Anyone that truly works with hand tools knows the value in having sharp tools. Sharp tools minimises muscle fatigue and accidents that arise from frustration by unnecessarily over exerting yourself to get the work done. Handsaws are no different to planes, chisels, or any other hand tool. A mediocre sharpened saw works well, but super sharp saws like the ones from “Bad Axe” perform better than more modern manufactured saws. Admittedly, I have never tried a “Bad Axe” saw because I live in Australia, but I have read so many articles about its superiority and cutting speed that I have only imagined how fast it actually cuts until now. I have wished to pick Mark’s brain on what rake and fleam he uses that makes his saws so superior to the way other sawyers have sharpened their saws.
Today I found an old in FWW article on how to sharpen a saw on Mark’s website. I anxiously downloaded the article and read it slowly and carefully, making sure not to miss anything. When I finished, I was a little confused. I didn’t find any rake and fleam that he favours. In fact, it says to stick with the angle determined by the manufacturer. The only thing I got from the article was the stroke method he used. Medium, heavy, then a light finishing stroke he say’s. Making sure every tooth is of equal height and every gullet of equal depth. That’s it! That’s all he does. I pulled out my saw vice and a spare LN backsaw, which I intend to sell and sharpened it using Mark’s recommendation. Upon completion, I was surprised at how prickly the saw teeth felt. I put it to the test on some scrap pine and it just went through it like butter, then I tried some white oak which he recommended and it too sawed through effortlessly. I then pulled out my other backsaw sharpened by Lie Nielson and tried it sawing white oak with it, and it struggled. I had difficulties pushing it through the wood.. I nearly fell on my arse in awe of Mark’s expert sharpening technique. The rake and fleam I used was the manufacturer’s default of 15°. What I changed was the method of stroke as per Mark’s recommendation. Not only did it saw faster, but there was zero tear out on the back. Go figure that one out. I highly recommend you download this article, read it, and then give it a go. I guarantee you will never look, read or watch another saw sharpening video again.
One last note, use the recommended size files that Mark recommends. You can find other sized files on his website. Bad Axe Saw Sharpening Files by Friedrich Dick (badaxetoolworks.com) Take the time to read his articles, I’m sure you’ll agree them to be very informative.
