Just got a Swaty from ebay; I've been using a black Arkansas and getting comfortable shaves but knew my edges weren't as sharp as they should be. Got the Swaty and put my Red Injun to it about 10 strokes/side, then 10 more as lightly as I could, then stropped. Nice shave! I realized it was much sharper when I put the blade down to start a stroke at too steep an angle and it cut me when it touched the skin. Gotta be a little more careful from now on....
