Is there really a difference?

In kaelaria's Illusione 4/2g Video Review, he referred to this Cuban Crafters cutter http://www.cubancrafters.com/products.php/item_id/78. I liked the perfect cut promise and the fact that it catches the piece it cuts off, so I bought one.

I've only had it for about a month, but I'm very happy with it thus far and it was only $14.95 plus shipping. It's heavy in your hand and has a very tight feel to it, I swear I can feel it self sharpening with each cut.
