I own 2 of them. 1 I’ve had for along time, the other I purchased about a year ago. The guy who designed them and owned the company early on is a local guy here in Saint cloud. He had a supply of hold over ones he had and I purchased about 5 of them from him and gave 4 of them as gifts. I believe the new company owner has mad a few changes in them from the original. The are Great. The raised surface makes it really easy to get the knife at a perfect angle. The groves and channel around the edge keeps all the mess away from the cleaning area and the large slot is a great area to either hold the fish being cleaned or to put the finished fillets after. Well worth the money I paid.
If anyone wants to know what these look like. Here is the web site:

Mike’s repair shop here in Saint cloud is listed as a dealer of them and where I picked up 5 of them last year. I believe he is the original owner of the company.
