love my swamp warden. the Izula and Scrapavore are both a noticable bit smaller and lighter, the Scrapavore doesnt feel the best in the hand, but how much cutting are you really going to be doing with it? Long hours behind it might cause some hot spots. AZWelke makes awesome sheaths, cheap, plus he is a forum member, cant reccommend him enough. Im sure others do good works, but my experience is with his goods.
Search, pics of both are posted.
Warden rides neck carry everyday as a heavy but box cutter for me so I dont dull up my Microtech Socom folder. When I camp and hike thouh my Becker Necker is my go to knife. I do everythign with that knife, especailly with the bottle opening feature......
