I have owned one of Tops Magnums (I believe it is the one you are referring to). Without question it is one of my favorite knives. It is exceptionally solid, sturdy and opens / closes with the best solid "clicking sounds" I have ever heard in folder. Plus it looks really tough. I would recommend it to anyone. You will love it.
I am not real impressed with the sheath however. It does the job but is nothing great. I am thinking of going with a custom black leather sheath.
