Looking for some experience advice. I made a knife about 4 months ago using Madrone for the handle scales. The wood was leftover from a door project and I thought it was quite dry. Just the other day I pulled it out to polish the brass ( about done with brass too but that's another story ) and found that the scales had shrunk. It's a through tang and I can now feel the steel protruding where it used to be a perfect grind. Question; are there just some woods not stable enough for scales and if so could you tell me so I don't have to keep finding out the hard way. Just made one with manzanita which is the same family and I love the look. Thanks.
