Looking good, moving to power equipment some times will freal like taking a step back as its the unknown. But keep at it and it will become easier. Just remember the more you learn the more you realize you don't know. Just keep pushing your self to go the extra mile. One thing I noticed was the faint scratches on the blade, I'm guessing from the kydex. Little tip on that. I put 2 layers of blue painters tape on each edge bevel befor molding the sheath. It builds in a little slop which keeps the kydex from scratching the blade, and also make the knife easier to draw and sheath. Other then that I say focus on that handles, it's the interface between you and the edge. Use the grinder to remove the bulk but don't be a fridge to go after it with files, sand paper wrapped sticks or anything else. Nice smooth blended transitions is what you want. Keep up the good work, I would like to see your sling grinder.
