My two cents? The 101 looks like a great knife and a good option to the 110, 102, and 103. I will probably get one this coming year at some point. I like the idea. The pouch sheath does not bother me. I have a couple of hunting knives I have carried extensively and never had an issue, but the knives to sit deep and tight. My 102 and 120 both have flap sheaths and I do not care for that sheath, unless I am attaching the knife to the strap of my pack.
I can't help but to think that this knife in CTS-XHP would be simply awesome. I love that steel. It is one of my favorite stainless steels. I much prefer it to S30V, S35VN, 154CM and others. It is a stainless D2, basically, but the properties far exceed D2. It holds an edge better, is not too hard to sharpen (D2 can sometimes be a pain), is highly stain/rust resistant, polishes better than most steels, and has good toughness. It is really about perfect for the types of uses Buck knives are made for.
