polishing talk aside, that handle looks very good. In what order are you gluing and cutting the handle pieces? first glue the 3 diagonally cut pieces and then cut them to slabs or vice versa?
Just guessing that alignment issues would be less when gluing up blocks cut diagonally then resawing into scales, but I usually buy precut scales so I cut and carefully sand everything so they will mate well.
I tend to do it two different ways depending on how I feel. Sometimes I just want to get started on something, so I'll glue up the cut wood pieces without gluing them to the liners, then flatten before gluing them to the liners. This requires a little less prep and lets me get right into doing something and feeling like I accomplished some work (because sometimes the first step is the hardest). Other times when I feel like spending some quality time sanding figure 8s, I'll prep everything and glue it all up at once. Just a reminder not to crank down on any clamps to avoid a glue starved joint.
So these were scales cut and glued with spacers, then flattened and glued to the liners. The advantage is the pieces only need to be flat to each other, not 100% squared all around. That's the first pic. Then before the second pic, they were flattened and then glued to the liners in the pic.



The other way is probably how everybody else likes to do it because it means only gluing once. Everything is cut, 100% squared up by sanding and dry fit testing, then glued.
