Tom Mayo Dr. Death. I love the ease of carry, and the amount of blade that gets packed into such a slim profile. I find that I need a a fine tip more often than not, and yet the stock is thick enough for me to not worry about pullin' up the occasional staple or two. I also love the SUPER low profile pocket clip, and this very knife has sold me on tip down carry.
While I prefer a hole for an opener, the thumbstuds on the Dr. Death are the lowest profile I have ever seen. everything about it visually says to me, "be careful with it", but when I hear the locking "clunk" of the lockbar, it is all business, and I haven't been afraid to use it on anything yet.
between that, and my Sibert Pocket Rocket, there's not much I can't accomplish. The pocket rocket is like a tank, and has all the details, and build quality found and associated with anything Sibert. I Dunno if I have ever had a stronger folder. The details alone on this knife impress me, and just like anything else Shane makes, you can't really hurt it. I once asked him who he heat treats with, and I dunno what they do to it, but the edge retention on Shanes's S30V blades is the best I have found. I have used one other of his knives (a fixed blade) harder than my folder, and it still shaves. I have heard and read the same sort of edge retention stories before, but until I experienced it for myself, I really was a non-believer. After chopping, prying (yeah I understand that's not what knives are for), cutting, and hacking at branches, I have no chips, and the edges still shave with minimal effort.
For finer tasks, and honestly for the straight up pleasure of owning, I have my Rick Nowland slip-joint. It is my first slip-joint, and first slippie, and is absolutely wonderful. I am starting to understand why they are so popular, and am looking forward to my second Nowland.
