Yep. While I don't uses chainsaws for a living (and don't work on them for a paycheck anymore), I don't have 'cases' for any of my larger saws. Heck, I don't have cases for my small saws either, except for two that just came to me with saws. One now has a little Poulan S25-CVA in it, and the other houses my 'beater' Homelite SXL-AO. They're good for carrying a 'just in case' (LOL) saw along with a bunch of non-saw stuff.......such as camping/hunting gear. Makes it so I can pile a bunch of crap on and around the saw without said crap getting oiley or cut up by a saw chain.
Here are a few of my large saw "carrying cases". I believe the green IHC was used as a crummy some time in its life. Not shown is the somewhat shiney black one that I bought new a year ago. Gotta snap a pic or two of that one before it's too beat up I guess. It's been hauling quite a few saws over the last year or so....
