        file1.jpgThis used to be my Dad's and I've had it for years, but never knew what it was for. Some one on here will probably know. It's the same on both sides and has one safe edge. The writing at the top looks like "Dreadnought". Sorry for the poor quality photos.file2.jpg

            That will be a Mill tooth / curved cut file. Used for fast cutting softer materials like aluminium alloy and commonly used for shaping body filler.

              Yes agree with John Brown 17. I used mine on car bodywork many years ago when lead loading.

                I thought" Millen" cut files had the straight teeth and Dreadnought the curved ones

                  It's certainly what Dad called a Dreadnought file.

                    Also known to be used by farriers / blacksmiths when re-shoeing horses.

                      Very likely an Aven Trimmatool blade, a Surform rival from the 50's and 60's, as far as I can remember!, sold a few in my time.

                        We used to use them on aircraft aluminium panels. They used to slice your fingers when your hand continued pushing, but the file stopped moving. We also used Millenicut files. These has straight teeth in sets of 5 , 4 teeth were normal and the 5th was serrated.

                        Dreadnaughts were a very coarse file, followed by bastards, straight cut and second cut. File cards were used to remove swarf from the file and chalk rubbed onto the file to a) stop swarf sticking to the file and b) make the cut finer for finishing.

                        Re-cut files had been acid dipped to "sharpen" used files.

                            As well as soft alloys, they work on wood, I have flat and half round. I used to have a double sided flat with a different coarseness each side.

                              I used em years ago on lead loaded car bodies, they were known as dreadnoughts but not sure if that's a reference to the make or type. As mentioned, they do make a mess of your fingers if the file stops quickly and you don't.

                                I have a flat blade of steel the lengthe of the file and it has a file handle,there are holes at both ends to which two flat dreadnought blades are attached with small bolts.One of the blades is flat and the other is half round which bolt on one at a time.I have used these blades on steel and if there is a lot to remove and shape they are great.
