I have a knife with a curly birch handle and want to darken it up quite a bit. I sanded it down lightly with #220 paper and applied a coat of Minwax Dark Walnut stain on it. Wiping excess off after about 15 minutes as directed, I found it still too light and applied another coat after an hour or so of drying. I repeated removal of the excess stain and allowed it to dry overnight for at least 8-10 hours. It was a nice shade at this point, but still very tacky to the touch. Growing impatient, I washed it with soap and water to remove the tackiness and was left with the original finish just a little dirtier looking. I now have a handle that is still the same basic curly birch finish just looks a little more worn and older. Not what I am after! Any pointers here? Did I screw up by adding that second coat prematurely? I couldn’t understand why after so many hours, it was still so tacky.
