I get my hooks hand-turned from a wonderful couple.
Then I start my finishing process.
First I file and shape the hook head, testing as I go. I continue to shape and test until I feel each hook is the absolute best it can be, with a quick fluid motion as it pulls through the yarn. Then I sand the entire surface of the hook until it is completely smooth. Buff the hook with 4 different grits of buffers and polish with 3 levels of polishing blocks. At this point the messy part is done. I wipe the hook down, and then start polishing with micron grade polishing paper. I use 3-4 different levels depending upon the type and grain of the wood. After the hook is silky smooth then I apply a coat of beeswax with a little bit of coconut oil to treat and condition the wood. Then I give it one more hand polish to really work the wax and oil in.
By the time I'm done I think I've gone over the hook about 12 times, yes I could finish them much quicker if I used some sort of wood finisher, but my goal is to have a completely chemical free, natural wood, polished surface when I'm done. I love how silky each hook feels after this process, and as there is no artificial finish to wear off, your hook only gets smoother, and more polished as you crochet with it. The more you use your hook the prettier and smoother it will be, from the friction of the yarn and natural oils from your hands. Every so often you can give your hook a rub down with beeswax, coconut oil, or most any cooking oil you have on hand, and just like a quality piece of antique wood furniture it will last a lifetime.
