I used this style chisel working in boat shops for years. Wouldn't be my go to for fine work, you can really abuse this thing though! Kept an edge pretty well and I found the side blade useful for cutting open bucket lids. The opposing side has a nice wide edge you can really beat the heck out of with a hammer.
This particular chisel is probably the most dangerous hand tool I own. I purchased it because I needed an all-purpose framing chisel and this one was reasonably priced. I keep my all-purpose framing chisel in my apron and mostly use it for prying, scraping and gouging out misc. wood. I don't keep it particularly sharp on purpose. The problem I found with this chisel is mainly the sharpened side edge. You cannot go blindly grabbing it out of your apron. I cut my knuckle almost to the bone just getting it out of the packaging. After that, I took it out and purposely dulled the side edge of the chisel. If your working in a shop or don't have to carry it around with you it may be okay. I think this is a product that should have been left on the drawing board.
