Removing file marks on bevel easily and quickly

[Natlek]

I've made a few knives so far and I file my bevels using a modified jig with a flap disc for the initial bulk removal and file for getting perfect bevels.
However after filing, the file marks are very tough to take out and require two hours just on the 80 grit paper, and the flap discs are too aggressive for this and can ruin the grind.. Is there something I'm missing or can the fiber discs/scotch Brite discs be used on the angle grinder to take the file marks out slightly quickly without being too aggressive.
Any advice is welcome.
Thanks

Let me give you same advice .You don't need that jig for angle grinder . I can bet that I will faster and better grind blade only with file .Never grind one side complete , it is much harder because you removing steel from large areas and when you turn blade to grind the other side ,blade will flex . Grind like this and I guarantee you will faster grind blade .Mark center line ,start to grind one side but be careful not to go with grind higher then /say 1 centimeters/ when you get to center line .Do that on other side .Then change grinding angle that way when you start to grind file to remove steel on the upper edge of the previous grind .When you hit center line again , stop .Do same on other side .Then again change the angle in same way as you do in previous step and there you are .In each step you remove small amount steel , that way is faster and you will have more even surface . Of course good file is must :thumbup:

check the stickies here and check You-Tube for explanations of how to draw file. I use a 14" Nicholson and a 12" Bahco bstard file and end up with a smooth satin finish. i drill my tang holes and attach the blank to a piece of angle iron which goes in a vise, clamped when level both ways. Your blade is laying on the angle and will not flex. with a good file, you can shape a bevel as fast as a grinder with a lot less mess. it takes some practice as your file is longways, across the blank, tilted to desired angle, then you are pulling or pushing the file the length of the blade. Bahco is owned by SnapOn and used to be part of the Sandvik group.

Thanks man! I'll try this on my tanto I'm currently working on I noticed the steel flexing but didn't think it made any difference. I see now.

I agree with most people. I also file with a jig, and don't use anything else for bevel making. I use an old file with deep large teeth. It takes away metal quick but leaves scoring in the metal. I work my way up in file corseness until metal is flat, and sandpaper the rest for around 15 min. This is my take on your question using only hand tools.
