If you search the forums for 'Sheffield 12010', you'll find all my ranting on this little gem.I EDC this tool, along with a Crosscut and Victorinox one-hand Trekker. Mine has the same swirl marks seen on yours. They originally had cheesy rubber stick-on grips that come undone and fall off. Mine were red, and had the model number of the tool on them. So, when they fall off, so does all identification.They are functionally identical to the 'Great Neck 12-in-1 Mini Multi Tool' which can be found on the K-Mart website (and sometimes in stock at your local K-Marts.http://www.kmart.com/great-neck-12-in-1-mini-multi-tool/p-010W012825630001P?prdNo=1&blockNo=1&blockType=G1
Zed, is yours riveted?
