The Wilderness Guide is nice I would have to give the handle a try before I buy. IMO The M1 sub should be 1/8" also. The only TOPs knife I have is the Key B. I got it to give the brand a try. I love it. The handle is better then I thought it would be and the edge is good. I did thin it a little. I was suprised at how much I like it. The more I look at the M1 sub the more I like it but 3/16 is about the max I like in a full sized knife let alone one that small.
