Drawknives. They can be expensive or cheap. They are used by green woodworkers and chairmakers (for the spindles). You can use them for taking bark off trees as well. With only a $1 railroad spike and some scrap lumber you can make your own drawknife. Also view a different way of placing handles on your homemade tools tangs.
It must be noted that I do not condone taking railroad spikes off of tracks. It is illegal and you can get in serious trouble for theft and/or killed by a big freaking train. Take some drinks to a local rail yard and trade for some spikes or check out ebay.
