferior product will make you a heck of a sales person...
