What you do on the next one is finish the blade all except the final sharpening. Drill the scales to fit the tang holes. First drill one scale for the front and back hole ( drill from the tang side), dropping in a pin in the first hole before drilling the second. Tape the scales together (without the blade) and drill the other scale to match. Drill one hole, slip in a pin, and then drill the other. With both pins in place to align the scales, shape the front end to the curve and profile you like, Sand, and polish in the same manner you plan to do the handle. Untape and separate the scales, assemble them on the tang to check that you like the front part's position. Tape up the blade to keep it clean, and then do the glue-up to the tang. After the resin cures, shape the handle as desired. The front will already be done, so you won't risk scratching up the blade or messing up the matching surfaces.
