 Five simple steps to quickly sharpen your card scraper Hola woodworkers Paul Carlson here a small workshop guy There must be 500 videos out on YouTube about how to sharpen a card scraper You can watch other videos about what are they an hour they use to get one sharpen Son and this is from Matthew Cremona as part of step one take a sharpie and mark one edge Actually mark both your edges. I'm only going to show one edge because I got a three-minute limit run that across a fine wood file At 90 degrees you can do that freehand if you want to do that just put it in a vice and run that over your The file over it or do what I'm doing here put the file in a little jig and hold it against the block and do it That way so that's step number one which is to grind that down somewhat with your fine file step number two is to polish the edge Stumpy nubs uses a little ruler thing to polish though just the one eighth on the very edge The other thing you might do is hold it a block on it to hold it have common pressure all the way across So that's step number two polish that very edge Okay, now we need to polish the edge that we use the file on so you could use a block and rub that across Matthew Cremona whose primary method I'm following Uses an eight four thousand grit and then an eight thousand grit Stumpy nubs uses a three hundred and then a thousand grit diamond stone. So apparently either method works I think a hundred different methods work just pick the one that you like it and stick with it If it works for you, so I polished the edge polish the face now I need to use a burnisher to Bend over a little hook So first you need to create some excess metal flaring out and so use a burnisher To just run across it lightly. Don't put a lot of extra pressure on there Try to keep it at 90 perpendicular here and run that across then the fifth step is simply to have this at a slight angle and run across all of your edges and There you're you're bending down and creating a hook Don't do that on both sides Without too much of an angle The more angle you use the more you got to hold the cart at an angle in order to do the cutting and that Is how simple it is To sharpen a card scraper You should feel a little hook there, which I do small workshop guy sanding off
