Lawn more blades make great hatchets...no so much knives, in my experience.
Great knives!
Another great, homemade drawknife made on the cheap is a simple piece of 1/8" X 4" mild steel strap, 18" long. At 5" from either end, cut halfway through the width of the strap, then hammer that portion over to double it to make handles. The sharpen the center, on the side offset from your "handles" (the blade being up a bit helps protect your hands in case of a "slip"). Wrap your handles with vynil tape or whatever, keep your edge sharp, and go to town. Cost $4 if you buy the steel...but a lot of welding shops will give the steel away for free as it's scrap.
