I bought one. The five inch length of the Dumpster mutt really isn't very aluring right now for me. At least not when I have the SS4, the scrapper 6, and the 10 inch Dogfather that fill their respective niches very nicely.
I do have a habit of keeping a sheath knife in each car. I've got a Ranger RD-7 in the car the wife and I drive to work. And there's a SOG Seal Pup in our other car that only really gets driven by me.
Right now the plan is to hang onto the dumpster mutt for a little while and see what the secondary market is doing with them. I may be able to trade it for something I really want, like a Camp Tramp, a Scraper 7 when they come out, or simply sell it outright for something else. Of course I could fall in madly in love with the dumpster mutt and keep it in one of my cars in lieu of another blade. However, time will tell what happens.
