I am going to make the jump and get some prepping tools and looking for recommendations for quality air scribe or scribes from reading the posts believe 2 scribes are needed. My intended use will be to clean out the matrix left in the center whorl of ammonites I have found or future finds as well as bulk removal of matrix to tidy up around the edges to make presentable. I have the support equipment in my shop where I work on one of my other hobbies, building and maintenance of my airplanes. Have attached a couple of pictures of finds from previous trips to give an idea of what I will be working on and hope to get back in the mountains soon as the snow melts.
