Finally got around to staining around an H&B Forge tomahawk handle with some paper birch bark oil that we distilled in Scott Jones, Media Prehistoria, class a few months back. It will leave a smokey smell on your hands for hours but I love this stuff. It really pulls out the grain in the wood. I'll add another coat in a day or two and then seal it with a couple of coats of walnut oil in a couple of weeks. Yes, I did let it sit in the bottle for a few months so I had to use a double boiler to really get it back into a fluid liquid.
