Thanks Fletch, for chiming in with your experience.
Brian - The edges are scribed by me when I make a blank for someone, but you may well end up filing them away while adjusting the shape ( if you make and changes) so knowing how to put the line back is important. The drill bit trick works pretty well. The simple ones from the knife suppliers cost less than $30. One of the forumites used to sell a high tech marker he machines, but I don't think he sells it anymore. What I like about the hand held ones ( like K&G sells
http://www.knifeandgun.com/ProductDetails.asp?ProductCode=CTS1 ) is that you can hold the blade in your hand and mark the edge. The ones laying on a flat surface require the blade to be straight,flat, and even thickness . The hand held ones can be used on blanks with bolsters, like integrals, or odd shapes.
When you first start sanding/shaping Micarta, it looks uglier than a nude pin-up of Rosanne Barr, but finishes up as an attractive and tough handle. The orange Micarta on your handle is the last of a batch I haspecial made for me many years ago. It makes a superb wilderness handle...easy to spot and good to grip. The brown material that I used for Fletch came from TKS.
Micarta can be purchases in scales, blocks, or sheets. The scales are from 1/8 to 3/8 thick, and blocks are usually 3/4" thick, The economic way to purchase the material is in sheets, which are usually 5X12" or 12X12". The sheets come in the same sizes as the scales and blocks, but are much cheaper in the long run.
Other good uses for Micarta are making work rest, jigs and clamps, and handles for files and other shop tools.
Brian - I have been handling this cutout with the scales in place and really like the feel of this knife. I think you will be very pleased with the final results you get.
Something I noticed that I don't know if you planned on or it happened that way, is that the butt and the edge line up perfectly. It makes for a clean line, and good handling. Many drop the butt too far, or make the handle too high. Yours is dead right.
