This is Charles McMahon on behalf of Expert Village. I’m going to say a few things about keeping the wedge sharp. Now you can see the way this thing operates, is to drive the ram here against the log, push the log against the wedge. This wedge comes to a pretty sharp point. Now this is made out of steel but it doesn’t have to be made out of hardened steel. In other words, it’s not heat treated to a high strength. With use, this point here can get dull. So if it does get dull, what you need to do is take a flat file, bigger than this if you have one, and just file this point here; file off whatever burs are on here, whatever blunt regions there are and you can sharpen up the wedge that way. If you do that, you might just spray some oil on here so it doesn’t get rusty. You can see that it is painted now which keeps it from getting rusty but when you file it of course, you are going to expose fresh metal so you can oil this up so it doesn’t rust. So that is a piece of maintenance that you don’t have to do very often but at some point, you may need a file.
