My wife gave me the wood handled smaller one, 15030-2, for Christmas 2010. I already had the larger green/black G10 version, 15020-1. Both are awaiting a bit of a touchup on the edge, as neither will raise many arm hairs now. They are users... I just don't enjoy sharpening D2. I've grossly carved wood, broken down boxes, opened mail,etc, with both. The larger one is substantially larger than the small one, which actually makes a more 'polite' EDC knife. While not a true 'Gent's' knife, the Goth like skull on the handle and blade pretty much end that use quickly, it is a handy size. I like my larger one better than my 950 Rift, too, but it is a larger folder, make no mistake. Both can be single handed - deployed by a thumb hole in the blade - retracted by pulling back on the AXIS lock. Both have liners that are ramped on top and jimped for a better bearing service in close work. Both allow LH/RH tip up only clip use - but are far better clipless (I remove all clips!). Both came sharp - and stayed that way for quite a while. My biggest complaint is the skull -but it is Waddell's symbol, and I accept it as a simple fact of life.
Don't forget their excellent fb - 15005-2 in walnut. Great sheath, too. The best attribute of all of the Bone Collector series is their price - big/little/fb (all in walnut) MSRP $155/$135/$125.
Yeah... I like them! Not much for serrated edges... I have dedicated saws.
